500-800g /70um-120um High Zine Coated Steel Bar Grating for Covers , Stairs , Fence
Specification
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.
Galvanized Steel Welded Bar Type Grating Structural Panels for Platform Channels Construction, Electro or Hot Dipped Galvanized with Zinc Plating Anti-Corrosion Treatment.
Steel Bar Gratings are suitable for building materials applied for power stations, boiler, ship building, petrochemical, chemical and general industrial factory buildings and municipal construction. Also known as Welded Steel Bar Grating or Pressure Weld Steel Grating.
Platform Steel Grating Channels - Big Span Steel Grate Structure Panels
Platform Channel Gratings are made of aluminum or steel alloy bar structure panels with big bar spacing and strong ability of anti-side shocking. Can be supplied with checkered plate shielding, installation connectors and other accessories.
Platform Steel Bar Grating are new building materials used in construction of power plants, boilers, ship buildings for platform decking structure. The steel bar grating platform structures enjoy good air and light ventilation, non-slip property, good bearing capacity, easy cleaning and installation.
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 features of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion resistance.
