Steel stair treads need to be manufactured in various sizes to match the corresponding stairs, but from the perspective of economy and safety, we recommend that you adopt the following specifications:
T325/30/100 (applicable for ladder tread width greater than 215mm but not greater than 305mm)
T255/30/100 ((applicable for ladder tread width greater than 215mm and not greater than 305mm) width length
Under normal circumstances, the width of the stair treads is not greater than 305mm, and the length of the stair treads is not greater than 1000mm.
