In addition to being used in trenches and platforms, FRP gratings can also be used as stair steps. We call them stair treads.

The commonly used pedals are made of 38*38*25 and 38*38*38 FRP gratings. In general, the stairs are narrow, using 38*38*25 specifications, such as 50-80cm width; the staircase width is greater than 1m, it is recommended to use 38*38*38 specifications. The width of the pedal is generally 20-25cm, which is better to be in the position of the side, which is more beautiful. For example, the pedal width is 5 grids, 6 grids, and the like.

When the pedal is fixed with the channel steel on both sides, it is better to use bolts with a diameter of 8mm or more. The pedals are supported by angle steel, and the thickness of the angle steel is recommended to be more than 5mm. The vertical distance between the pedal and the pedal is generally 25-30cm, which can be adjusted according to the actual situation. Some customers also use the FRP pattern cover as a pedal, mainly to prevent the staff from falling down from the top when the staff goes up and down the stairs, which affects the work of the decentralized personnel. .
