Durable Serrated Galvanized Steel Grating Anti Rust For Industrial
There are 4 shapes of bearing bar as following:
1. Plain type: One of the most wiely used gratings, available for
flooring, sidewalk, dranage pit cover, stair tread, etc.
2. Serrated type: Better Non-skid property & safety compared
with plain grating.
3. I-shape type: Lighter, more economical and practical comparing
with plain grating.
4. Serrated I bar: Better Non-skid property & safety comparing
with I bar grating.

Installation of steel grating welding and mounting clips are
available two ways. For welded permanently fixed without
dismantling the site, such as equipment around the removal without
damaging convenient features.
Mounting Clip For various series of steel grating, with the card,
the next card M10 hexagon socket front bolt.
Welding fixing method is: in steel grating on each corner of the
first root of flat steel, weld length is not less than 20mm, height
not less than 3mm fillet.
The mounting clamps, each plate using at least four mounting clips
on the span larger plate preferably supporting material available
on a multi-install several.
In order to meet customer requirements, can provide stainless steel
In order installation folder, please specify the clip type,
quantity and materials.
Application of steel grating
Weld forged Steel Grating can be widely used in various industrial
buildings, such as metallurgy, building materials, power stations,
boilers, ship building, municipal construction, etc.
Steel grating advantage
Light weight, great load-bearing capacity, non-slip and safe,easy
installation, material-economic, sturdy and durable, ventilated,
easy to clean and attractive appearance.
