Hot Dipped Galvanized Serrated Steel Grating for Flooring , Stair
Tread , Ditch Cover
Steel grating is made by bearing bar and cross bar according to the
flat-steel weft arrangement, in high-pressure spacing on resistance
welder welded by cutting, incision, opening, overlock process such
as processing and into customer requirements finished products.
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.
Carriers – Flats or angles which are welded to the grating panel and nosing
of a stair tread and are bolted to a stair stringer to support the
Clear Opening – The distance between faces of bearing bars in rectangular
gratings, or between a bent connecting bar and a bearing bar in a
Cross Bars – The connecting bars which extend across the bearing bars, usually
perpendicular to them. They may be bent into a corrugated or
sinuous pattern and, where they intersect the bearing bars, are
welded, forged or mechanically locked to them.
Cross Bar Centers – The distance center-to-center of the cross bars.
