Anti Corrosion Steel Serrated Bar Grating Trench Cover Drain Grill
Anti-Corrosion Trench Cover Drain Grill Grate Galvanized Serrated Bar Grating
Galvanized serrated bar grating discription:
Steel Grating is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and other processes. The products enjoy the feature of high strength, light structure, high bearing, convenience for loading and other
features. The hot dipped zinc coating gives the product excellent anti-corrosion.
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.
Galvanized serrated bar grating surface process:
There are three types:hot-dipped galvanized , electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.surface treatment.
