Product Description

Steel Bar Grating, also known as Welded Steel Bar Grate 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.There fare four types are available:  flat(plain), serrated for slip resistance, I shapped, serrated I shapped.


.


Serrated steel bar grating has better slip resistance and can also be widely used in steel structure platforms, sidewalks and drainages, compared with plain style steel grating. We can design and manufacture standard steel grating, with a width of up to 1 meter, and in customized shapes per client requirements
