Stair Tread Grating
Stair step grid plate, also known as stair tread plate, steel ladder tread plate, ladder pedal, is a type of stair plate for the channel, and its device method is of two types: welded joint and bolted joint.
The stair step grating plate is made of steel grating plate (the steel grating plate is arranged by flat steel at a certain interval and cross bar, and welded into a steel product with a square lattice in the middle). The surface of the product is generally treated with hot-dip galvanizing or electro-galvanizing.
1. According to the installation of the ladder pedal, it is divided into a welded fixed ladder pedal and a bolt-fixed ladder pedal. Among them, the welded fixed ladder pedal is a steel grating, and the bolted ladder pedal needs to add 65×5mm flat steel as the side plate to the steel grating.
2. According to the anti-skid requirements of the ladder pedal, it can be divided into two types: the stepped pedal with the front guard plate (tread plate or strip) and the ladder pedal without the front guard plate. T325/30/100 (applicable to ladder pedal width greater than 215mm not greater than 305mm) T255/30/100 ((applicable to ladder pedal width greater than 215mm not greater than 305mm)
