Relevant Knowledge about Zinc-aluminum-magnesium Tubes in Zinc-aluminum-magnesium Photovoltaic Brackets

Zinc-aluminum-magnesium pipe is a square tube shape rolled from zinc-aluminum-magnesium strip steel through process treatment. 

Compared with traditional hot-dip galvanized square and rectangular tubes, zinc-aluminum-magnesium tubes have greatly improved corrosion resistance and self-healing performance. The advantages of zinc-aluminum-magnesium square and rectangular tubes when used in photovoltaic brackets are very significant. The zinc-aluminum-magnesium coating of zinc-aluminum-magnesium pipe is a alloy coating whose main component is zinc, and the content of aluminum and magnesium is between 1.5 and 8% (of which the magnesium content is not less than 0.2%).

1. The aluminum element in the zinc-aluminum-magnesium photovoltaic bracket will form a protective film - aluminum oxide after daily contact with the air. This protective film can prevent the bracket from being corroded by the air.

2. Photovoltaic brackets are generally suitable for outdoor use and go through a low-temperature stage every year. Photovoltaic brackets made of zinc, aluminum and magnesium have good low-temperature resistance.

3. The conductivity of the zinc-aluminum-magnesium photovoltaic bracket is better than that of some other materials, so when a weak current is generated on the photovoltaic bracket, it can be conducted well.

4. This material is not only good for use, but also good for manufacturers. It is easy to process and can be used for any operation. The cut surface does not need to be coated with anti-corrosion coating, and it can be restored by itself. In this way, manufacturers When the cost is low, the sales price will naturally be lower.

5. The environments for installing photovoltaic brackets are different, and the requirements for the overall structure of the photovoltaic bracket are also different. Photovoltaic brackets of various structures can be produced using zinc, aluminum and magnesium materials, which is what everyone calls easy to form.

Galvanized aluminum-magnesium is an alloy coating in coated steel products. The mass fraction of metal elements in the coating is: 53% aluminum, 43% zinc, 2% magnesium, 1.5% silicon and other elements.

Zinc-aluminum-magnesium has the ability to self-repair the cut section of the coating. During use, the coating near the cut or scratched position of the zinc-aluminum-magnesium material gradually forms a dense protective film composed of zinc hydroxide, alkaline zinc chloride and magnesium hydroxide. (That is, white rust) has good adhesion, high density, and low conductivity. It can effectively separate the external corrosive medium from the exposed metal matrix, thereby preventing further corrosion of the exposed cuts and inhibiting the corrosion of cuts and scratches.
