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.
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:
1: Trapezoidal teeth on the bearing bar.
2: Trapezoidal tooth both on the bearing bar and cross bar with the highest non-slip performance. In this three types. it is most popular.
3: 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.
According to the different insertion angles and insertion modes, it can be divided into four types: common type, integral type, heavy duty steel grating and louver steel grating.
