Corrugated Galvanized Iron or Steel sheets are a lightweight roofing material made of thin sheets, stiffened by corrugations. Corrugations, such as waves, considerably increase the strength and stiffness of the lightweight material. Indeed, without these waves, the metal sheets are fragile and highly deformable. The durability of corrugated sheet 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 as fencing.
Characteristic of Corrugated GI Sheet: 1.Light weight. 10-14 kg/m2, equivalent to 1/30 of a brick wall. 2.Heat conductivity. λ<=0.041w/mk. 3.High intensity.Can be used as ceiling envelope plate bearing, bending and compression resistance; Ordinary houses do not use beams and columns. 4.Bright color. No surface decoration, color galvanized steel anticorrosion coating in 10-15 years. 5.Flexible and quick installation. The construction period can be shortened by more than 40%
