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. Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air. In humid air or small water containing carbon dioxide and oxygen, the surface of large rolls of galvanized wire will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer.

Heavy hexagonal mesh is made of steel wire by special machinery woven hexagonal mesh mesh. This kind of net, after cutting, assembly can be made into fence net, mountain hanging net, vegetation three-dimensional network, combination and so on.

Large hexagonal net called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compression after delivery. Then put it into the right position to open, and then put the appropriate size of the stone into the cage, the lid tight, and then the various stone cage net and adjacent stone cage net tied up.
