What Are the Uses of Corrugated Galvanized Iron Sheet?
Corrugated galvanized sheets are manufactured with galvanized steel sheets through a cold-form process where they are pressed and then roll-formed to create the desired corrugated shape. The grooves within the steel increase the tensile strength, making it resistant to increased impact and weight loads. The steel’s corrugated configuration provides one of the highest strength-to-weight ratios of any construction material. The corrugation process is accomplished by roll forming. This means that the sheet metal is pulled off of huge round metal coils and then it passes through rolling dies that form the panel into a corrugated metal sheet. After the corrugated metal sheets pass through all of the rollers, it is sheared off at the correct panel length. Here let’s have a review on corrugated galvanized iron sheet uses.

The traditional shape of a corrugated steel sheet is round and wavy. It is low cost, lightweight, durable, energy-efficient, long-lasting, and easy to install. Corrugated metal roofing is an excellent alternative to asphalt shingles or clay tile roofs. The durability of corrugated steel panels makes them a fit for both commercial and residential applications when used for metal roofing and metal siding projects. They are even used in other areas of the home including the ceiling, wainscoting, and fencing.
Galvalume vs Galvanized Corrugated Panels
The corrugated metal sheet is made from steel coils or sheets. Typically, the steel will have an underlying layer applied that is normally galvanized or galvalume coating. The main difference between galvalume and galvanized corrugated metal sheets lies in the coating finish. Galvalume coating is manufactured from a 55% aluminum and 45% zinc coating covering the underlying steel substrate. When combined with silicon, the aluminum-zinc galvalume finish bonds effectively to the steel substrate allowing for equal adhesion throughout the steel.
Conversely, a galvanized finish is composed of 100% zinc. Compared with galvalume, galvanized zinc provides increased protection from cut edges and scratches, but the overall corrosion resistance increases with galvalume.
Corrugated galvanized iron sheet (CGI sheet) is one of the most commonly used sheet panels nowadays due to its excellent durability, easy maintenance, and affordable price. It is generally made of thin plain galvanized steel sheet, stiffened by corrugations. These corrugations, such as waves or folds, not only increase the strength and stability of sheet material but also expands the load-bearing capacity without deformation. Therefore, this sort of steel product is sincerely trusted by many professionals and homeowners for many different applications. Let’s review the corrugated galvanized iron sheet uses below.
Corrugated Galvanized Iron Sheet Uses
Corrugated galvanized sheets have become one of the most sought-after roofing materials for many property owners. Used commonly for commercial, agricultural and industrial purposes earlier, it has currently become a widely used material for residential roofing projects.
1. General Construction Uses
In construction, this corrugated GI sheet has gradually replaced the old concrete, shingle, and bamboo mat roofing slabs, working as roofing, flooring, wall cladding, siding, ceiling, and partitioning material while still keeping a traditional look. Also, the incidences of water seepage into the house are greatly reduced. In this regard, numerous corrugated galvanized iron sheets are consumed yearly to fulfill this aim.
2. Base Material
CGI sheet is an important material used to manufacture different sandwich panels.
3. Safety Fencing
The corrugated GI panel can be used as a baffle for isolation and protection. These projects include stables, livestock storage, warehouses, plants, and more.
4. Other Uses
It can be used as decorative screens, interior and exterior wall decoration, indicators, advertising boards, and so on.
Why Is Galvanized Sheet So Popular?
According to the surface, galvanized sheets can be divided into regular spangles, small spangles, and zero spangles. Corrugated galvanized sheets come in varying thicknesses and specifications. The benefits of using galvanized corrugated sheets include:
1. Great Corrosion Resistance
The CGI sheet is fully galvanized to become more resistant to corrosion and rust. Zinc weathers at a very slow rate, so the coating generally has a long life, thus prolonging the lifespan of the base metal. Besides acting as galvanized protector, the zinc layer also has other functions:
– Less maintenance. CGI sheets are virtually maintenance-free.
– Easy inspection. The galvanized coating can be assessed readily by eye, and simple non-destructive thickness testing methods can be used.
2. Light Weight & Easy to Transport
With the common thickness of 0.2-4mm, you can imagine that a CGI sheet is very light in weight and easy for transportation, unloading, and handling.
3. Easy to Install & Use
The installation of corrugated GI sheets is fast and simple, without structural support and complicated tools. And each sheet can be cut randomly to suit your specific requirements.
4. Great Durability
The indoor service life of a galvanized iron sheet is more than 30 years. When used in an outdoor environment, it can last more than 10 years.
5. High Toughness
Galvanized corrugated sheet is cold-rolled to create the desired corrugated shape, which will increase the bending strength of steel in the direction perpendicular to the corrugations. Therefore, it is high in strength to withstand extreme weather, impact, and other external forces.
6. Cost-effective Solution
It can be embodied in four aspects:
– Various sizes and designs. They are generally 0.2-4mm in thickness and 750-1,250mm in width, available in different designs like wave, trapezoid, tile, and curve. What’s more, you can find corrugated metal sheets made with PPGI sheets, PPGL sheets, etc, which provide more colors to meet aesthetic requirements.
– Low cost. These sheets are much affordable and require no extra cost in installing, saving you both the time and money in labor costs.
– Nontoxic and harmless. It can be said a real green material on the market, with no smell and harmful substances. Once finished installation, it can be put into use.
– Renewable. It generates no excessive construction waste in the production and installation process. Moreover, if demolished, there is a second chance of utilization, achieving the true purpose of environmental protection. In the future, the corrugated galvanized iron sheet will have a broad market.
How to Choose CGI Sheet for Your Projects?
When you are trying to decide which of these panels is best for your project there are two main factors to consider: the cost of the panels and the look of the panels. If you want a round and wavy-looking panel, then corrugated metal is the only choice. However, if you want something that is square or boxy, then you will have lots of choices including R-Panel or PBR Panels.
If you are on a budget and saving money is the top priority then R-Panel would be the better choice. R-Panel is the nicest metal panel for the least amount of money.
Overall, R-Panel is a less expensive, stronger panel when compared to corrugated. This is why you will see corrugated used more often for roofing and R-Panel used more often for siding. R-Panel is also used more often in commercial applications where the appearance of the panel is less important than cost savings and the panel strength.
They are both great products at a good price point. You’ll have to decide which panel has the look and panel features that match best with your project. There is a third and more expensive alternative, standing seam metal roofing.
