With Round Bar or Twisted Bar Galvanized Steel Bar Grating for Platfrom

Description:

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 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.

Steel grating advantage

It is also ideal for use as mezanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness. And, where insurance codes permit, additional sprinklers can often be eliminated.
