Quality Inspection for Hardend Steel Plate - Plain Sheet – Shengsong

Corrugated Galvanized Steel Roofing Sheet 

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 finish
As with almost any product the finish of the galvanized metal finish will change over time. After a period of time, the surface will appear to have a white oxide look. When this happens the material is actually protecting itself from further damage. We stock and sell several corrugated and decking panels in either a (G-60) or (G-90) level of galvanizing

3. 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

4. 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
