Grid, also known as Steel Grid Plate, grid is a steel product with a certain distance and cross bar (twisted square steel, square steel, round steel, flat steel, etc.) , and welded into the middle with a square lattice, steel grating is mainly used to make drain cover plate, steel structure platform plate, stepladder step plate, etc. . Cross bar is generally used after twisted square steel. Can also be made of stainless steel. Steel grating with ventilation, lighting, heat dissipation, anti-slip, explosion-proof and other properties.

The utility model can be used for environmental protection noise control barriers, noise insulation and noise reduction panels for building walls, generator rooms, factory buildings and other noise sources in traffic and municipal facilities such as expressways, railways, subways, etc. , the utility model can be used for sound absorption of the ceiling and wall board of a building.
Good manufacturability; Using the process of processing before painting, the aluminum plate punching net can be processed into various complex geometric shapes such as plane, arc and spherical surface.
.
5. Production process
At present, the use of the more advanced WKC-two thousand CNC punch production equipment manufacturing. The precision of step servo motor is up to/-0.15 mm by feeding and PLC logic control, and the standard management is carried out. The plate can be pressed in the range of 10 MM0.2 mm.
Welding installation, use spot welding or two-step welding to connect the punching net, usually welding the back of the punching net, the advantage of this is that the front looks beautiful and generous, and there is no installation trace.
Stainless steel punching net heat conduction is small, heating expansion is big (austenitic whole system) , so when punching processing should choose cutting fluid with better cooling performance to lubricate. The special properties of 304 Metal Piercing Mesh are greatly affected by temperature, and the formability is greatly affected by temperature and speed. Generally high temperature, high speed, under the condition, the n value reduces, the forming part deteriorates. Therefore, using the temperature effect of the volume of warm processing methods can obtain excellent stamping performance.
The punching mesh plate can be packaged according to the user's requirements, or it can only be packaged with the consent of the customer if the quantity is small and no packaging is needed.
