Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.

2, mesh, mesh also directly affect the price of stone cage net
- We have to carefully choose a good cage for the parrot, so that it has a comfortable home.
- Both sides of the galvanized welding net exposed can not be more than 2mm, so as to be qualified. And in the welding mesh of each warp and weft wire cross place, must be welded very firm, and if you want to welding very firm, both sides must have some warp and weft wire out, and the length must be controlled within two millimeters. From the mesh distribution is not uniform, galvanized is not uniform, but also to see whether the welding mesh is qualified standards.

The guide frame of spray hook net wholesale is composed of guide beam and park core pile, their interval distance is about 3 meters, the spacing of guide beam should be about 1 cm higher than the wall. When installing the guide beam, its position should be far away from the net, and the surround-pile should not be expanded, which will make the surround-pile sink or change its shape.

The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.

The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).

With the improvement of living standards and the reduction of family size, keeping pets is becoming a way of life for many people. According to statistics, the number of pet dogs has reached more than 100 million, and the trend is increasing rapidly every year. Beijing alone had more than 900,000 licensed dogs in 2010, according to a survey, and the number of pet cats is also very large.

Due to the influence of production process or other factors, the zinc layer of galvanized wire products will be different to a certain extent, especially ordinary galvanized can not reach the beauty of electric galvanized, ordinary galvanized wire zinc layer is mainly for anticorrosion and corrosion prevention. Large volume galvanized wire products refers to the use of high quality low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes, some galvanized wire products are made of iron wire galvanized.

Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.

The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
- 3, barbed rope protection net in the bridge, channel, should be toward the bridge head cone slope (or end wall) direction surrounded, should not leave for people, livestock can drill into the gap.

In order to make the zinc content of steel wire stable in the future, and maintain its uniformity, as far as possible to reduce the zinc content, and effectively reduce zinc consumption to the actual work, the following measures are proposed by the wire factory:
- Through the maintenance of galvanized wire, it can not only greatly prolong its service life, but also improve its efficiency in the daily use process. Because the labeled electrode potential of zinc is -0.762v, which is negative than iron, zinc becomes the anode when the galvanic cell is formed after being corroded by the medium. It itself is dissolved to protect the steel matrix. The duration of the protection of galvanized wire layer has a great relationship with the thickness.
