Step steel grid is a kind of steel stair for platform stair. According to the installation method, there are generally two types of welding and screw fixing. Welding directly to the keel does not need to add step steel grid. It is more economical and durable but it is not the same as disassembly. Bolted step steel grids need thickened side plates on both sides. Holes are punched in the side plates. The installation is directly bolted and can be recycled and reused. Customers can customize according to their actual needs, and can be made into any size with any type of steel grating to match the corresponding staircase. However, from an economic point of view, we recommend that we use the recommended size whenever possible.

How to choose the step steel grid plate model: The main step steel grid plate models are (T1 T2 T3 T4) four middle models, which are mainly divided according to whether there are front shields and perforated side panels, which are mainly based on customer use Requirements to be determined.

You can choose through the following methods: 1. If there are many people going up and down the stairs, you should use a front shield, otherwise you can not add a front shield to reduce your costs. 2. Is it fixed by screws or welding during installation? The rear side plate with perforation must be added for bolt fixing, and the thick side plate does not need to be directly welded.

Overview of Step Steel Grating: Step Steel Grating is also called Stair Step Steel Grating, Steel Ladder, Steel Ladder. It is a type of staircase for steel grating for platform. Depending on the installation method, there are two types of welding and bolting, which are directly welded to the keel, without the need to add side plates of steel grating. Durable but not easy to disassemble. Bolted step steel grids need thickened side plates on both sides. Holes are punched in the side plates. The installation is directly fixed by bolts, which can be recycled and reused. Customers can customize it according to their actual needs. Any type of steel grating can be used to create various sizes to match the corresponding stairs.

Step steel grid plate model: welding fixed: ST1, ST3, ST5. Bolt fixing: ST2, ST4, ST6.

Marking and tolerance of step steel grating: ST4 -— (RA325 / 30) ST4—model of step steel grating, model of RA325 / 30 steel grating. Tolerance of step steel grating: width W ± 3mm, length L-3mm.

Recommended length of step steel grating: 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 use the modulus width as much as possible (series 1, 125, 155, 185, 215, 245, 275, series 2 125, 165, 205, 245, 275 mm, etc.) as a multiple of 100 mm (such as 500, 600, 700, 800, 900, 1000, 1200mm, etc.).
