What kind of galvanized sheet should be used in the production of windscreen punching nets?

In recent years, with our attention to environmental protection, more and more applications of windproof and dust suppression nets made of punched nets have been made. Most of the windproof and dust suppression punching nets use galvanized sheet as the basic steel, but it is also said that the galvanized sheet has better rust prevention performance, and it is required that the processed substrate of the product uses a galvanized sheet. So which of these two materials is better? What is the difference between the two?

  The difference between the two is the difference in appearance

  1. The difference between galvanized sheet and aluminized zinc sheet is mainly due to the difference in the coating. The surface of the galvanized sheet is evenly distributed with a layer of zinc material, which has an anodic protection effect on the base material, which means that the zinc material replaces the base material. Rust protects the base metal. Only when all zinc is corroded can the base metal inside be damaged.

  2. The coating on the surface of the aluminized zinc plate is about 55% aluminum, 43.5% of zinc and a small amount of other elements. The surface of the aluminized zinc layer is a honeycomb structure, and the "honeycomb" composed of aluminum is wrapped with zinc. In this case, although the aluminized zinc layer also plays the role of anodic protection, on the one hand, due to the reduction of zinc content, on the other hand, the zinc material is wrapped with aluminum, and it is not easy to produce electrolysis, so the effect of anodic protection is greatly reduced. The zinc plate is cut, and the protection is basically lost at the cut edge. In this case, it will rust quickly, so the aluminum-zinc plate should be cut as little as possible. The galvanized coil is a very common metal material. The galvanized steel used in the product is a hot-dip galvanized sheet. The hot-dip galvanizing treatment will cover the surface of the steel sheet with a thin layer of zinc. This layer of zinc can be effective. Prevent the entry of air and moisture, and prevent the base material inside from rusting.

  3. In cities where the air is humid and there is a lot of rain, once corrosion occurs at a certain point of the aluminized zinc plate, if the measures are not taken in time, the rusted area will become larger and larger until the entire surface of the plate; It is rust at a certain point and does not cause diffusion.

  After comparing the two, we can also see that in terms of service life and corrosion resistance, galvanized sheet is better, and the price of galvanized sheet is cheaper than aluminized zinc sheet, so we recommend our customers to When purchasing perforated windshield walls, it is best to use galvanized materials, which can save costs and be durable.
