Manufactured
Welding grating is manufactured by high voltage resistance pressure welding machines, plain grating is the standard type most commonly used, skidproof, and material-saving. Surface treatment can be galvanization, bitumen dipped or painted.
Products can be manufactured according to other standard as agreed by both parties, such as the british standard bs4592: 2006, german standard din24537-1:2006, american standard ansi.Naamm mbg532-00, australian standard as 1657-1992 and so on.
