  • We must have a certain understanding of the hexagonal net, we are swayed by the beautiful shape of the hexagonal net, not only the shape of the hexagonal net is very beautiful, in fact, the practical value of survival is very high. The introduction of the relevant information should be very clear to know the high-speed road guardrail network, hexagonal mesh of all kinds of guardrail network, the value of the high-speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides to take care of, but also to reach a very close utility.

  • 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:

  • In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
