With Twisted Steel Bar 6*6 5*5 8* Hot Dipped Galvanized Steel Grating for Platform




Hot Dipped Galvanized Steel 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.


Steel grating plate, also known as steel grating, grille plate, is flat steel in accordance with a certain
spacing and cross bar arrangement, and welded into a middle with a square grid of a steel products, mainly used to do ditch cover Plate, steel platform plate, steel ladder of the step board. The bar is generally made of twisted square steel.


Twisted steel bars are the steel bars which comes with the right combination of Strength & Flexibility. This elongation helps to protect any construction structure.The mechanical interlock between steel and concrete is critical in reinforced concrete. Early concrete reinforcing was sometimes smooth and square. This shape did not create much friction to make a solid interlock. One solution to this problem was to twist the bar like a corkscrew with creates many teeth for a strong mechanical lock. The primary drawback to doing this is that the twisting causes the steel to work harden and become more brittle.

Trim Band: A band which carries no load, used primarily for appearance and closing open ends.

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.
