Flat Bar Serrated type and I-Shape type Hot Dipped Galvanized Steel Vehicular Grating
Specification
Steel bar grating is the product in accordance with customers requirements that is lined by load flat steel and horizontal rod alternately in a certain space, welded into primary plate in the high voltage resistance welding machine, then through the deep-processing of such working procedures as cutting, slitting, tapping, bordure, etc.
Bearing Bars – Load carrying main elements made from steel, aluminum, or
stainless steel, extending in the direction of the grating span.
Bearing Bar Centers – The distance center-to-center of the bearing bars.
