PRODUCT DESCRIPTION

Roofing sheets metal Q235 iron sheets roofing Galvanized corrugated steel sheet is made of Galvanized steel coil, by rolling into a variety of corrugated sheets, the hardness of steel plate material is G550(≧HRB85). We checked strictly on the quantity numbers of how many corrugated wave peaks and valleys for each specification.And the diagonal lines are same and equal for each sheet. The thickness,width and numbers of wave peaks and valleys are very strictly exact and confirmed for every order. During the installation,there is much less connection area with no gap.
Hot Dipped Galvanized Steel Sheet in Coil (GI coil) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface.
It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristic. Usually hot dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
