Product Description: point drainage steel grating


Panels of Neo-bridge Gratings are manufactured by the programmed control press-welding machines which are developed by us with the spaced twisted square bars pressed into the bearing bars producing strong welds and rectangular opening. Bearing bars carry loads. Cross bars fix bearing bars. The direction of bearing bars represents the direction of steel grating length. The direction to cross bars represents the direction of steel grating width. for more information please tel or mail us

2.bar steel grating

Welded Steel Bar Grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Universally used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.

It is also ideal for use as mezzanine 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. 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.

3.serrated steel grating

We produce three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating.

      There are two faster methods for the steel-grating. If there’s no need of loading after installation then it can use welding method. Weld the four corners of the steel-grating and the supporting member. The welding slot height is 3mm.The welding slot length is less than 20mm. To remove the steel-grating frequently then it necessary to use the saddle-clip. Every piece of steel-grating needs at least fours addle clips . fasten and fix the four corners to the supporting parts. As for the method of  application. Please see figure. Our company can provide the above saddle clips. The user can select them when ordering steel-gratin. And please mark which kind of type you want to use.
