Welded Steel Grating Introduction
The toothed steel grid is also known as the anti-skid steel grid. The difference between the toothed steel grid and the ordinary steel grid is that the flat iron is the tooth shape, which can play a very good anti-skid ability, especially suitable for wet and slippery places, such as offshore oil production platform. The toothed steel grid because of its higher price is usually used to be able to be very good anticorrosive hot dip galvanized surface treatment. The toothed steel grates are made of high strength carbon steel, so that the steel grates have very high strength, strength and toughness are much higher than that of cast iron, can be used in wharves, airports and other large span and heavy load environment. The toothed steel grilling plate has the characteristics of large displacement of ordinary steel grilling plate, and the water leakage area reaches 83.3%, which is more than twice that of cast iron. The appearance of the silver line of hot dip galvanized steel grating plate is quite beautiful. Compared with cast iron, the steel grating plate has the characteristics of material saving and investment: large span and heavy load.

Welded Steel Grating Application:
Serrated steel grating is made up of one side is serrated flat steel welded together, has the strong ability of anti-skid, especially suitable for wet, satiny, also on production platform, etc., but its price is higher, please consider when purchasing cost, hot galvanizing surface treatment on saw blade steel case board, has a strong force of anti-rust, 30 years of free maintenance and free replacement.
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 The material:
Common flat steel: the general material material is Q235. Common models are generally 253, 255, 303, 305, 323, 325, 403, 404, 405, 503, 505, 605, 705 specifications.We mainly use the longitudinal shear flat steel, and a steel plate cut.Tooth flat steel: the same model and ordinary flat steel, the difference is that one side of the flat steel has uneven tooth marks, the main role is to prevent skid.
Type I flat steel: thick on both sides and thin in the middle.
Twist steel: also known as twisted square steel, there are generally 5X5 6X6 8X8 square steel, twisted bar.
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:
