ISO9001 Step Board Galvanized Steel Grating Walkway Pressure Resistance Welding
Heavy Duty Galvanized Steel Grating Walkway Trench Cover Stair Treads Steel Grating
Steel Grate Stair Treads Introduction
Stair steel grid board also called stair step board.
Stair steel grid plate is made of steel grid plate processing (steel grid plate is made of flat steel in accordance with a certain distance and cross bar arrangement, and welded into the middle with a square grid of steel products).
The surface of the product is generally treated with hot dip galvanizing and electric galvanizing.
(1) According to the installation of the stair steel grid plate, it is divided into the welded fixed ladder pedal and the bolt fixed ladder pedal.
The welded and fixed ladder pedal is the steel grid plate, and the bolted ladder pedal needs to add 65X5mm flat steel to the steel grid plate as the side plate.
(2) according to the anti-skid requirements of the stair steel grid plate, it can be divided into two kinds: the ladder pedal with front guard plate (pattern plate or bar steel) and the ladder pedal without front guard plate.
T325/30/100(For step width greater than 215mm but not greater than 305mm) For safety reasons, it is recommended that the customer use the step with front guard.
