T1 Welded Fixing Without Nosing Stair Tread For Steel Ladder 40mm
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
0mm. For the flat steel with this center distance, the recommended
step plate width is 125, 165, 205, 245, 285 and 325 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

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 compression resistance 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.
