roller mesh screen

Although to be able to reduce the cost of production, but the overall strength of the product will have a great lack, so in this case will also let it have a great strength drop. Of course, in the mall, the higher the intensity of the data in the production of the higher the implementation of norms, naturally there will be certain progress in the price.

On the highway, the barbed wire protective net is generally used to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of highway land and other issues of traffic safety facilities. There are many forms of barbed wire protective nets, commonly used are metal, woven nets, barbed wire and evergreen green gracilaria. In the densely populated areas set up metal woven net, people and animals are less sparse areas of the form of barbed wire, in the toll station, service area and other sections of the structure of hedge and barbed wire. In the past two years, considering the aesthetic problem, some highways in the Pearl River Delta region adopted the fruit plastic spot welding mesh (usually said guardrail mesh), the barbed wire protective mesh is more beautiful, but also durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beauty of the section available.

Now the production of stainless steel blade barbed rope unless it is a specially customized model, under normal circumstances are the use of a knife length of 22mm mold production, that is, we usually say bto-22 type. It’s not necessarily the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the required length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.

If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

The size of the galvanized layer of galvanized iron wire is related to the anti-corrosion ability and application effect of galvanized wire. The thickness of the galvanized layer of the general standard galvanized wire products should be tested after the product is formed. There are three specific test methods. Weighing method and cross section microscopy method are destructive experimental methods, and magnetic method is a relatively rigorous non-destructive method, but the measurement steps and requirements are relatively high, so they are rarely used in specific applications. The first two methods are intuitive and common methods.

Wire factory reminds you in the purchase of galvanized wire, should be stored in dry, ventilated conditions, do not contain corrosive gases, do not mix with organic volatile gas produced paint, plastic and other substances in a good environment. If possible, we can add reliable inner packaging for galvanized parts, and put desiccant. If the zinc layer of white spots and long hair, can only be removed by mechanical methods, and then normal passivation, or completely washed off the zinc layer after re-plating.

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. Pet cage is mainly used for family pet breeding and protection. Our Tianfu metal products company specializes in the production of various specifications of pet cages such as pigeon cage, dog cage, bird cage, parrot cage and so on.

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, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.

When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.

In the use of time do not need to carry out daily maintenance and maintenance, not only can save a lot of time, but also can reduce the cost, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different kinds, can be selected according to their own needs, has good flexibility and elasticity. The main role of annealing wire is to control its degree of hardness and softness. When making annealing wire, it is made of steel wire.

That said, it can always deform by pulling hard without changing its integrity, so cold drawing has usually reached a limit, which is not a problem, because without this property it increases hardness, which is the desired effect. Cold wire drawing encountered more rain, when the climate is wet, easy oxidation and rust. Therefore, in the storage process should pay attention to avoid rust.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
