AISI ASTM DX52D Z140G/M2 4x8 Flat Galvanized Mild Steel Plate
Galvanised steel, also called GI steel, plays a vital role in industries requiring durability,
corrosion resistance, and adaptability, such as construction, automotive, and appliance
manufacturing. This steel’s zinc coating provides lasting protection against rust and envir
-onmental wear, making it ideal for outdoor and moisture-prone applications.

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 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.
♦ Regular spangle
Regular spangle is known for their unique, rough, petal-like crystal, 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 crystal 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 even.
For industries that involve precision manufacturing (such as medical equipment and electronics),
zero spangle can achieve higher quality standards in meticulous processes.
Why Choose Galvanised Steel ?
