Steel Grating

Classification of stepping steel gratings

Various types of steel gratings are placed on the ground.

Treads, also known as stair treads, steel ladder treads, and ladder treads, are a kind of stair plate used for platforms. There are two types of installation methods: welded connection and bolt connection. The welded fixed tread can be directly Welded to the ladder beam. Model Welding Fixing: ST1, ST3, ST5 Bolting Fixing: ST2, ST4, ST6 The width of the pedals is usually between 0.5 m and 1 m. Features (1) The installation of the treadle is very simple and does not require complicated installation; (2) Good ventilation, lighting, heat dissipation, explosion-proof and anti-skid performance; (3) The treadmill has high strength, light structure, and durability; (4) ) is very easy to maintain and prevent the accumulation of dirt.

Category: Anti-skid treads Raw material: toothed flat steel, the general material is Q235, the difference between toothed flat steel and ordinary flat steel is that there are uneven tooth marks on one side of the flat steel. (Mainly because of anti-slip. We mainly use slitting flat steel, and steel plate cutting) Twist steel: also called twisted square steel, generally 5x5 6x6 8x8 square steel, twisted steel bar. Stair treads Stair treads are deep-processed products made of steel grating plus anti-skid strips and side panels. It is mainly used for stepping on steel ladders, so it is usually called a stair tread, abbreviated as a ladder tread. Specifications of stair treads: Stair treads need to be manufactured into various sizes to match the corresponding stairs, but from the perspective of economy and safety, we recommend you to use the following specifications: T325/30/100 (applicable to the width of stair treads More than 215mm but not more than 305mm) T255/30/100 ((suitable for stair treads with a width greater than 215mm but not more than 305mm) steel ladder treads Steel ladder treads are processed from steel grating (steel grating is made of flat steel According to a certain spacing and cross bars, they are arranged in a cross, and welded into a metal product with a square lattice in the middle). The surface of the product is generally treated with hot-dip galvanizing and electro-galvanizing. According to whether there is a front guard plate and the connection with the ladder beam It can be divided into four forms, expressed as T1, T2, T3, T4. (1) According to the installation of steel ladder treads, it is divided into welded fixed ladder treads and bolted ladder treads. The welded fixed ladder treads are steel grids Ladder treads fixed by bolts need to add 65X5mm flat steel to the steel grating as side plates. (2) According to the anti-skid requirements of steel ladder treads, it can be divided into ladder treads with front guard plates (checker plate or strip steel). There are two types: steel ladder treads without front guards. For safety reasons, customers are advised to use steel ladder treads with front guards.
