Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

In addition, the corrosion resistance of hot-dip galvanized wire will also be affected by other factors. For example, in different environments, especially in some special chemical environments, such as acidic or alkaline environments, the corrosion resistance of hot-dip galvanized wire may be affected to a certain extent. At this time, it may be necessary to use other materials that are more resistant to corrosion to replace the hot-dip galvanized wire.

We often choose what kind of barbed rope instead of the type of barbed rope. In fact, the type of barbed rope is as important as the type of barbed rope. Let’s talk about the difference between 304 and 201 of the barbed wire rolling cage.

Annealing wire is widely used because it has a good elasticity and flexibility, in the annealing process can be good control of its hardness, it is mainly made of iron wire, more often used in the construction industry binding wire use. In the production of the wire factory, annealing wire will be processed according to the properties of the material, according to the needs of different to change its hardness degree, can make it has more advantages, can reduce the consumption of metal, reduce the cost of production.

Galvanized hook net cost is low: galvanized process is faster than other coating construction method, and can avoid the installation of time required on the site brushing; Galvanized hook net features: not easy to corrosion, long life, strong practicality, uniform mesh, smooth net surface, simple weaving, beautiful and generous, high quality mesh, wide mesh, thick wire diameter. Can do breeding protection net, coal mine protection net, court protection net, stadium fence net, training field protection net, slope protection, green enclosure, river, building, residential district safety protection, workshop/warehouse isolation, etc..

The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.

Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.

Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
