ZAM vs Galvanized?
1. Definition and principle
Zinc-aluminum-magnesium and hot-dip galvanizing are both anti-corrosion treatment methods. Hot-dip galvanizing refers to immersing steel in molten zinc liquid to form a layer of zinc-iron alloy on the surface; while ZAM steel material combines zinc, magnesium, and aluminum The elements are mixed according to a certain proportion and coated by high-temperature heat treatment to form an alloy layer with excellent performance to achieve the purpose of anti-corrosion.
2. Anticorrosion comparison
Hot-dip galvanizing is a traditional anti-corrosion method with strong anti-corrosion performance, but the anti-corrosion performance of zinc, aluminum, and magnesium is even better, especially in some areas where the climate is humid and the air pollution is serious, the corrosion resistance of ZAM steel material is even better.
3. Comparison of surface treatment
Hot-dip galvanizing has good surface treatment performance, and the surface after treatment is smooth and uniform, while the surface treatment of zinc, aluminum, and magnesium is relatively poor, but it can be improved by subsequent sandblasting, spraying, and other methods.
4. Comparison of service life
Due to the better anti-corrosion properties of zinc, aluminum, and magnesium, the service life of zinc, aluminum, and magnesium is longer under the same use environment, but the use cost of zinc, aluminum, and magnesium is relatively high.
5. Environmental protection comparison
In the hot-dip galvanizing process, due to the high content of zinc used, a large amount of waste residue and waste water will be produced, causing certain pollution to the environment; while zinc, aluminum, and magnesium do not contain harmful heavy metals, the waste is also reduced during the heat treatment process. produced, so it is relatively environmentally friendly.
Yuantai Derun is the famous brand name for steel hollow sections in China, started to produce ZAM tubes and coils in 2023, April officially.
We know you have been importing ZAM coils and tubes for
