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 ?
Corrosion Resistance and Longevity
Galvanised steel’s zinc coating provides a resilient barrier against rust, prolonging its lifespan
in environments exposed to moisture or extreme conditions. This quality makes it an excellent
choice for construction, infrastructure, and automotive applications.
Cost-Effective Durability
Choosing galvanised steel offers an economical balance of performance and durability. Norex is
a galvanised steel supplier specialising in affordable non-prime galvanised steel that maintains
high functionality and quality, making it a practical option for various industries.
Versatile and Aesthetic Appeal
Galvanised steel’s sleek finish and uniformity provide both aesthetic appeal and practicality, perfect
for use in architectural elements, roofing, and appliance exteriors. Its adaptability across various
formats like galvanised sheet metal, coils, and plates makes it easy to customise for specific project
needs.
Export Forms
We can export the galvanized steel material with 3 kinds form, coil, strip and sheet,
customers need to choose it accrording to their actual usage.
For the sizes, it has some regular used widths, any length is available.
| inch | mm | inch | mm |
| 24 | 610 | 40 | 1000 |
| 30 | 762 | 48 | 1219 |
| 36 | 914 | 50 | 1250 |
For some special widths (18 inch, 96 inch etc) some industries may use custom widths,
which need to be confirmed according to specific customer requirements.
