Q235 Hot Gavlanized Steel Grating Bar Grating Stair Treads Trench Cover
Bar Grating can meet almost any load bearing or weight requirement and is the most durable grating for rugged applications. Bar grating is a top choice for strength, safety, and long-term cost.
Bar Grating consists of a series of bearing bars welded (or otherwise joined) at various intervals to perpendicular cross bars to form a load-bearing panel. Panels are manufactured by welding, locked by swaging, or press-locked processes. A typical panel configuration has bearing bars that are spaced 1-3/ 16 inches (center to center) with perpendicular cross bars spaced 4 inches apart (center to center). Other spacings are available to meet your loading and open area requirements.
Bar Grating is available in a wide selection of panel sizes; bar sizes and spacings; bar shapes; and material types. The most popular style is Welded Bar Grating.

Benefits of Product Advantage
Bar grating is forge-welded, a system in which Grating was a pioneer. In this process the bearing bars and cross rods are permanently forged together by heat and pressure into a single unit construction, resulting in greater strength per pound than mechanical assembly methods. The twisted cross rods provide a non-slip walking surface. For applications where extremely slippery conditions prevail, Serrated bar grating offers a superior grip surface to the load bearing bars.
