In the continuous processing machine, cold rolled steel sheet and zinc galvanized steel sheet served as basal plate, one layer or several layers of liquid paint are painted onto the basal plate after surface pretreatment. Steel sheet is changed into coated steel sheet after baking and cooling. As the layer bears different colors, thus coated steel sheet is also known as color coated steel sheet. Besides, because painting is preceded prior to the formation processing, coated steel sheet is also called as pre-coated steel sheet. .In this processing ,traditionally adopted spraying is replaced by continuous painting, which is conducive to surface treatment ,quality control of coating layer and avoid defects in edges.
Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Coil .
High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
What are the benefits and drawbacks of steel and other metal roofing materials? This unbiased, expert article gives you the pros and cons of metal roofs so you can make an informed choice about whether or not to choose metal roofing for your home.
If you are considering buying metal roofing for your home, it’s very important to weigh the pros and cons of metal against other more common roof materials, such as asphalt, wood, and tile.
This expert article offers a close look at some of the benefits and drawbacks of steel, aluminum, and other metal roofing.
Metal Roofing Benefits
Metal beats out conventional roofing materials in several ways:
Expected life. Properly installed, a metal roof should last as long as the house, sealing out water, surviving high winds, and easily shedding snow. Metal is resistant to fire, mildew, insects, and rot.
Warranties vary widely, but most companies back their products for 20 to 50 years. Paint finishes typically have a 30-year limited warranty.
Weight. Compared to the weight of tile at 750 pounds per square (an area equal to 100 square feet) or concrete tile at 900 pounds per square, metal roofing is very lightweight. Most varieties run from 50 to 150 pounds per square.
Because of the material’s light weight, you can save on engineering and building the supporting structure. In fact, if you’re building a house or an addition, you can often downsize or reduce the number of roof support members.
Some types of metal roofing materials may be applied over an existing roof without the need for tear-off or additional structural support.
Speed & ease of roofing installation. Most metal roofing materials come in multiple-shingle sections or in 12- to 36-inch-wide panels.
An accomplished contractor can install these quickly. If your roof is stripped off and a storm is on the way, shortening the process by a day or two may offer a critical advantage. Obviously, there is also considerable labor savings if you can ease and shorten the duration of roof installation.
Fire resistance. Because metal roof materials are noncombustible, they typically have a Class A fire rating (the most fire-resistant rating). Just be aware that part of a roof’s overall classification depends on materials beneath the surface that could ignite in intense heat, too. Most metal roofs applied over a combustible material such as wood shingles have a lower, Class C rating for this reason. See notes under “Metal Roofing Drawbacks” regarding problems in the event of a house fire.
Heat conduction. Metal reflects radiant heat from the sun, minimizing midday heat gain. This means you save energy needed for air conditioning during the day. Though the material itself is low in insulation R-value, metal roofing can be applied over rigid-foam insulation that has very high R-values. In addition, many systems utilize a dead-air space between the metal and roof deck to increase energy efficiency.
Minimal roof pitch. Most metal roofing materials can be installed on gently pitched roofs without leaking. Minimum roof pitch typically is 3-in-12 (the roof rises 3 inches for each horizontal foot).
Maximum shedding of rain and snow. Metal roofing is practically impervious to rain and snow because of the way the panels interlock and because the surfaces are hard and slippery. In addition, dark tones of metal roofing quickly warm in the snow, encouraging snow melt.
Metal Roofing Drawbacks
Though metal roofing offers many pluses, a few drawbacks are worthy of mention. For the most part, metal roofing manufacturers have improved their products to address or solve many of these concerns:
Cost. The biggest drawback is initial cost. Metal roofing is equivalent in cost to other premium materials—from about $150 to $600 per square (100 square feet).
Because of the material’s long-term durability, the trick is that you ultimately save the difference (and more) if you stay in the house for a long time and, of course, you save on seasonal maintenance. Then again, if you plan to move in a couple of years, you probably won’t get the return on your investment.
Noise. For some, the sound of rain tapping on the roof is romantic and homey. For others, it’s like living inside a drum. In a rainstorm or hailstorm, living beneath thin sheets of metal is bound to be noisier than living beneath thick slate or tile. Noise can be controlled both by using materials that have structural barriers to minimize the drumming effect and by applying them over sound-deadening insulation and solid plywood sheathing.
Denting. Just as your car will dent if a golf ball hits it, a metal roof can dent if large hailstones fall on it. Aluminum and copper, much softer than steel, are more prone to denting. Some types are guaranteed not to dent, however.
Though you shouldn’t have to walk on a roof that doesn’t leak, there may be occasions when a plumber needs to snake out a vent pipe or a chimney sweep needs access to the flue. You can walk on some metal roofs but not all of them. This depends on how the particular product is made and the type of construction supporting it. As you might imagine, metal can be very slippery when wet.
Marring & care. Some painted metal roof finishes can peel, chip, fade, scratch, or chalk, although nearly all are guaranteed for 30 years. Walking on some types, particularly those with a granulated-stone surface, may cause wear.
Installers must be careful not to scratch or dent the roofing during installation, and panels must be treated with care. Unlike conventional roofing, some metal shingle systems are installed from the top down, eliminating the need to walk on them. Once installed, you may need to hose off roofing now and then to keep it looking good.
Leaking. A metal roof must be installed correctly. Roofs with exposed fasteners are particularly vulnerable to improper installation. If screws attach through the flat surfaces (rather than the raised ridges), rain water can run down the roof and seep into the screw holes. For this reason, special resilient washes must seal around screw heads. If you install this type of roof, be sure manufacturer’s instructions are followed precisely.
Expansion & contraction. Because metal expands and contracts as it warms and cools, most new products have fastening systems that accommodate movement. Otherwise, fasteners that secure the roofing may tend to come loose. Expansion and contraction on hot days can cause a wavy affect.
Modifications. Metal roofing materials installed in large panels are more difficult to replace if damaged than individual shingles. Also, if you remodel or add on to your home 10 or 20 years from now, it may be difficult to match the material.
Lightning. Many people assume that because metal conducts electricity, it also attracts it. This really isn’t the case, and many instances have been documented where lightning has struck trees or other high objects located near metal roofs rather than the roofs themselves. Just the same, metal roofs can be easily grounded by a lightning protection company.
House fire. Though metal roofs are good at guarding against a fire that approaches from outside a house (such as from flying sparks and embers), they are not ideal for fires that start inside a house. With a serious house fire, firemen may need to cut through the roof to put out the fire—this job can be much more difficult and take longer if the house is capped with a metal roof.
We offer steel sheet that has an alloy coating of Aluminium and zinc often used in the insulation and ventilation industry commonly referred to by the trademark Aluzinc.
It is a good substrate for organic coating it is generally used in the manufacture of wide sections for wall cladding and insulation cladding. Supplied with a very thin organic finger print free coating for even better performance. In addition to preventing fingerprinting it also reinforces the temporary protection of the material during transport and storage. It acts as a dry lubricant and improves its forming and deep drawing performance.
In addition, it also permits the direct application of paint, without preliminary surface treatment. The many advantages of this product are highly valued in applications such as roofing sections and cladding. Material has a continuous hot dip double-sided coating. Can also be supplied with a moisture barrier for use as metal jacketing for power stations or alternatively with an acoustic barrier with significant labour saving and enhanced engineering properties (Soundmet).
Material with 185 g/m2 coating AZ185 Skin Passed Anti fingerprint lacquered coating DX51 Substrate
Can be supplied as coil or flat sheet.
Another alternative for increased rigidity is to use a Petrochem profile. The profile allows for thinner material to be used in some instances without losing rigidity. Standard thicknesses are 0.4mm to 0.8mm. Our Aluzinc product ALZN can also be combined with DryMet this adds a PSMB Surlyn barrier to the underside to prevent corrosion attacks from the internal surface that comes into contact with insulation often with changing temperatures and moisture. As well as the standard ALZN-D (Aluzinc with DryMet) it is also available with a ZX profile also called petrochem finish. Our version is ALZN-ZXD combines the performance of Aluzinc, the strength and rigidity of the ZX profile and the internal protection of the Surlyn moisture barrier.

Corrugated galvanised iron or steel (colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America) and occasionally abbreviated CGI) is a building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them. Although it is still popularly called “iron” in the UK, the material used is actually steel (which is iron alloyed with carbon for strength, commonly 0.3% carbon), and only the surviving vintage sheets may actually be made up of 100% iron. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them, because the steel must be stretched to bend perpendicular to the corrugations. Normally each sheet is manufactured longer in its strong direction.
CGI is lightweight and easily transported. It was and still is widely used especially in rural and military buildings such as sheds and water tanks. Its unique properties were used in the development of countries like Australia from the 1840s, and it is still helping developing countries today.
The corrugations are described in terms of pitch (the distance between two crests) and depth (the height from the top of a crest to the bottom of a trough). It is important for the pitch and depth to be quite uniform, in order for the sheets to be easily stackable for transport, and to overlap neatly when joining two sheets. Pitches have ranged from 25 mm (1 inch) to 125 mm (5 inches). It was once common for CGI used for vertical walls to have a shorter pitch and depth than roofing CGI. This shorter pitched material was sometimes called “rippled” instead of “corrugated”. However nowadays, nearly all CGI produced has the same pitch of 3 inches (76 mm).
Metal roofing offers a great variety of styles, materials, and colors. This guide focuses on color selection. — The item that every home owner can easily relate to.
Styles relate to the shape of the metal when installed on a roof, such as standing seam, corrugated panels, or tiles. Practically speaking, color considerations don’t matter to the style, though some styles will present slightly different colors and paint finishes.
Materials correlate with the type of metal, also called “substrate.” The popular choices for homes today are steel, aluminum, and copper. For the most part, we stick to steel and aluminum as the likely choice for most readers.
Our attention is on color. We’ll cover available options, general information on color, smart factors for selecting color and wrap up with some technical information dealing with the manufacturing of paint for metal roofs as it matters to the consumer (you).
Color choice may seem like a subjective decision, but our Guide presents (10) considerations that really shouldn’t be overlooked. There is an art and science that comes into play. Our goal is to make sure you are well versed in the considerations as well as related information.
Surprisingly, many people think of metal roofs as having limited color options. Perhaps they think the color matches the type of metal. Silver for steel, tin and aluminum; reddish-brown for copper; dark gray for lead. As if those are the extent of the color options.
With aluminum and steel, the options are a bit more than these few options. Actually, strike that. The options are limitless! The correct answer to: what are the available color options for a metal roof? All of them. All colors, hues and tints.
Instead of selecting among a few options, the homeowner actually has limitless options to choose from. In some ways, that may seem more daunting. The rest of the article will help simplify things. Well, at least until we get to the technical information.

Corrugated roofing sheets were the first design of steel profiled roofing sheets and are still very popular today. Our galvanised steel corrugated roofing sheets are a great traditional looking weather proof solution. They are manufactured to the highest quality to ensure they are maintenance free for many years to come.
Our corrugated roofing sheets are very affordable, durable and quick to install, which makes their use extremely popular in the construction of commercial, agricultural, industrial and domestic buildings. They can be fitted as a brand new roof but can also over clad an existing roof, if required, thus reducing the cost of labour. Our corrugated roofing sheets can also be used for side cladding buildings.
We have been supplying corrugated roofing sheets for over 10 years now and have a wide range available to our customers.
SHEET SPECIFICATIONS
Our traditional corrugated roofing sheets are galvanised steel and available in three gauges (thicknesses): 0.4mm, 0.5mm and 0.7mm.
The corrugations in these sheets are 3″ (76.2mm) from peak to peak and will direct any rain water away from the building.
All standard colours and finishes available
Our corrugated roofing sheets are manufactured and cut to standard stock sizes shown below or can be manufactured to customers precise requirements. They provide 990mm cover width (as standard) when lapped and fitted.
Uses: Corrugated steel roofing sheets have been around for a long time and are still just as popular today as they provide a more traditional look. They are actually the only type of cladding accepted in conservation areas. They are also ideal for barns, farm and storage buildings, stables, cattle sheds, garages, sheds and workshops etc. Our corrugated sheets can be used as single skin sheeting, overcladding of an existing roof or form part of a double skin built-up insulated system.
Benefits: Corrugated steel roofing sheets are the most robust profile with a traditional look, lightweight, easy to install, fire resistant and particularly cost effective. They are extremely weather proof and can withstand intense weather conditions such as hailstorms, heat, snow, storms and even hurricanes.
CORRUGATED GRP ROOF LIGHTS
Corrugated GRP Fibreglass rooflights also available. Our fibreglass GRP corrugated rooflights work in conjunction with our steel roofing sheets to incorporate natural daylight into your building. These rooflights allow 92% light transmission through the sheet so an excellent method to brighten up your building and reduce on electricity costs
ANTI-CONDENSATION
An anti-condensation membrane can be rolled onto the underneath of our corrugated roofing sheets during manufacturing to reduce condensation problems
INSULATED ROOFING SYSTEM – DOUBLE SKIN
Our corrugated roofing sheets can be used as the top sheet on a built up insulated roof system.
If you are one of the many homeowners looking to install a steel roof on your home, understanding the difference between galvanized steel vs. Galvalume is essential to getting the top performance you expect from your new metal roof.
Right off the bat:
In most residential steel roofing applications including near-coastal areas — beach homes located near the shore, and even homes located in the middle of heavy salt-spray — severe marine environments, Galvalume steel will be a better and more corrosion-resistant option than galvanized steel.
The one exception when Galvalume should not be used:
Galvalume steel should not be used on, in, or around concrete or mortar. Concrete and mortar are highly alkaline environments.
Did you know? Bare Galvalume steel and painted Galvalume sheets will suffer rapid corrosion when in contact with mortar and concrete.
Bare Galvanized steel and painted Galvanized perform better in this type of environment.
Now, because aluminum, one of the two metals in Galvalume coating, provides a barrier protection for steel, instead of galvanic or self-healing protection in galvanized steel, scratches and cut edges in Galvalume are less protected.
Galvalume steel is best for use in prefabricated metal wall panels and standing seam metal roofapplications with concealed fasteners.
We would not recommend using Galvalume panels with exposed-fastener steel roofing systems such as corrugated or ribbed steel roofs.
Normally, Galvalume is offered in both bare and pre-coated (pre-painted) versions. Most residential-grade Galvalume metal roofing products – like galvanized steel – are coated with Kynar 500 or Hylar 5000 paint finishes.
Galvalume has an excellent performance lifespan in bare exposures (unpainted panels) as well. Both galvanized steel and Galvalume weigh 100 to 150 pounds per 100 square feet and contain about 35% recycled steel post-consumer content.
The cost of Galvalume and Galvalume Plus are about the same as that of galvanized steel.
A product called Galvalume Plus features an extra coating of acrylic. One advantage of Galvalume Plus is that it can be roll-formed dry, without vanishing oil. Thus, Galvalume Plus is very easy to form and install safely in the field, using portable roll-formers.
What is galvanized steel:
Galvanized steel was invented and developed for commercial use in the first half of the 19th Century, so it has nearly 200 years of proven track record. Carbon sheet steel is dipped in molten zinc. It’s more than a coating, however. A chemical bond occurs and produces the telltale “spangles,” the crystalline surface pattern found on galvanized steel.
Tip: Look for G-90 galvanized steel for residential applications not G-60
What is Galvalume:
Bethlehem Steel developed the product and introduced it to the world in 1972, so it’s been in use nearly 60 years. Similar to galvanized steel, Galvalume is produced by a hot-dip process. Instead of 100% zinc, the dip is 55% aluminum, 43.5% zinc and 1.5% silicon.
Zinc bonds with the steel surface to create a barrier to corrosion-causing moisture
Aluminum is a metal that naturally resists corrosion and reflects heat too
Silicon enhances the adhesion of the coating, keeping it in place when the steel is rolled, stamped or bent
A product called Galvalume Plus features an extra coating of acrylic. One advantage of Galvalume Plus is that it can be roll-formed dry, without vanishing oil. Thus, Galvalume Plus is very easy to form and install safely.
How Corrosion Occurs in Each
Unpainted Galvalume vs. galvanized steel exposure over time.
Corrosion is the death of metal roofing, as we all know. Galvalume and galvanized steel roofing are affected differently by corrosion.
Galvalume: Aluminum has tremendous corrosion resistance, so it will generally corrode more slowly than galvanized steel. The one exception is when the coating is penetrated – scratched or chipped by falling or blowing debris, for example.
The exposed sheet metal beneath the coating will quickly corrode. However, the aluminum coating will prevent the corrosion from spreading; it will be contained.
Galvanized steel: More than just coating the steel, galvanizing steel produces a chemical bond resistant to corrosion, scratches and nicks. Galvanized steel will self-heal for small scratches and along cut-edges.
Over-time, when galvanization layer in galvanized steel panels wears down or is penetrated, corrosion will begin to spreads.
Spreading corrosion will affect steel beneath the galvanized, bonded layer, and the layer galvanization will be shed. The front line of the corrosion spreads like a storm front across a radar screen. Slowly, perhaps, but steadily.
Uncoated/Unpainted Galvanized Steel vs. Galvalume Wear: 10, 15, 20 Years and Beyond
To illustrate the difference in performance between galvanized and Galvalume steel, let’s consider how the two kinds of steel would perform in an uncoated/unpainted steel roofing application.
Note: With a quality paint finish such as Kynar 500, both G-90 galvanized steel and Galvalume steel should provide consistent, rust-free performance for 30 plus years when used in accordance with manufacturers’ specifications.
With unpainted steel (normally you cannot buy unpainted galvanized steel panels), in the short-term, galvanized steel often holds its rust-free good looks longer than Galvalume thanks to self-healing properties of zinc.
5 to 10 Years: The galvanized roof will look “perfect” accept for some corrosion beginning where fasteners penetrated steel during the installation. The Galvalume roofing may show corrosion at nicks and scratches and around field-installed fastener holes.
10 to 15 years: The Galvalume roofing will look about the same, but with a few more nicks that produce isolated spots and lines of corrosion. The galvanized steel roofing will start showing its age. Corrosion has continued to spread outward from its starting point.
20 years: The changes in the Galvalume roofing are slow and imperceptible, though if you compared a picture of the new roof to its current state, the nicks and scratches would be visible. You might also notice a slight patina common to ageing aluminum.
The galvanized roof, depending on climatic factors, might show a light rust hue. This is the result of the zinc layer wearing away, leaving the steel substrate exposed.
Beyond 20 years: The lifespan for unpainted galvanized roofing is 15-25 years depending on climate, less where oceanic salt spray is common. Unpainted Galvalume has a lifespan up to 40 years. Once corrosion has penetrated the sheet steel substrate of any steel roofing, the integrity of the steel will suffer and your steel roof will begin to fall apart.
Selecting the Right Paint Finish for Your Steel Roof
The coating or paint finish used on Galvalume is very important because it is critical to the length and conditions of the entire warranty of the steel panel product.
Over the years, coated metal roof panels have progressed from a single coat straight polyester paint system in the early years to Poly vinyl idene fluoride (PVDF) acknowledged as the premium resin for coil coatings. It is a kind of fluoride, a family that includes such well known products as Teflon and Halar.
PVDF resin has superior chalk resistance and gloss retention as well as stain and chemical resistance. It is softer than polyester, making it highly formable without risk of cracking. Current pre-treatments and primers along with superior paint coating have increased product warranties dramatically.
Did you know? Most homeowners don’t check to make sure that they are not getting the inferior straight polyester system. Straight polyester should really not be used for metal roofing and metal wall panel in today’s market.
If you see there is a dramatic difference in the price of two different painted Galvalume or galvanized steel panels, then the less expensive, less effective kind of coating should be suspected in a cheaper panel.
Tip: Always look for Kynar 500/Hylar 5000 or equivalent paint finish for residential applications.
What about horse barns and agricultural uses?
Neither Galvalume or galvanized substrate are warranted to be used, in or around animal confinement or agriculture. Bare Galvalume and coated Galvalume panels will very rapidly deteriorate when exposed to the corrosive agents of animal confinement.
But bare Galvalume and coated (painted) Galvalume panels have an outstanding corrosion resistance in a wide variety of general environments, including industrial, marine and even severe marine environments.
And Galvalume (as well as Kynar 500 coated and CoolRoof rated G-90 steel) offers exceptional heat reflectivity, resulting in lower energy load on homes and HVAC equipment, resulting in improved interior comfort and energy savings for homeowners.
Painting and Maintaining Aging Galvanized and Galvalume Roofing
Both types of steel can be painted to improve durability. Paint adheres better to galvanized steel than to Galvalume, so it requires repainting less often.
Note: With Kynar 500 or Hylar 5000 Paint finish or its equivalent, you will not have to paint over your steel roof for at least 30 years. — That’s the normal length of warranty on Kynar 500 paint finish.
When corrosion is spot-treated to stop its spread and the roof is painted when needed, galvanized steel roofing can last 50 years or more. While Galvalume isn’t yet 60 years old, the product should easily last 50+ years when painted and maintained.
Closing Thoughts on Steel Roofing
Galvanized steel and Galvalume offer excellent value – cost over their service lifespan. Unlike other roofing materials, such as asphalt, with Kynar 500 steel roofing there is no need for ongoing maintenance to ensure best long-term appearance, durability, and longevity.
The quality of the roofing installation itself plays a major role in how long a steel roof will last. Interview several qualified, experienced metal roofing contractors to discuss your options and costs for galvanized steel vs. Galvalume.
Similar to galvanized steel, Galvalume is produced by a hot-dip process. Instead of 100% zinc, the dip is 55% aluminum, 43.5% zinc and 1.5% silicon. Galvalume Steel Coil have excellent performance, possessing ideal comprehensive properties of corrosion resistance, formation and coating.
Galvalume Steel (also called Aluzinc Steel) are mainly used in building, automobiles, metallurgy, electric equipments and more.
Building – roof, door, window, roller shutter door and suspended skeleton
Metallurgy – steel sash blank and color coated substrate
Electric equipements – refrigerator base and shell, freezer, and kitchen equipment
