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. For example:


1. General Roofing Purpose
In construction, this corrugated GI steel 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 to the house are greatly reduced. In this regard, numerous corrugated galvanized iron sheets are consumed yearly to fulfill this aim. 
2. Base Material
CGI steel sheet is an important material used to manufacture different sandwich panels.
3. Safety Fencing
The corrugated galvanized iron sheet 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 This Material Is So Popular?
These galvanised profile roofing sheets are incredibly popular for a number of reasons.
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. Galvanized coating can be assessed readily by eye, and simple non-destructive thickness testing methods can be used.
2. 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.
3. Great Durability
The indoor service life of a corrugated galvanized iron sheet is more than 30 years. When used in an outdoor environment, it can last more than 20 years.
