The steel grating is a kind of iron and steel products with flat steel in accordance with a certain spacing and cross-bar (twisted square steel, square steel, round steel, flat steel, etc.) and is welded into a steel box with a square lattice in the middle. The board is mainly used for ditch covers, wire mesh fence, steel platform boards, steel ladders, animal cage, etc. Crossbars generally use twisted square steel. Steel gratings are generally made of carbon steel and hot-dip galvanized on the outside to prevent oxidation. Can also be made of stainless steel. The steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
Steel grating production standards
China YB4001-1991, YB/T4001-1998, YB/T4001.1-2007 standards (China is the latest version of steel grating standard in 2007); In addition, the United States, Britain, Australia and New Zealand also have their respective standards, also can be in accordance with the British BS4592 -1-1995 and the United States ANSI/NAAMM (MBG531-88) and other standards production. Steel standards in accordance with GB700-88, GB1220-92 implementation.
Steel grating surface treatment methods: hot-dip galvanized, cold galvanized, spray paint, immersion anti-rust oil, no treatment (general stainless steel without treatment).
Steel grid plate manufacturing method
The pressure-welded steel gratings are arranged by a certain distance and latitude and longitude between the load flat steel and the cross bar, and are welded to the original plate with 200 tons of hydraulic resistance welding automation equipment, and are processed through the processes of cutting, opening and wrapping to obtain the products required by customers.
Loaded flat steel spacing: The center distance between two adjacent load flat steels, commonly used 30MM, 40MM two.
Crossbar spacing: The center-to-center spacing between two adjacent crossbars is typically 50mm, 100, two, and can be produced on request.
Superiority
Material saving: The way to bear the least material under the same load conditions, and accordingly, the material of the support structure can be reduced.
Reduce investment: save materials, save labor, save time, eliminate cleaning and maintenance.
The construction is simple: on the pre-installed support, it can be fixed with a bolt clamp or fixed by welding, and one person can complete it.
Save time: The product does not need to be reprocessed on the spot and it is installed very quickly.
Durable: Hot dip galvanized anti-corrosion treatment before delivery, strong resistance to impact and weight.
Modern style: beautiful appearance, design specifications, air and light transmission, giving people an overall smooth and modern experience.
Lightweight structure: less material, light structure, and easy to lift.
Anti-contamination: No accumulation of rain, snow and dust.
Reduce wind resistance: Due to good ventilation, wind resistance in case of large winds reduces wind damage.
The design is simple: no need for small beams, simple structure, simplified design; no need to design the steel grating details, only specify the model, the factory can design the layout diagram on behalf of customers.
Ventilation, lighting, heat dissipation, explosion protection, anti-slip performance: Acid and alkali corrosion resistance: In the range of PH 6 to PH 12.5, a stable protective film is formed on the surface of the zinc layer, and the corrosion resistance is good.
Steel grating use
1. It is used as a platform for gangways, passageways, pump rooms and engine rooms of various ships.
2, used as a bridge, such as the side of the railway bridge, overpasses, etc., walkway paving.
3. It is used as a platform for oil production plants, car washes and high-altitude towers.
4. It is used as a parking lot for municipal projects, a fence for large venues and buildings, road fences, drainage manhole covers for roads, and ditch covers.
Steel gratings are suitable for alloys, building materials, power stations, boilers. shipbuilding. Petrochemical, chemical and general industrial plants, municipal construction and other industries have the advantages of air and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean and easy to install. Xinqiao Brand Steel Grating has been widely used in various industries at home and abroad. It is mainly used as an industrial platform, ladders, handrails, access floors, railway bridge side roads, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers The three-dimensional parking lot, fences of offices, schools, factories, enterprises, sports grounds, and garden villas can also be used as exterior windows of private houses, balcony guardrails, and guardrails of highways and railways.
As a new type of engineering material, steel gratings are mainly used as platforms, trestle bridges, bridges, highway guardrails, trench covers, fences, and gates in such fields as metallurgy, energy, marine, municipal, petrochemical, transportation, building materials, and national defense. At present, China needs about 270,000 tons of steel grating annually. Therefore, the market prospect of steel grating is very broad.
Steel gratings have been widely used in hundreds of factories at home and abroad, such as power plants, chemical plants, oil refineries, steel mills, machinery manufacturing plants, paper mills, cement plants, pharmaceuticals, and food processing plants.
