architectural expanded metal mesh

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

There are many categories of large coils of galvanized wire, and different categories can be applied to different scenarios. Galvanized iron wire common application is the application of the construction industry, one is the use of binding wire, whether it is the binding of scaffolding or reinforcement, need galvanized iron wire to carry out, the common specifications are 22 and 24 wire, common length of 30cm, 35cm, 40cm, 45cm, 50cm. There is also 20kg or 50kg a bundle of 18, 16, 14, 12, 10 galvanized coil wire.

The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
