What Are The Advantages Of Zinc-aluminum-magnesium Square Tubes in The Application Of Household Photovoltaic Sunshine Rooms And What Are The Common Specifications？

On the basis of galvanizing, Al, Mg, Ni, Cr, and other alloying elements are added, and the zinc-aluminum-magnesium coating is composed of primary zinc phase, zinc/zinc-magnesium binary eutectic phase, and zinc-aluminum-magnesium ternary eutectic phase so that The surface of the steel plate forms a dense barrier that effectively prevents the penetration of corrosion factors, which greatly improves the corrosion resistance of the material performance. The advantages of zinc-aluminum-magnesium alloy materials in photovoltaic supports are more obvious.

Compared with the traditional hot-dip galvanized square tube, the zinc-aluminum-magnesium square tube has greatly improved corrosion resistance and self-repair performance, helping to prolong the service life of the bracket. The advantages of the zinc-aluminum-magnesium square tube for photovoltaic brackets are very significant. The zinc-aluminum-magnesium coating of the zinc-aluminum-magnesium square tube is a ternary alloy coating whose main component is zinc, and the content of aluminum and magnesium is between 1.5% and 8% (the magnesium content is not less than 0.2%).

The advantages of zinc aluminum magnesium square tube in the application of household photovoltaic sunroom：

1. Cost reduction. Zinc-aluminum-magnesium materials are pretreated by continuous galvanizing on the basis of hot rolling. After the zinc-aluminum-magnesium coating plate is processed and formed, it is directly provided for engineering use, shortening the processing period of component products, and the project construction period is well controllable. And reduce the management and labor costs required for the post-heat soaking treatment process.

2. Reduce pollution and benefit environmental protection. Canceling the production process of hot-dip galvanizing can reduce serious environmental pollution problems and play a positive role in environmental protection; and zinc-aluminum-magnesium coating environmental protection monitoring REACH monitoring, ROHS monitoring, and food contact materials The monitoring is in compliance with the limit requirements, and zinc, aluminum, and magnesium products are more in line with the national requirements for green environmental protection.

3. Zinc-aluminum-magnesium has the self-healing ability of the cut section of the coating. During the use of the zinc-aluminum-magnesium material, the coating near the cut or scratch position gradually forms a dense layer composed of zinc hydroxide, alkaline zinc chloride, and magnesium hydroxide. The protective film (that is, white rust) has good adhesion, high density, and low conductivity, and can effectively separate the external corrosive medium from the bare metal substrate, thereby preventing further corrosion of the exposed cut and inhibiting the corrosion of the cut and scratched position Effect. At present, the incision and surface neutral salt spray test of zinc, aluminum, and magnesium materials have reached 4440 hours without red rust.

4. The zinc-aluminum-magnesium material has stable performance, and the size of the material is easy to control, which is convenient for the standardization and mass production of photovoltaic brackets. Zinc-aluminum-magnesium materials have been used in the photovoltaic industry with good surface quality, super corrosion resistance, stable performance, good environmental performance, and low-cost advantages and have been recognized by many power companies, and have also brought good economic benefits to society benefits.
