Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the low thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
No matter how old dogs are, they seem to love to touch noses with people and other animals. In fact, dogs touch noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t nuzzle every human or every animal. They pick and choose who to nuzzle. If they don’t like you, or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell the puppy’s body.
Traditional barbed wire is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the limitations of the use of traditional barbed wire gradually exposed, such as: aquaculture, to the chicken circle cage can not be too dense, the wire can not be too thick, woven mesh wire once the mesh will become soft. We also have coping methods: 1, cotton gouging, rolling straight wire into wavy shape, but still not enough to raise chickens with mesh can only be extended to the beak can not feed! 2, is the electric welding net, with the current of the longitude and weft wire spot welding together, the mesh is not limited to do more.
Hot dip galvanized wire is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, and the matrix metal forms the infiltration layer, the corrosion resistance is good, the outdoor environment of hot dip galvanized wire can be maintained for decades.

The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
In our daily life, what we can bend with our hands is basically galvanized iron wire, not steel wire. It has a high zinc content, which ensures excellent toughness and resilience, as well as ultra-high corrosion resistance, which can be maintained in outdoor environments for decades. There are many practical galvanized iron wire, such as strong reliability, galvanized layer and iron together, forming a special metallurgical structure, in the use and transportation process, can ensure that it will not be mechanical damage.
6, the use of special formula and special UV absorbent, no fading, no yellowing, no peeling, no cracking, no foaming, no moth, the use cycle can be more than 30 years.
Hot – plated wire average performance: reflected in its cross – section, longitudinal uniformity. In the actual process of operation, such as steel wire jitter, the surface scum plating pot and other reasons will cause the surface of galvanized wire galvanized layer accumulation, should strive to solve the problem. In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of the galvanized layer.
Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.
