Galvanised Steel Flat Bar Grating | China Steel Grating Supplier
Welded Steel Bar Grating (Metal bar grating) can be defined as a series of metal bars positioned vertically, placed an equal distance apart and joined by cross members to form a rectangular or reticuline pattern. Typically manufactured from mild carbon steel, 6000 series aluminum and 300 series stainless steels, bar gratings are also available in specialty metal alloys to suit nearly any application.
Manufactured by assembling a series of equally spaced metal bars to connecting cross members, bar grating is available in three popular materials; mild carbon steel, 6000 series aluminum, and 300 series stainless steels.
