Grating (Grille Board), also known as steel mesh panels, because of regional differences, Southerners used to call grating, northerners habit called the steel grating. General state collectively referred to as steel grating.

Flat steel grill plate is carried out in accordance with a certain distance and rail staggered, and welded into the middle of a steelworks with a square lattice, mainly used for drain cover, steel platform board, stepping ladders board. Rail commonly used twisted square steel.

Grating generally use Q235 low carbon steel, galvanized appearance, can serve to prevent oxidation. It may also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof properties.

Grill plate production standards, China is YB / T4001-1998; in addition the United States, Britain, Australia and New Zealand also have their own standard steel standard according to GB700-88, GB1220-92..

Grating tooth surface can be washed in order to increase slip resistance. Flat type I may also be flat steel production.

Grill plate production methods: pressure welding machine and manual production of two high-pressure resistance pressure welding machine pressure welder, robot automatically on the flat horizontal crossbar evenly through strong welding power and force. rail bonding into the flat, solder joint can be obtained solid, high stability and strength of high-quality steel grating. handmade steel grating is the first punch in the flat, and then the crossbar into the hole spot welding, steel bar and the gap will exist, and each contact point can not be welded, the welding is not strong, the strength decreased.

Grating Features:

1. High-strength, light structure: strong pressure welding grid structure with high carrying it, light structure;

2. Ease of loading and other characteristics;

3. appearance, durable: hot-dip zinc surface treatment it has a very good corrosion resistance;

The surface gloss appearance;

5. ventilation, good lighting, cooling, explosion, skid resistance; against product contamination;

Grating Product Specifications:

1. The vertical bar spacing: 30-60 (mm);

2. bar spacing: 50-100 (mm);

3. Width: 20-60 (mm);

4. thickness: 3-50 (mm);

Grating uses: petrochemical, municipal engineering, port engineering, mechanical engineering, power plant water, iron and steel industry, manufacturing, food processing industry and many other industries have been widely used.
