T1 Welding Galvanized Steel Stair Treads Serrated Stair Treads
T1 Welding And Fixing Non Front Guard And Non Slip Steel Ladder Step Plate Bearing Bar At 40mm Pitch
The introduction of the T1 toothed ladder step grating plate
The step steel grating of this model is fixed by welding. The center distance of the load flat steel is 40mm. For the flat steel with this center distance, the recommended step plate width is 125, 165, 205, 245, 285 and 325mm, and the center distance of the cross bar is 10cm.
| bearing bar pitch(mm) | 40 | 40 | 40 | 40 | 40 | 40 |
| grating width(mm) | 125 | 165 | 205 | 245 | 285 | 325 |
The recommended step plate length rules according to the cross-sectional area of the flat steel are as follows:
If the load flat steel section of the step plate is 25mm * 3mm, the recommended step plate length is 450mm;
If the load flat steel section of the step plate is 25mm * 5mm, the recommended step plate length is 750mm;
If the load flat steel section of the step plate is 32mm * 5mm, the recommended step plate length is 1200mm;
If the load flat steel section of the step plate is 40mm * 5mm, the recommended step plate length is 1500mm;
| bearing bar(mm*mm) | 25*3 | 25*5 | 32*5 | 40*5 |
| grating lenght(mm) | 450 | 750 | 1200 | 1500 |
The allowable error of tread plate width is: - 3mm to 3mm, and the allowable error of length is 0-3mm.

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.
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.
