Hot DIP Galvanized Mill Finish Plain Type or Serrated Type Steel Walking Bar Grating
Pressure Welded bar grating is forge-welded, a system in which 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.
Bar grating types are specified by bearing bar spacing followed by cross rod spacing.
