1. Introduction (Corrugated Steel Sheet/ prime Hot Dipped Galvanized Corrugated Steel Sheet)
HDG & PPGI
A Base Sheet: Galvanized Steel Sheet/ GI sheet
Corrugated sheets are made from Galvanized steel coils, Galvalume Steel coils, Galvalume Pre-painted
sheet and aluminum sheet, pre painted hot dip galvanized steel coils.
Corrugated steel roofing sheets are featured with easy installation, high strength and low in lost.
They are widely use as the wall or roof of prefab house, factory, warehouse, garage, exhibition center,
cinema etc.
B Coating:
Organic fluorine resin which has good appearance of anticorrosion. Its coating has good adhesion,
high tenacity.PE PVDF Surface finish coats can be calssified into groups as follows: polyester(PE),
silicone modified polyester(SMP), High durability polyester(HDP), polyvinylidene fluoride(PVDF).
Then the ppgi coil will be roll formed by roll forming machines. Its thickness and color can be different.
