Is the scaffolding galvanized or sprayed with zinc? At present, the scaffolding is mostly galvanized, which is anti-corrosion and has a longer service life. The following is a detailed introduction to the difference between galvanized and sprayed zinc:
Hot-dip galvanizing is also called hot-dip galvanizing, hot-dip galvanizing, which belongs to rack plating. It is not only plated with thicker pure zinc on steel after a very complex physical and chemical action when zinc is in a liquid state. layer, and a zinc-iron alloy layer is also formed. This kind of plating method not only has the corrosion resistance characteristics of electro-galvanizing, but also has a zinc-iron alloy layer. It also has strong corrosion resistance unmatched by electro-galvanizing. Therefore, this plating method is especially suitable for strong corrosive environments such as various strong acids and alkali mists.
Hot-dip galvanizing is an effective method of metal anti-corrosion, which is mainly used in metal structural facilities in various industries. It is a method of immersing steel components in molten zinc to obtain a metal coating. The process is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ℃, so that the surface of the steel parts is attached with a zinc layer, so as to achieve the purpose of anti-corrosion.
Zinc spraying is also called blowing plating: the thickness of the coating does not exceed 10um, the anti-corrosion life is not as long as that of hot-dip galvanizing, the appearance is even and smoother than that of hot-dip galvanizing, there is no zinc slag, burrs, and the cost of galvanizing is also low. Thermal spray zinc is especially suitable for large and large workpieces, thin parts, boxes, and tanks that cannot be completed by hot-dip plating, eliminating the trouble of hot-dip galvanizing, cutting, and re-welding.
The material of the World Scaffolding is galvanized strip pipe, which is welded, and the process is carbon dioxide gas shielded welding.
