Welded steel bar grating

Welded steel bar grating is the most popular grating type amoung gratings, because its strength, low cost for production and easy,quick installation. Widely used in most of general industrial plants as well as commercial buildings, it has various applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.

It is also good solution for use as mezzanine decking since it supports the same loads as concrete 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. Standard panels are available in widths of 2', 3' or 4'.

 

Welded steel bar grating is resistance welded to create a rugged, one-piece constructed panel. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.

Common sizes of our steel grating bar:
Pitch of Bearing Bar
A center distance between the two bearing bars adjacent to each other.
Common pitch : 30mm & 40mm
Other : 12.5mm, 15mm, 25mm, 60mm
Pitch of Cross Bar
A center distance between the two cross bars adjacent to each other.
Standard pitch : 50mm & 100mm.

NOTE: Difference spacing of bearing bar & Cross bar can also be manufacture upon request.
Uses: Electro-Forged Steel Grating can be used as industrial trucks, stair treads and various floorings.
