Weight Standard Welded Steel Grating

The bearing bars and cross bars are resistance welded under high heat and pressure to form a permanent joint. This technology can not only ensure the rugged structure of welded steel grating, but also can retain a smooth and flat surface, which is easy and free to walk. Welded steel grating can be made of various materials, such as carbon steel Most economical standard welded grating, with maximum standard opening for flow of air and liquids, and for heat and light transference. WF – (W-19-2) For general purposes with bearing bars on 1-3/16-in. centers and cross bars on 2-in. centers.

Steel Bar Grating

Product Overview. Steel bar grating is manufactured from ASTM A-1011 mild carbon steel and is available in three distinct products: type “W” welded bar grating, type “SL” swage locked grating, and type “DT” dovetail pressure locked grating. All products are available with bearing bar spacing ranging from 19/16” (1-3/16”) to 7/16 Durable Safety Standard Welded 30x3 Steel Bar Grating From China. Description: Steel grating is welded by the world first-class equipment,which can arrange the bearing bar and cross bar. in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high. tension resistance weldingring which is controlled by Standard steel grating is ideal for platforms and flooring. Standard steel grating,monly refers to welded steel grating in large sizes. Easy fabrication and high loads structure is widely used as steel grating platform, walkway, bridge decking and flooring. Carbon steel or galvanized steel material options. Cutout or toe plates are optional. Themon specifications of I type steel grating sizes as follows: 40x5x3, 32x5x3, Closed Bar Grating. The closed bar is usually used in the ditch cover plate, the stair treads, the boiler Open Steel Grating. 1mx6m and 5.8mx1m with opening gratings are the most standard platform size, and it is TYPICAL STAIR STRINGER DETAIL.

How to calculate the weight of steel grating

The actual weight and theoretical weight of the steel grating will be different due to the different edging, openings and cuts, and the different surface treatment methods. In the delivery and settlement of steel gratings, the calculation basis is unified based on theoretical weight. Wt=(b1t1N1+b2t2N2+2b3t3)ρµ×10-6Wt—weight of steel Bar grating in Light or Heavy Duty welded steel grating: Light Duty steel grating ranges in size from 3/4 x 3/16 to 2-1/2 x 3/16 Heavy Duty steel grating ranges in size from 1 x 1/4 to 6 x 1/2 Complete Carbon Steel Grating Section of our Catalog (PDF) Metal Grating Catalog (PDF) Metal Grating Catalog (Interactive) t1: Distance between the center to center of the bearing bar. q1: Distance between the center to center of crossing bar.
