Astm A653m Galvanized Steel Sheet Grade 340 Hot Dipped Galvanized Steel Plate
Galvanised steel material plays a vital role in industries requiring, such as construction,
automotive, and appliance manufacturing. Zinc coating provides lasting protection against
rust and environmental wear, making it ideal for outdoor and moisture-prone applications.
ASTM A 653A 653M is a standard specification for hot-dip galvanized steel coils. It sets the
requirements for the composition and quality of the zinc coating to ensure consistent
performance and durability. This standard is widely recognized and used in the industry
to ensure the reliability and consistency of galvanized steel coils.

2 kinds common used surface
On the surface of galvanized steel material, you will see a pattern that looks like it has formed
naturally. It is a pattern formed by the crystallization of zinc element during the cooling process
after molten zinc is attached to the surface of steel material. This is called Spangle.
♦ 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 application that emphasize visual and decoration effects. The
rough spangle helps to improve corrosion resistance, especially in harsh environment 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 plain sheet. The advantage of zero spangle is that the finish is extremely good, very beautiful, and
the coating will be denser and even.
Zero spangle is mostly used in areas with extremely high appearance quality requirements,
such as precision electronic equipments and exterior parts of high-end automobiles.
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 galvanized steel material offers an economical balance of performance and durability.
we are galvanised steel supplier specialising in affordable prime galvanised steel that maintains
high functionality and quality, making it a practical option for various industries.
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, I show it in the chart below.
