PVC coated barbed rope is widely used for railway highway protection, but also for safety protection of rivers, embankments and seawalls, so as to better protect the safety of people and animals.

6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

Some customers are more concerned about the quality of the problem, so for the service life is more important, thorn rope factory will generally recommend the use of high zinc thorn rope or stainless steel thorn rope.

Benefits of using a pet cage:

Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor.

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

Immersed six edge barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, specifically, is prone to fracture, lose the original protection function. 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 understanding these, we can effectively prevent the corrosion of the six sides of the wire, prolong the service life of the product.

Wire mesh first welding after galvanized is through the end of welding and then cold this company to produce wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
