T1 T2 T3 T4 T5 T6 Galvanized Steel Stair Treads Free Sample
1)The treads are called "pedal ladders, steel ladders, stairs treads" is manufactured by processing steel grating ,steel grating is made by flat steel and bars according to spacing cross-arranged and welded into the middle with square mesh )
2)The surface of the treads generally with hot dip galvanized or cold galvanized.
3)Classification:according to the front fender and ladder beam connection express as T1, T2, T3, T4, T5, T6
T1 front fender of (fixed welding)
T2 front guard plate (bolted)
T3 checkered plate front fender (welding fixed)
T4 checkered plate before the guard plate (bolted)

Recommended as far as possible from the economic point of view, the modulus width (Series 1 125,155,185,215,245,275, Series 2 125,165,205,245,275 mm) 100mm multiple of the length (such as 500,600,700,800,900,1000,1200 mm).
Treads Tolerance: width W ± 3mm, length L-3mm.
The treads (ladder pedal), type:
(1) According to the ladder pedal installed into welding fixed ladder pedal pedal bolt ladder. The welding fixed ladder pedal that steel grating, bolted ladder pedal steel grating plus 65X5mm flat steel as the side panels.
(2) have the front fender (checkered plate or bars) ladder pedal and the front fender ladder pedal anti-slip requirements can be divided into two ladder pedal. T325/30/100 (applies to the ladder tread width is greater than 215mm is not greater than 305 mm) T255/30/100 ((applied to the the ladder tread width greater than 215mm less than 305mm) Note: For security reasons, it is recommended that customers using with front shield ladder treads.
