Stair tread steel grating

Stair tread steel gratings are processed from steel gratings (grill treads are cross-arranged with flat steel according to a certain spacing and crossbars, 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 and electro-galvanizing.

Characteristic:

(1) The installation of stair tread steel gratings is very simple and does not require complicated installation;

(2) Good ventilation, lighting, heat dissipation and anti-skid performance;

(3) High strength, light structure and durability of stair tread steel gratings;

(4) The maintenance is very simple and prevents the accumulation of dirt.

Type:

(1) According to the installation of stair tread steel gratings, it is divided into welded fixed stair tread steel gratings and bolted stair tread steel gratings . Among them, the stair tread steel grating plate fixed by welding is the steel grating plate, and the stair tread steel grating plate fixed by bolts needs to add 65X5mm flat steel to the steel grating plate as the side plate.

(2) According to the anti-skid requirements of stair tread steel gratings, it can be divided into two types: stair tread steel gratings with front guards (checker plate or strip steel) and stair tread steel gratings without front guards. T325/30/100 (applicable to stair tread steel gratings with a width greater than 215mm but not greater than 305mm) T255/30/100 ((applicable to stair tread steel gratings with a width greater than 215mm but not greater than 305mm) stair tread steel gratings for guards.
