Aluminum alloy grating plate, also known as steel grating, steel grating plate or grating plate, is welded from flat steel and twisted steel. The grating is mainly used in rest platforms, walkways, ditch covers, and step boards. It is also used in environmental protection equipment and sewage treatment, and is increasingly being widely adopted due to its superiority.

The width of the gap between the grid bars can be set according to the method of removing dirt and the requirements of the water pump. The manual clearance of the grid gap is generally 16-25mm. The grid in front of the sedimentation tank or settling tank is generally 15-30mm, with a maximum of 40mm. There are three commonly used mechanical slag cleaning equipment, namely chain type, mobile type, and wire rope traction type grid cleaning machines.

According to the size of the spacing between the grid bars, the grid is divided into three categories: coarse grid, medium grid, and fine grid. There are three types of slag removal methods for grilles: manual grilles, mechanical grilles, and hydraulic cleaning grilles. According to the different structural characteristics of the grille, it can be divided into various forms such as rake type, circular type, arc type, rotary type, drum type, rotary type, toothed rake type, and stepped type.

Grille equipment is generally used on the inlet channel of sewage treatment or at the inlet of the collection tank of the lifting pump station. Its main function is to remove larger suspended or floating objects in the sewage, to reduce the treatment load of subsequent water treatment processes, and to protect water pumps, pipelines, instruments, etc. When the intercepted slag amount is greater than 0.2m3/d, mechanical slag cleaning is generally used; When the slag amount is less than 0.2m3/d, manual slag cleaning or mechanical slag cleaning can be used.

The application of grilles has a wide range of uses in construction, design and decoration, sewage treatment, engineering applications, and other fields.
