- 1. The content of alloying elements.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
- Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.
- Determine the size of the dog cage based on the dog’s actual adult size. In general, the cage should be three times the size of the dog’s body and give him enough room to turn around and so on.
Post time: 01-06-23- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
- 3. The front and back twist barbed wire has a beautiful appearance
- Non-proportional extension strength: It is mainly for hard steel without yield point. It is defined as the stress where the residual elongation of the standard distance part reaches 0.2% of the length of the original standard distance.
Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
Post time: 13-12-223. Zinc layer structure: The structure of zinc layer includes grain size, grain shape and the combination of zinc layer and substrate, etc., which has a certain impact on corrosion resistance. In general, the finer the grain size, the denser the structure, and the better the corrosion resistance.
Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After knowing these, we can effectively prevent the corrosion of the dip plastic six side wire mesh, prolong the service life of the product.
- Cold galvanizing, also called galvanizing, is the steel wire placed in the plating tank, through the one-way current to make the metal surface slow galvanized, zinc is slow, and the thickness is only one tenth of hot dip galvanizing, zinc layer is thin, so the rust resistance is not good, placed in the outdoor usually a few months will rust, applied in the outdoor generally in the plastic coating.
Because the coastline is generally erected for protection, but often because of environmental factors lead to serious corrosion of the barbed rope lost its function. Stainless steel barbed rope is specially set up to prevent corrosion. Stainless steel barbed rope because the environmental requirements are not very high can be very good protection itself will not have a problem to extend the use of life, so that you can ensure safety.

Post time: 14-06-24- Steel mesh factory – improve the construction speed. Using electric welding to connect steel mesh can accelerate the construction speed. As long as electric welding connecting steel mesh is laid as required, concrete can be poured, eliminating on-site cutting, pouring, binding and other links. Can save 50-70 percent of the working time, greatly accelerate the construction progress, shorten the construction period.
Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.
All steel wire components Master High galvanized chain link tennis court system for hot dip galvanizing and protection to ensure coating. The link used to attach the chain link structure between the frame terminals of the post is made of aluminum, resulting in maintenance-free security. Some units used in the tennis court system are made of pressed steel and cast iron for increased durability. The role of steel wire mesh in the external wall plastering is mainly a measure to prevent falling off from the point of safety. The role of anti-cracking is relatively small, because of the location of the problem;
- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
