Welded Steel Grating Introduction:

Welded steel grid plate is made of loaded flat steel and horizontal bar arranged according to certain distance between longitude and weft. It is welded on the high voltage resistance welder to form the original plate. After deep processing, such as cutting, cutting, opening and edge wrapping, it becomes the finished product required by customers.
Welded steel grid plate is also known as steel grid plate, the standard welded steel grid plate is the twisted square steel and a number of bearing flat steel into direct welding into the whole, welding using modern automatic piezoresistive welding production line, so as to form a good bearing capacity of open grid type structural plate.
Because of its good bearing capacity, excellent cost performance, simple installation characteristics, the welded steel grille has become the most widely used steel grille products.
Welded steel grates have become the standard and preferred platform for all kinds of industrial platforms. They are usually used as pavement, platform, cover plate and step plate.
In addition, the welded steel grates maximize light, air, liquid, and sound circulation and greatly reduce wind load compared to solid planks due to their open grid structure.
The bearing flat steel of welded steel grid plate is usually 3mm and 5mm thick flat steel, and "I" type flat steel and toothed flat steel can also be used. The width of bearing flat steel (that is, the thickness of steel grid plate) is from 20mm to 75mm. For the introduction of bearing flat steel, please refer to the type of bearing flat steel.
The spacing of welded steel grates bearing flat steels is usually 30mm or 40mm, and can also be 15mm, 20mm, 33mm, 60mm, etc.
The bar spacing is usually 100mm or 50mm, also can be 30mm, 33mm, 150mm, etc.
Thus constitute different series, a variety of specifications of steel plate, to meet the different load and other requirements.
According to customer's request, our factory can also manufacture any special specifications of welded steel grid.

Welded Steel Grating Specifications:

1, flat steel spacing of 30mm steel grid for the industrial field of the most widely used varieties.In the series of commonly used steel grates, it has the strongest resistance to surface impact.

2, flat steel spacing of 40mm steel grid for the most economic, the most portable varieties.In the case of minimum span, it is the most ideal choice.

3, flat steel spacing of 60mm, bar spacing of 50mm steel grid is designed for the application of mining and the development of varieties, it solves the problem of mineral splashing on the surface, often designated for mining processing plants, transfer stations, crushing system of the surface.

4, flat steel and bar are made of GB/T700 Q235, according to the agreement between the supply and demand, can also be made of other materials.

5. Flat steel is made of hot rolled flat steel or hot rolled or cold rolled steel strip after longitudinal shear.

6. The allowable deviation of flat steel size conforms to the provisions of Table 1 YB/T4001.1-2007.

7. Tooth flat steel is made of hot rolled flat steel or hot rolled or cold rolled steel strip after slitting and punching.The tooth size should not be less than 5 teeth per 100mm.

8, the section size and section moment of inertia of I - shaped flat steel.

Welded Steel Grating Application:

Widely used in petrochemical steel grid plate, power plant steel grid plate, water plant steel grid plate, sewage treatment plant steel grid plate, municipal engineering steel grid plate, sanitation engineering steel grid plate and other fields of platform, trestle trench cover, manhole cover, ladder, fence, fence, etc

Welded Steel Grating Advantages:

1. Save materials;2. Reduce investment;3, the construction is simple;4. Save time limit;5 durable;6. Modern style;7, light structure;8, prevent accumulation of dirt;9, reduce wind resistance;10 Simple design;11, ventilation, lighting, heat dissipation, explosion-proof, anti-skid performance is good and so on.

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.
