Different classifications of stair tread steel grating
Stair tread steel gratings, also called grating steps, are made of low carbon steel or stainless steel. It is one of the most widely used and popular types of steel gratings. With the features of high strength, high bearing capacity, wear resistance, resistance to extreme temperature wind and rain, non-slip, anti-corrosion, beautiful and easy to install and remove extend the lifespan, stair tread steel grating is widely used as different types of steel ladders in the factory, school, park, stadium, civil and commercial buildings.

Different classifications of stair tread steel grating
According to the different production methods, straight stair tread steel grating can be divided into welded stair tread, press-locked stair tread, swage-locked stair tread and riveted stair tread.
Welded stair tread is the most widely used type in most industrial and commercial applications, it is easy to install.
Press-locked stair tread and swage-locked stair tread can provide higher strength, and when the surface type is serrated surface, it is more safety.
Riveted steel stair tread have a greater load carrying capacity and greater walking comfort
- According to the different types of surface, straight stair tread steel grating can be divided into smooth stair tread and serrated stair tread
- According to the different shapes of stair, stair tread steel grating can be divided into straight stair tread steel grating and spiral stair tread steel grating
- Besides the checker plate and abrasive nosing, these are also other types.
Packaging
- Strap packing: Generally used for neat press locked steel grating.
- Pallet packing: Generally for the press-locked steel grating which need to export and load in container.
- Screw rod fixation: Use four screw rods through the mesh and fixed with screws.
