JIS G3302 Z12 GI Galvanized Plain Sheet For Automotive Industry

Galvanized Steel Sheet is intended for use where greater corrosion protection is required
without painting. Galvanized sheet have a rust free protection for up to 25 years, while

maintaining strength with a durable surface coating.

2 kinds common used surface

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

it 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.

For example, faster cooling often leads to the formation of small spangles, while slower cooling tends

to form large spangles.

♦ 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 can be seen, just like an ordinary piece of

steel sheet. The advantage of zero spangle is that the finish is extremely good, very beautiful, and

the coating will be denser and even.

For industries that involve precision manufacturing (such as medical equipment and electronics),

zero spangles can achieve higher quality standards in meticulous processes.

galvanized steel material application

• Automotive Industry

The use of galvanized steel on vehicles have a very long history .

The automotive industry relies on these sheets for various components, including body panels, chassis,

and even exhaust systems. The galvanized coating provides exceptional protection against rust, ensuring

that your vehicle remains in top-notch condition for a longer time.

• Electric Equipment and Appliances

When you look at most electric appliances around you, you may be able to notice the unique features

of their casing. Most casings for electrical equipment use galvanized steel material. In fact, it is not

surprising that some interior parts of these appliances are made from this steel material

• 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.

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, any length is available.

For some special widths,(such as 18 inch, 96 inch)some industries may use custom widths,

which need to be ordered according to specific customer requirements.
