Special steel grating for sewage treatment plant

The steel grating is an open steel member which is composed of bearing flat steel and cross bar according to a certain spacing and fixed by welding or press locking; The cross bar is generally made of twisted square steel, or round steel or flat steel. The material is divided into carbon steel and stainless steel. Steel grating is mainly used for steel structure platform plate, trench cover plate, steel ladder step plate, building ceiling, etc.

1. Ordinary hot galvanized grid plate

After the bearing flat steel is punched, the cross bar flat steel is press locked and formed. The * large processing height (the height of flat steel) for the production of ordinary grating plate is 100mm. The length of grating plate is usually less than 2000mm.

2. Integral hot galvanized grid plate

The bearing flat and the cross bar flat have the same height and the groove depth is 1 / 2 of the bearing flat. It is also called semi plug-in steel grating. The height of the grating plate is not more than 100mm. The length of grating plate is usually less than 2000mm.

3. Sunshade type hot galvanized steel grating

The load-bearing flat steel is slotted at 30 ° or 45 ° and the slot bar flat steel is slotted and press locked. According to different needs, other spacing and specifications of grid plates can be handed over. Ordinary carbon, stainless steel, aluminum and other materials can be used. The height of grating plate is less than 100mm.

4. The heavy-duty hot-dip galvanized grid is a multi load-bearing steel grid, which is engaged by the high flat mesh and the cross bar flat mesh, and pressed under the pressure of 1200 tons. It is suitable for span and high load-bearing occasions.

The steel grid is made of load flat steel and cross bars arranged at a certain distance longitude and latitude, welded into the original plate with 200 tons of hydraulic resistance welding automation equipment, and processed into the product required by the customer through cutting, opening, edge wrapping and other processes.

Spacing of load-bearing flat steel: the center distance between two adjacent load-bearing flat steel is usually 30mm and 40mm.

Cross bar spacing: the center spacing between two adjacent cross bars is usually 50mm and 100mm, which can be produced according to customer requirements.

Compared with checkered steel plate and other grids, steel grid has the following advantages:

Material saving: the method of saving materials under the same load conditions can correspondingly reduce the materials of the supporting structure.

Reduce investment: save materials, labor, construction period and cleaning and maintenance.

Simple construction: fixed with bolt clamp or welded on the pre installed support, which can be completed by one person.

Save time: the product does not need to be reprocessed on site, and the installation is very fast.

Durable: hot dip galvanized anti-corrosion treatment before delivery, strong impact resistance and heavy pressure resistance.

Modern style: the appearance is beautiful, the design is standard, the ventilation is transparent, and the overall smooth modern feeling is given.

Light structure: less materials, light structure and easy to lift.

Anti Dirt: no rain, snow and dust.

Reduce wind resistance: due to good ventilation, the wind resistance is small in case of strong wind, so as to reduce wind damage.

Simple design: no small support beam, simple structure and simplified design; There is no need to design the detailed drawing of steel grating, only the model can be indicated, and the manufacturer can design the layout drawing on behalf of the customer.

Good ventilation, lighting, heat dissipation, explosion-proof and anti-skid performance

Main uses: steel grating is suitable for alloy, building materials, power station and boiler. Shipbuilding. Petrochemical, chemical and general industrial plants, municipal construction and other industries have the advantages of ventilation, light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean and easy to install. Steel grating has been widely used in all walks of life at home and abroad. It is mainly used as industrial platform, ladder pedal, handrail, channel floor, railway bridge side road, high-altitude tower platform, drainage ditch cover, well cover, road barrier, three-dimensional parking lot, fence of government, school, factory, enterprise, sports field, garden villa, and also as external window of residential buildings, balcony fence, expressway and railway fence.
