Welded Steel Grating Introduction

Welded Steel Grating also known as grid, steel grid plate or grid plate, is flat steel and twisted steel welded, steel grid durable, relative to other products more affordable, its main use in power plant platform, parking platform, maintenance platform, ditch cover and step plate and other aspects.
Also used in environmental protection equipment and sewage treatment and other aspects, Zhengyang steel grid is widely used in petrochemical, electric power, tap water, sewage treatment, port wharf, building decoration, shipbuilding, self-propelled parking lot, municipal engineering, sanitation engineering and other fields platform, walkway, trestle, trench cover, manhole cover, ladder, fence and so on.
The gap width between the grid bars can be set according to the way of cleaning dirt and the requirements of the water pump. The gap between the manual cleaning grid is generally 16 ~ 25mm.
The grille before the sedimentation tank or sedimentation tank is generally 15-30mm, and the maximum is 40mm.
There are three kinds of commonly used mechanical slag cleaning equipment, that is, chain type, mobile type and wire rope traction type grid cleaning machine.
According to the different size of the grid spacing, the grid is divided into coarse grid, medium grid and fine grid 3 categories.
According to the grille slag cleaning method, there are three kinds of artificial grille, mechanical grille and hydraulic scavenging grille.
According to the different characteristics of the grid structure, it can be divided into grasping rake type, circulating type, arc type, rotary type, drum type, rotary type, tooth rake type and step type and other forms.
Grating equipment is generally used in the inlet channel of sewage treatment or the entrance of the pumping station collection tank. The main role is to remove large suspended or floating objects in sewage, to reduce the processing load of the subsequent water treatment process, and to protect the pump, pipeline, instrument and so on.
When the amount of intercepted gate slag is greater than 0.2m3/d, mechanical slag cleaning is generally adopted.
When the gate slag quantity is less than 0.2m3/d, manual slag cleaning or mechanical slag cleaning can be adopted.

Welded Steel Grating Specifications

Special steel grating for the tower

Flat steel specifications should be used: 25*4 25*5 30*4 32*5 40*4 40*5

Flat steel spacing should be used :30mm, 40mm

Cross bar should be used: 6mm 8mm

The bar spacing should be: 50mm, 100mm

Welded Steel Grating Advantages:

1.Ventilated, breathable, in rain and snow weather, the platform is not easy to snow, save manual cleaning.
2.The steel grating adopts toothed flat steel to have more anti-slip effect than the steel plate, and it is safer to use.
3.The steel plate is less than the steel plate, and the price is lower than the steel plate.

Welded Steel Grating Process:

The process design of steel grid plate is to arrange the material according to the geometrical information of the sheet according to the size of the original plate, and the ultimate goal is to make the material cutting plan take into account the maximum utilization rate of the material and higher production efficiency.
 

The principle of steel grid process collocation mainly has the following aspects:
1, all the full plate size or more than the full plate size of the steel grid are in accordance with the length of the priority collocation, collocation size as little as possible and unified, length range control in 5-7 meters.
2. A small number of narrow plates can be arranged in order of width from large to small or from small to large, and then can be combined together in parallel according to length.
3. When the width overflows, the raw material cross bar is used for edge welding, instead of welding another plate.
4, double rod welding machine each pressure welding 2 bars, can not appear odd circumstances.
5, between the board and the board to retain the sawing size, if not enough need to leave a cross bar.
6, for a set of drawings need to be strictly classified.
If multiple drawings are more than 200 square meters, they need to be matched together. If less than 200 square meters, it can be considered to match them with small size drawings.
7, for the special-shaped steel grid, need to consider decomposition and docking, in order to achieve the most economical material.
8, for flat steel spacing 60 mm plate can be used 30 mm spacing comb clip for raw material production.

Welded Steel Grating installation:

The connection mode of steel grid plate is fixed and installed with buckle connector, which is composed of three parts.
