Description:

 

Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers and airports. Since these conditions can range from light-duty forklifts to heavy-duty truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings.

Standard heavy-duty bar grating is resistance-welded for durability, strength and safety using an automated electric/hydraulic welding process. High temperatures, combined with high pressure, fuse the bearing bars and cross bars together to form a permanent joint.

Product Description

1. The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type and I-Shape type
2. Bearing bar pitches can be 12.5, 15, 20, 30, 30.16, 32.5, 34.3, 40, 60mm, of which 30mm & 40mmare recommended.
3. Cross bar pitches can be 38, 50, 60,100mm, of which 50mm & 100mm are recommended.
4. Surface treatment: Hot-dip galvanizing, paint or other anti-corrosive coatings are available, of which hot-dip galvanizing is generally recommended.
5. Material: ASTM A36/SS235JR/SS400/Q235B
6. Tolerance The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.

 

Applications of heavy duty steel grating

Heavy-duty steel grating is widely used as the floors, lanes and rack accessories in the highway, bridge, parking lot, store shelves for large cargo, industrial plant that often use forklift and the traffic junctions, roads or trails that large trucks often come and go.
