rubber threshold strip for front door

Its wire diameter specifications include: 8#-24#, with thick coating, corrosion resistance, strong coating and so on. And according to the special needs of users, according to industry standards to provide various specifications of galvanized wire. Low carbon steel wire is called galvanized iron wire after drawing and galvanized, so galvanized wire products have certain characteristics. In order to better let galvanized wire play an effect, in the process of galvanized wire, generally according to customer needs to control the thickness of galvanized wire zinc layer, so that galvanized wire can meet the needs of customers.

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.

Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.

After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.

Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.

1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

Iron and steel in the condition of cooling on the surface galvanized, and hot dip galvanized steel pipe in the condition of hot dip on the surface, its adhesion is strong, not easy to fall off, hot dip galvanized pipe although also rust phenomenon, but in a long period can meet the technical and sanitary requirements.
