Press locked serrated stair treads

Serrated press-locked steel grating is made of low carbon steel or stainless steel. With the features of high strength, high bearing capacity, non-slip, anti-corrosion, anti-rust, high security, do not accumulate rain, snow and dust, simple and beautiful and easy to install and remove, serrated press-locked steel grating is widely used in industrial, commercial and civil constructions as floors, platforms, entrance ramp, walkways and different types of ladders, such as straight ladder and spiral ladder.

Press-Locked Grating is specified due to its clean, smooth look as well as supporting the same loads as welded bar grating though not recommended for rolling loads. Press-Locked is formed using tremendous hydraulic pressure to bond the two close-tolerance slotted bars together, permanently locking the cross bars into the notched bearing bars. Press-Locked grating is fabricated to meet project requirements. Press locked bar grating is an extremely versatile product that can be used in a wide range of industrial applications. It offers the advantage of superior lateral support, particularly when using press-locked steel bar grating (as opposed to the aluminum version). What's more, press locked-bar grating is durable and very easy to maintain, making it a reliable and long-term grating solution.

The Uses of Press-Locked Bar Grating

1. Stair treads

2. Security screens in commercial buildings

3. Municipal engineering as tree covers, trench covers and drainage covers

4. Platforms

5. Walkways in industrial factories or parks

6. Modular mezzanine structures

7. Bridges for vehicles and pedestrians

8. Marine industries as working platform

9. Suspended ceiling


1. Panel width to be 6mm-16mm

2. Panel gaps length to be 10mm

3. Banded bars are welded 5mm fillet seal weld to every load bar.
