Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

In general, there are not many forms of dog cages, and most of them are reasonable, with trays underneath for cleaning up after your dog. I would like to remind you to make sure that the bottom plate of the dog cage with the square iron bar (that is, the bottom of the cage on the plastic tray) is not movable and can be removed and cleaned because the dog’s feces will stick to it and it will be too troublesome to remove it. There is the size of the larger wire dog cage, usually below is no wheels, this is very inconvenient, to move up will be very heavy, small size wire dog cage is not too hard to move.

There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
