Stair Tread Serrated Steel Grating Custom Width HDG Surface Treatment
Hot Dipped Galvanized Serrated Steel Grating for Flooring , Stair Tread , Ditch Cover
Description:
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.
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 tread.
Clear Opening – The distance between faces of bearing bars in rectangular gratings, or between a bent connecting bar and a bearing bar in a riveted grating.
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.
