Peru Regular Spangle Zinc Coating Gi Corrugated Roofing Iron Sheet

Product Description

1. Brief 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. Roofing 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. 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. Advantages
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

5. Technical Processing
Hot rolled steel coil -->Cold rolled- >hot dipped galvanized/ galvalume- > corrugated-->packing
