Mesh Specification
The manufacture of mesh is started with producing wire. The wire production includes: forging, rolling, annealing and drawing. The wire with right material and wire diameter will be produced. Then the warp wires will be put and prepared on the weaving machine, and then start weaving. From wire to mesh, manufacture process is operated with high standard quality control system. There will be quality test for each batch of product, such as test to diameter tolerance, content, mesh aperture, etc.
Packing Process & Transportation
Packaging: Seal up, with plastic inside and wooden case or carton outside; or according to the customer's requirements.
Transportation: By air or By sea
