PRODUCT FEATURES

Bar Grating consists of a series of bearing bars cross jointed by welding at various intervals with crossbars (twisted square bars, square bars, round bars, flat bars, etc.), to form a kind of steel products with square lattices among them. 

Steel Gatings are designed and manufactured by pressure-welded steel gratings and are widely used in various industrial civil buildings such as urban roads, squares, gardens, docks, airports, parking lots, highways, railways, and industrial engineering.

Material: Low carbon steel, stainless steel

Surface treatment: Hot dipped galvanized, painting

Common sizes as follow:

Bar Grating

Bar Grating Application:

  • Industrial platform flooring 

  • walkway

  • traffic

  • steel structure

  • drain covers

  • steelwork platform panels

  • steel stair treads

Bar Grating Features: 

1. Beautiful appearance: simple lines

2. The best drainage: the leakage area is 83.3%, which is more than twice that of cast iron.

3. Hot-dip galvanized: strong anti-rust, maintenance-free and replacement.

4. Anti-theft design: The cover and frame are hinged, which is anti-theft, safe and easy to open.

5, Save investment: long span, under heavy load, the price is lower than cast iron and save the cost of theft or crash replacement.

6, High strength: strength and toughness are much higher than cast iron, can be used in terminals, airports and other large spans and heavy load environments.

7. Many specifications: meet the requirements of different environments, loads, spans, sizes and shapes
