Features: Strong flexibility, good plasticity, a wide range of uses process: selection of high-quality low-carbon raw materials, after drawing, annealing processing, soft and strong tensile resistance. The finished product is coated with anti-rust oil, not easy to rust, can be bundled according to customer requirements, each bundle is 1-50kg, can also be made into U wire, broken wire, etc., plastic inside and linen outside packaging, mainly used for binding wire, construction wire, etc.
- Hot dip galvanizing is an effective metal preservative, mainly used in various industries of metal structure facilities. The steel parts after rust removal are immersed in the molten zinc solution at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip zinc is to immerse the steel member after rust removal into the molten zinc liquid at about 600℃, so that the surface of the steel member is attached with zinc layer. The thickness of the zinc layer is not less than 65μm for the thin plate below 5mm, and not less than 86μm for the thick plate above 5mm. So as to play the purpose of corrosion prevention.

Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.
- In the cattle net generally also PVC plastic PVC plastic is coated with a layer of dark green or gray brown plastic mold on the original galvanized steel wire, to avoid the corrosion of the wire diameter, is conducive to the improvement of the wire diameter corrosion prevention and rust prevention function. So the better the raw material, the higher the price. Zinc aluminum alloy cattle mesh is the best metal mesh on the market, the price is higher than hot dip galvanized raw materials. The service life is about 80-90 years, excellent anticorrosion function.
- Heavy hexagonal net is made of low carbon steel wire galvanized large wire braid, the tensile strength of the steel wire is not less than 38kg/m2, the diameter of the steel wire can reach 2.0mm-3.2mm, the surface of the steel wire is usually protected by hot dip galvanizing, the amount of galvanizing can reach 500g/m2.

After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, 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 is easier to rust than dry environment, 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 six-sided wire mesh, prolong the service life of the product.
- The mesh size of the wire mesh specification, as well as the diameter and thickness requirements, are limited to the amount of steel and galvanized per square meter. Mainly in order to consider the corrosion resistance, prolong the service life, and in the use of the process of safety.

The main factors causing metal rust: relative humidity of the atmosphere at the same temperature, the percentage of water vapor content and water vapor saturation content in the atmosphere, known as relative humidity. Under certain relative humidity, the corrosion rate of metal antirust oil is very small, but higher than the relative humidity, the corrosion rate increases suddenly. This relative humidity is called the critical humidity. When the humidity in the atmosphere is higher than the critical humidity, the metal surface will appear water film or water droplets, if the atmosphere contains harmful impurities, dissolved in the water film, water droplets, electrolytes and aggravate corrosion.
