Hot Dipped Galvanized Metal Grating Bar Safety Walkway Steel
Grating
Steel Grating Introduction
steel grating is manufactured using an electro-forgewelding process
that applies pressure and heat to fuse square, twisted cross bars
into load-bearing bars of various thicknesses and depths.The result
is a product of one-piece construction that complies with
AS1657-2013.
The press welded galvanized steel grating/grille/grate is made of
load flat steel bar and cross bar, placed horizontally and
vertically, and at an equal pitch apart, by welding with 200-ton
hydraulic resistance automatic welding equipment, then
cutting,punching and banding ends.
