Different Fabrication

- Welded steel grating
- Press-locked grating
- Swage locked grating
- Riveted grating
- Close mesh steel grating

Welded steel grating is the most popular type among all types of steel grating, also called metal open bar grating. It is also the most widely used type.

Welded steel grating is produced through automatically resistance welded. The bearing bars and cross bars are resistance welded under high heat and pressure to form a permanent joint. This technology can not only ensure the rugged structure of welded steel grating, but also can retain a smooth and flat surface, which is easy and free to walk.

Welded steel grating can be made of various materials, such as carbon steel bars, aluminum steel bars and stainless steel bars.

The bearing bar has two different types according to the surface: smooth bearing bar and serrated bearing bar. Smooth surface steel grating, also called plain steel grating, is more popular than the serrated surface steel grating. But the serrated steel grating have better skid resistance property than the smooth surface.

Press-Locked Steel Grating also can be called pressure locked grating, it is made of low carbon steel or stainless steel. With the performance of high bearing capacity, non-slip, anti-corrosion and easy to install and remove, pressure locked grating is widely used for ceilings, platforms, floors, fence and all kinds of cover in the factories, civil and commercial buildings.

The Most Popular Pitch Size for Press Locked Steel Grating is 33mm x33mm and 33mm x 11mm.

                         Popular mesh size 33x33mm (C to C)                                                           Popular mesh size 33x11mm (C to C)  

Common type:

• After the grooving of bearing bar, the cross bar press locked and molded.
• Maximum machining height of common steel grating is 100 mm, the length of steel grating is less than 2000 mm.
• The standard height of bearing bar: 20 mm to 170 mm.
• The standard thickness of bearing bar: 2 mm, 3 mm, 4 mm, 5 mm.
