Q235 Hot Gavlanized Steel Grating Bar Grating Stair Treads Trench Cover
Description:
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.
