How to install and fix galvanized steel bar grating

Stepping steel grating installation and fixed treads are also known as stair treads, steel treads, and steel ladders. It is a kind of staircase used for the platform of the steel grid plate. According to the installation mode, there are generally two types of welding and bolt fixing, which are directly welded to the keel, and do not require the side plate of the step plate, which is relatively economical and durable but It is difficult to dismantle and the thick side plates are needed on both sides of the bolted tread plate. The side plate is drilled and the installation is directly fixed by bolts, which can be recycled and reused. Customers can customize according to their actual needs, can use any type of steel grating to create a variety of sizes to match the appropriate stairs.

Stepping plate model welding fixed: ST1, ST3, ST5
Bolt fixing: ST2, ST4, ST6
The width of the tread board is usually between 0.5 meters and 1 meter.
Step board markings and tolerances
ST4—(RA325/30) ST4—step plate type, RA325/30 steel grating type step plate tolerance: width W±3mm, length L-3mm.
3 characteristic use

(1) The installation of the tread board is very simple and does not require complicated installation;
(2) ventilation, lighting, heat dissipation, explosion-proof, anti-skid performance;
(3) The high strength, light structure, and longevity of the tread board;
(4) durable and beautiful appearance, beautiful surface gloss;
(5) Maintenance is very simple and dirt-proof.
The purpose of the tread board is very extensive, and it is widely used in power plants, water plants and other factories, as well as platforms such as municipal engineering and sanitation engineering, walkways, theaters, visiting platforms, parking lots and other large-scale ground platforms.
4 recommended length

Recommended ladder pedal width (based on 5mm thick flat steel)
T1 to T4 30mm pitch 125 155 185 215 245 275 305
T1 to T2 40mm pitch 125 165 205 245 285 325
T3 to T4 40mm pitch 115 155 195 235 275 315
T1 to T2 60mm pitch 185 245 305
T1 to T2 60mm pitch 155 215 275
From an economic point of view, it is recommended to adopt a modulus width (series 1, 125, 155, 185, 215, 245, 275, series 2, 125, 165, 205, 245, 275mm, etc.) as 100mm multiples (eg, 500, 600, 700, 800, 900, 1000, 1200mm, etc.).
