hot dipped galvanized press welded 2mm steel grating for drainage
channel
Serrated welded steel grating is made of low carbon steel and stainless steel. With the features
of high strength, high bearing capacity, non-slip, anti-corrosion,
high safety performance, do not accumulate rain, snow and dust and
long lifespan, it is widely used as platforms, stair treads,
walkaway and floors in industrial, civil and commercial buildings.
Welded steel grating, is the most popular and common type of steel grating. As you can
see from the name, the technology is pressure welded. First we put
the bearing bar/flat bar into the mould, the cross bar in the
machine, then 2 cross bars will come out, by high temperature the
cross bars will be welded into the bearing bars.See below pic for
reference.
Galvanized steel grating, is steel grating being hot dip galvanized.Steel grating, is also
named as metal bar grating, it is made by welding flat steel and
bars with certain distances. Metal bar grating can be defined as a
series of metal bars positioned vertically, placed an equal
distance apart and joined by cross bars or twisted rods members to

platforms, trench covers, fences, and other properties. We supply
standard panels and customized gratings as per clients
requirements. Hot dipped zinc coating gives protection for steel
grating, it can prevent steel grating from rust.
MATERIALS
Mild Steel grating load bars are manufactured from steel that
complies with AS/NZS 3679.1:2010 grade 300 (or equivalent)
