T1 Welded Fixing Without Nosing Stair Tread For Steel Ladder 30mm Bearing Bars Pitch

Introduction to technical parameters of step plate grating

The steel grating of this model adopts the welding fixed installation method. The center distance of the load flat steel is 30mm. For the flat steel with this center distance, the recommended step plate width is 125, 155, 185, 215, 245, 275 and 305 mm, and the center distance of the cross bar is 10cm.

According to the cross-sectional area of the flat steel, the recommended step plate length rules are as follows:

If the load flat steel section of the step plate is 25mm * 3mm, the recommended step plate length is 550mm;
If the load flat steel section of the step plate is 25mm * 5mm, the recommended step plate length is 900mm;
If the load flat steel section of the step plate is 32mm * 5mm, the recommended step plate length is 1300mm;
If the load flat steel section of the step plate is 40mm * 5mm, the recommended step plate length is 1600mm;

The allowable error of tread plate width is: - 3mm to 3mm, and the allowable error of length is 0-3mm.

The main application scenarios of step steel grating are as follows:

Treads are widely used in power plants, water plants and other factories, as well as platforms and walkways in the fields of municipal engineering and environmental sanitation engineering, as well as ground platforms in large places such as cinemas, visiting platforms and parking lots.

Main performance of steel ladder step plate grating:

The installation of the step board is very simple. The welded fixed interface is directly adopted. It is required to have good lighting performance in the plant. The step board designed by this grid has very good ventilation and light transmission effect, high strength, light structure, corrosion resistance, no accumulation of rain and snow, durability and no enclosure. It has impact resistance and good compressive performance in the plant.
