Steel grating is manufactured using an electro-forgewelding process
that applies pressure and heat to fuse square, twisted cross bars
into load-bearing bars of various thicknesses and depths.
The result is a product of one-piece construction that complies
with AS1657-2013.
The press welded galvanized steel grating/grille/grate is made of
load flat steel bar and cross bar, placed horizontally and
vertically, and at an equal pitch apart, by welding with 200-ton
hydraulic resistance automatic welding equipment, then cutting,
punching and banding ends.
Features of galvanized welded ctwalk steel deck metal grating
prices:
1) High strength and light structure
2) Powerful anti-corrosion, durable and long working life
3) Beautiful appearance, bright surface
4) No dirt-rain-snow deposit, automatic cleaning, easy maintenance.
5) Good ventilation, day-lighting, heat-dispersing, resistant to
sliding and explosion
6) Easy installation
Galvanizing steel grating / grille / grate is widely used in the
platform, corridor, bridge, well covers, stairs,fencing for
petroleum, chemical, power plant, waste treatment plant, civil
engineering projects and environmental projects.
Bearing bar
- A flat bar withstanding the main load is in consistent with the
span direction .
bearing bar pitch
- the distance center to center of the two bearing bars.
Cross bar
- the connecting bars , made from twisted bar ,round bar or flat
bar, which extend across the bearing bars
Cross bar pitch
- the distance center to center of the two adjacent cross bars.
Length
(span)- the maximum dimension of a grating panel ,measured parallel
to the bearing bar ,and in the same direction as the bearing bars .
Width
- the maximum dimension of a grating panel ,perpandicular to the
bearing bars .and in the same direction as the cross bars.

Hot dip galvanized steel grating advantages
(1)Attractive appearance: Simple outline.silver colour,and modern.
(2)Optimum water draining: Water leakage area is 83%,which is two
times larger than that of cast iron.
(3)Hot dip galvanized surface:Good anti-rust performance,maintain
free and replace free.
(4)Saving investment: With large span,the cost is lower than that
of cast iron when under heavy load.
(5)High strength:With strength: With strength and toughness far
higher than those of cast iron,it can be used in the environment
with large span and heavy load,such as the wharf and the airport.
(6)Many specifications available: The requirement of different
environments,loads, spans,sizes and shapes can be satisfied.
