Steel grating production standards
In addition, the United States, the United Kingdom, Australia and New Zealand also have their own standards. Steel standards follow GB700-88, GB1220-92.
The grid indicates the processing method:
Hot dip galvanizing, cold galvanizing, spray painting, soaking in anti-rust oil, no treatment (general stainless steel does not need treatment).
The production standards of mesh grids are China's YB4001-1991, YB/T4001-1998 standards, and can also be produced in accordance with British BS4592-1-1995 and American ANSI/NAAMM (MBG531-88) standards.
How to make a mesh grid
The pressure-welded steel grating is made of load-bearing flat steel and cross bars arranged at a certain distance in longitude and latitude. It is welded into the original plate using 200 tons of hydraulic resistance welding automation equipment. It is processed into the product required by the customer after cutting, drilling, hemming and other processes.
Spacing between loaded flat steels: the center distance between two adjacent loaded flat steels, commonly used are 30MM and 40MM.
Crossbar spacing: The center spacing between two adjacent crossbars is usually 50MM or 100MM, and can be produced according to customer requirements.
Compared with patterned steel plates and other gratings, steel gratings have the following advantages:
Material saving: The most material-saving method under the same load conditions. Correspondingly, the material of the supporting structure can be reduced.
Reduce investment: Save materials, save labor, save construction period, and eliminate cleaning and maintenance.
Simple construction: Use bolt clamps or welding to fix the pre-installed supports, and it can be completed by one person.
Save construction period: The product does not require on-site reprocessing and installation is very fast.
Durable: It is hot-dip galvanized for anti-corrosion treatment before leaving the factory, and has strong resistance to impact and heavy pressure.
Modern style: beautiful appearance, standardized design, ventilation and light transmission, giving people an overall smooth modern feeling.
Light structure: less material is used, the structure is light, and it is easy to hoist.
Anti-dirt accumulation: Does not accumulate rain, ice, snow and dust.
Reduce wind resistance: Due to good ventilation, wind resistance is small in strong winds, reducing wind damage.
Simple design: No need for small support beams, simple structure, simplified design; no need to design detailed drawings of steel gratings, just indicate the model, and the factory can design the layout plan on behalf of the customer.
Good ventilation, lighting, heat dissipation, explosion-proof, and anti-slip properties: Acid and alkali corrosion ability: 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.
