Welded Steel Grating
Welded steel grating is the most popular and versatile of all the industrial grating types. It consists of bearing bars that are automatically resistance-welded with the cross bars via precise use of intense heat and pressure. This produces a rugged, one-piece panel with cross bars that are extremely rigid, yet smooth enough for easy, safe walking. Both plain and serrated surfaces are available. It is widely used as walkways, safety barriers, drainage covers, platforms, ventilation grates and stair treads.
Specification
19-W-2, 19-W-4, 15-W-2, 15-W-4, 11-W-2 and 11-W-4 are commonly used industrial grating sizes. Of which, for example, 19-W-4, W stands for welded steel gratings. 19 represents the spacing between bearing bars is 1-3/16 "on center while 4 means the spacing between cross bars is 4" on center. Other sizes are much similar to 19-W-4.
