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
