BS729 Standard Galvanized Finish Civil Engineering Serrated Steel Grating
Serrated Steel Grating Introduction:
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. Available in either smooth top or serrated for slip resistance.
