1. GI Roofing Steel Sheet introduction
It is a plain carbon steel sheet coated in a galvanizing process that applies a barrier of zinc to
insulate it from the elements. Most of the corrugated roofing and siding products seen today
and for many years past are made with a galvanized finish



2. GI Roofing Steel Sheet application scope
It is most commonly used for commercial, agricultural, and industrial purposes, however, it is
now also being recognized as an excellent form of residential roofing



3. GI Roofing Steel Sheet advantages compared with normal one
A normal steel sheet will rust almost immediately, but galvanizing will protect the steel. This
galvanized, eltro-coated, hot-dipped process produces a silvery look or spangled finish. As
a standard, several of our industrial metal siding, metal roofing, metal decking, corrugated
metal panels and accessories are made in galvanized steel
