ASTM A653 G60 Galvanized Steel Sheet Used For Building Material 

Galvanized Steel Sheet is intended for use where greater corrosion protection is required 
without painting. A lower cost alternative to stainless steel, galvanized sheet have a rust
free protection for up to 20 years, while maintaining strength with a durable surface coating. 

2 kinds common used surface

On the surface of galvanized steel, we will see a pattern that looks like it has formed naturally.

This is called spangle. It is actually a pattern formed by the crystallization of zinc element during

the cooling process after molten zinc is attached to the surface of steel material. The formation of

spangle is affected by the temoerature, cooling rate and the chemical composition of the zinc layer.

♦ Regular spangle

regular spangle are known as their unique, rough, petal-like crystals, which provide a very strong visual 
impact. These spangles are suitable for applications that emphasize visual and decoration effects. The
rough spangle helps to improve corrosion resistance, especially in harsh environments such as high
humidity areas, marine climates areas.

♦ Zero spangle

Zero spangle means that there are almost no zinc crystals and no pattern can be seen, just like an
ordinary piece of metal sheet. The advantage of zero spangle is that the finish is extremely good, very
beautiful, and the coating will be denser and more even.This smooth surface characteristic also makes
the coating more durable.

galvanized steel material application

• Building and Construction Industry

The sturdiness and durability that galvanized sheet metal offers make it popular in the construction

industry,such as roofing sheet, grilles, gutters, rolling door etc. It has been employed in various commercial

and residential projects.

• Automotive Industry

The use of galvanized steel on vehicles have a very long history . Using zinc-coated bodies on automobiles
has become the norm of car manufacturing. 

• Telecommunication Industry

Maintaining phone lines isn’t an easy job. They require the toughest and most reliable material for success.
Galvanized steel sheet offers its uses on phone wiring and equipment boxes. 

export forms and common dimensions

We can export the galvanized steel material with 3 kinds form, coil, strip and sheet,
customers need to choose it accrording to their actual application.

For the sizes, it has some regular used widths.

Special width, some industries may use custom widths, which need to be ordered
according to specific requirements.
