Steel grating by the grid load on certain flat steel bar and
spacing Affairs with the high pressure resistance welding machine
welded together on the original plate. With the character of
high-intensity, light structure and good ventilation. It be widely
used in corridors, bridge, ditch cover, covers, ladders, and so on.
Raw Material:
Grid load flat steel bar: High-quality low carbon steel, galvanized steel, stainless steel,
alloy steel.
Horizontal pole: Q235A or 304 stainless round steel, twisted square steel, square
steel and hexagonal steel.
Classification: Welded steel grating, standard pressure lock grating, dense
grating, ditch cover and ladders
Features: Strong steel structure made it have a high carrying capacity; With
good corrosion resistance through surface by hot-dip galvanized;
light structure easy to lifting; flat serrated have the character
of safety and anti-slip; ventilation, lighting, heat,
explosion-proof.
Finish treatment: Hot dipped galvanized, cold dipped galvanized, spray painting, dip
anti-rust oil, can prevent oxidation.
Surface type: Flat type, serrated type, I shape type (According to requirement
made different protective treatment).
Flat type: The most widely steel grating.
Serrated type: With better non-slip.
I type: On the surface, path and items not in the same flat. With
the character of light weight, economic and practical.
Application of steel grating:
- All kind of plant, such as power plants, chemical plants, steel
plants, oil plants, paper-making plants, and so on. Used as
platforms.
- All kind of shipping, used as platform of ramp, channels, pumping
stations and engine room.
- All kinds bridge, such as side road of railway bridge, suspension
bridge, trestle bridge. Used as panel shop.
- Used as drain covers and road fence at municipal engineering and
road.
- Other uses, such as oil platform, wharf road, washing platform,
tower platform and building fence, and so on.
