Press-Locked Steel Grating – Common, Integral, Louver, Heavy Duty.
Press-Locked Steel Grating – Common, Integral, Louver, Heavy Duty for Building Facade, Platform, Stair or Shelf
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.
Two press-locked steel grating with different mesh sizes which people often use: 33 mm × 33 mm, 33 mm × 11 mm.
Press-locked steel grating features:
- Light weight. high bearing capability and high strength.
- Non-silp. anti-corrosion.
- Not easy to deform
- Beautiful appearance.
- Easy to install and remove.
- Extended the lifespan.
Press-locked steel grating Classification of serrations:
- Materials: low carbon steel and stainless steel.
- Surface treatment: galvanized, painted or powder coated.
- Surface type: smooth surface and serrated surface
- Serrated surface type:
- S1: Trapezoidal teeth on the bearing bar.
- S2: Trapezoidal tooth both on the bearing bar and cross bar with the highest non-slip performance. In this three types. it is most popular.
- S3: The non-slip tooth is applied to the connect components. It has the lowest non-slip performance.
Types of press-locked steel grating by insertion angles and insertion modes.
Press-locked steel grating 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.
