Welded Steel Grating Introduction

Welded steel grid plate is made of flat steel in accordance with a certain distance and cross bar (twisted square steel, square steel, round steel, flat steel, etc.), and spot welded into a kind of iron and steel products with a square grid in the middle, the bar is generally used after twisted square steel.
The steel grid is generally made of carbon steel, and its appearance is hot dip galvanized, which can prevent oxidation.
It can also be made of stainless steel.
Welded steel grid plate features: 1, strength, light structure: solid grid pressure welding structure so that it has high bearing capacity, light structure, easy to hoisting and other characteristics
2, beautiful appearance, durable: hot dip zinc surface treatment makes it has a very good anti-corrosion ability, the surface luster is beautiful.
3, ventilation, lighting, heat dissipation, explosion-proof, anti-skid performance is good.
4, no dirt, no rain and snow, no water, self-cleaning, easy to maintain

Welded Steel Grating Specifications

(1) the distance between the center of the welded steel grating plate and the flat steel plate: to distinguish according to the series: Series 1 is 30mm;

Series 3 is 60mm.
(2) the distance between the center bars of welded steel grille plate: series 1 is 100mm, series 2 is 50mm.
Other specifications can be customized.
(3) welded steel grating plate flat steel: the material is Q235 or stainless steel, there are ordinary plane type, anti-skid tooth type and section I type.
Common specifications are 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, 100*10 and so on.
(4) welded steel grating plate bar: round steel, twisted square steel, square steel or hexagonal steel made of Q235 or 304 stainless steel.
Twisted square steel is made by drawing and twisting the square die, and its common specifications are 5*5, 6*6, 8*8mm, etc.

Welded Steel Grating Application:

Light chemical industry, iron and steel industry, fine refinery, airport engineering, petrochemical waste treatment
Mining and refining water plant machinery chemical food processing power plant sewage treatment
Textile, chemical industry, aquaculture, municipal engineering, paper industry, port engineering, fertilizer industry
Marine engineering, construction, oil, chemical, pharmaceutical industry, shipbuilding, transportation

Welded Steel Grating Advantages:

1. Can be added in the peripheral welding kick plate (side plate), decorative plate guard plate, install fittings and other accessories.
2. Flat steel with different specifications from the loading flat steel is used to wrap the edges, or Angle steel, channel steel, square pipe, etc.
3. Handles and hinges can be installed on the platform steel grid plate that needs to be moved or opened frequently.
4. The cladding welding standard of the platform steel grid plate is: one for every five series 1;
Series 2, one for every four welds;
Series 3 welds one per three.
The weld shall be a single fillet welding of not less than 3mm, and the weld length shall be 20mm.

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.
Hot Dip Galvanized Steel Grating Package delivery:
