100X8mm ASTM A123 Steel Serrated Bar Grating Stair Treads
Stair Tread Used Anti-Corrosion Hot Dipped Galvanized Serrated Bar Grating
Galvanized serrated bar grating introduction:
Steel bar grating is a good choice for strength, safety, long-term cost and durability. Bar Grating consists of a series of bearing bars, welded (or otherwise joined) at various intervals to perpendicular cross bars to form a load-bearing panel. It is available in a wide selection of panel sizes; bar sizes, and material types.
Stair treads are the horizontal sections of stairs that serve as the step surface of each step.
Galvanized serrated bar grating details:
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.
