Heavy-duty welded steel grating is manufactured by fusing bearing bars and cross bars together at high temperatures to form a permanent joint. This type of grating utilizes deeper and thicker bearing bars to provide greater durability, strength and rigidity than light-duty grating options. Available material types include economical carbon steel and corrosion-resistant stainless steel.Designed to carry heavy rolling loads and maintain the same level of performance over many years of use, heavy-duty welded steel grating is ideal for a variety of applications. Common uses include airfield landing mats, highway bridge decking, ventilation grills, curb inlet grates, ramps, docks, sidewalks, concrete reinforcements, vault covers, industrial flooring, trenches, marine platforms and paper mills.


There are several elements to be decided before choosing metal gratings. First, you should understand the environments where steel grating will be used. If the environment is wet or corrosive and should be anti-skipping, aluminum or stainless steel grating would be better choice in long terms.Second, the frequent passenger. Generally speaking, standard bearing bar spacing is enough to ensure free pass. However, if the traffic is heavy, you should consider 7/16 or 1/2" spacing which will reject high heels and ADA.Third, the load capability in unsupported clear span.


Heavy Duty Carbon Steel Grating is primarily used where heavy vehicular traffic is utilized. This product is resistance-welded for durability, strength, and safety using an automated process. This process uses high temperatures and high pressure to form a permanent bond between the bearing bars and cross rods.


Heavy Duty Grating is particularly applicable in applications such as highways, bridges, and industrial plants utilizing fork lift trucks. It is recommended that the grating be load banded when rolling wheel loads are used to provide added lateral strength. Most common bearing bar and cross rod spacing is 19-4 (1-3/16” and 4”, respectively).
