In recent years, with the emphasis on dust suppression in China, the application of dust suppression networks has increased. Basically, the wind and dust suppression nets are mainly made of high quality GL galvanized steel coils. It has also been mentioned that rust prevention of galvanized sheets is also mentioned. Better performance and the need for galvanized sheets for wind and dust screens. So which of these two materials is better?
The difference between the two is the difference in surface
The difference between hot sale galvanized steel coil and high quality GL Galvanized Steel Coil 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 substrate, that is, the zinc material replaces the substrate to corrode and rust. The metal is protected and the internal substrate is damaged only when the zinc is completely corroded.
The surface of the aluminum zinc steel coil in stock is about 55% aluminum, 43.5% zinc and a small number of other elements. Under the watch, the surface of the galvanized layer is a honeycomb structure, and the "honeycomb" made of aluminum is wrapped with zinc. In this case, although the aluminum-zinc plating also functions as anode protection, on the one hand, since the zinc content is reduced, on the one hand, the zinc material is wrapped with aluminum, and electrolysis is not easily generated. Therefore, the effect of the anode protection is greatly reduced, so once the galvanized sheet is cut and substantially loses protection at the cutting edge. In this case, it will rust quickly, so the galvanized sheet should be cut as little as possible.
Galvanized Steel Coil made in China is the metal materials we often use. Galvanized sheets for wind and dust screens are hot dip galvanized sheets. The hot dip galvanizing treatment will cover the surface layer of the steel sheet having a thin zinc layer. Effectively prevents air and moisture from entering and prevents an internal substrate from rusting.
In cities where the air is humid and the rain is abundant, once a certain point of the galvanized sheet is rusted, if the measures are not taken in time, the rust will become larger and larger until the entire surface; and the high-quality GL galvanized steel coil will rust evenly and will not cause diffusion.
After comparing the two, it can be seen that the Galvanized Steel Coil made in China is superior in terms of service life and corrosion resistance, and the price of the galvanized sheet is also lower than that of the galvanized sheet. Therefore, it is recommended that you choose windproof and dustproof. The material of the mesh should be galvanized as much as possible.
