The production of large rolls of galvanized wire iron can be divided into two categories, is directly from the iron ore after iron stroke exercise out of the metal, the composition of the ore is iron oxide, silica and other miscellaneous stone.

The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

Heavy hexagonal net, also known as large size hexagonal net, or gabion mesh, made of steel wire by twisting mesh machine. This product is very versatile. Can be used for slope support, foundation pit support, mountain rock surface hanging net shotcrete, slope planting (greening), railway highway isolation barrier, it can also be made of stone cage, stone pad, for rivers, DAMS and seawall anti-erosion protection and reservoirs, river interception with stone cage.
