Steel Bar Grating, also known as Welded Steel Bar Grate, is made by Carbon or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Industrial bar gratings can be actually made from copper, aluminum and other materials, while galvanized steel grating is the mostly used one due to its economic cost and good property. And it is extremely strong and durable for all load bearing applications and is primarily used for pedestrian and light vehicle traffic. Steel bar grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements. Available in either smooth top or serrated for slip resistance.our products are produced by automated welding machine, the grating appearance is much better than hand-made steel gratings, and machine can improve our work efficiency, then we can shorten our delivery time.
