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.
| inch | mm | inch | mm |
| 24 | 610 | 40 | 1000 |
| 30 | 762 | 48 | 1219 |
| 36 | 914 | 50 | 1250 |
Special width, some industries may use custom widths, which need to
be ordered
according to specific requirements.
