Light Bar Grid Steel Floor Grating Architectural Metal Grates
There are 4 shapes of bearing bar as following:
1. Plain type: One of the most wiely used gratings, available for flooring, sidewalk, dranage pit cover, stair tread, etc.
2. Serrated type: Better Non-skid property & safety compared with plain grating.
3. I-shape type: Lighter, more economical and practical comparing with plain grating.
4. Serrated I bar: Better Non-skid property & safety comparing with I bar grating.

Sign of the shape of bearing bars:
F- Plain style
S- Serrated style
I- I-section style
Sign of surface treatment:
G- Hot galvanizing (it is recommended)
-flooring steel gratings
-Stanchions (hand rails)
Standard steel grating supplied is manufactured with a resistance-weld process using heat and pressure. Crossbars are fused to bearing bars to assure maximum strength.
Intensity, light structure: strong grid bonding structure makes it with high load, the structure characteristics, facilitate hoisting light; Beautiful appearance, durable: hot-dip galvanized surface treatment make it fairly good corrosion resistance, the surface luster beautiful; Ventilation, lighting, heat dissipation, explosion-proof, prevent slippery properties is good; Deposition prevention dirt.
