Model:T1,T2,T3,T4,T5,T6
Welding fixing: T1, T3, T5
Bolted fixing: T2, T4, T6
The width of treads is usually between 0.5m and 1m.

(1) The installation of step board is very simple and does not need complex installation;
(2) Good ventilation, daylighting, heat dissipation, explosion-proof and anti-skid performance;
(3) The high strength, light structure and durability of the step board;
(4) The maintenance is very simple and prevents dirt from accumulating.
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.
