Zinc-aluminum-magnesium solar bracket

Concise Overview

Photovoltaic solar brackets are mostly processed from black parts, and then sent to hot-dip galvanizing plants for galvanizing or directly bent and formed using hot-dip galvanized steel strips. However, with the advancement of technology, the current trend is to directly use zinc-aluminum-magnesium strip steel for bending and forming. Compared with hot-dip galvanized sheets, zinc-aluminum-magnesium has obvious advantages in cost, corrosion resistance and sheet strength.

Product Insights

Zinc-aluminum-magnesium solar bracket

The zinc-aluminum-magnesium bracket is innovated on the basis of traditional hot-dip galvanizing coating. A special alloy coating is generated by adding appropriate Al, Mg and other trace alloy elements into the plating solution.

The advantages of zinc aluminum magnesium solar bracket are:

1. Easy to stamp
Solar photovoltaic brackets need to withstand external wind loads and snow loads. Since the friction coefficient of the zinc-aluminum-magnesium strip steel is 15% lower than that of pure zinc coating, it can remain stable during the reciprocating friction process, ensuring the stability and safety of solar photovoltaic components.

2. High corrosion resistance
Solar photovoltaic brackets are exposed to harsh outdoor environments for a long time and are easily corroded by the atmosphere and water.
Zinc-aluminum-magnesium strip steel undergoes reasonable alloy design and heat treatment process. When the cut part is exposed, the magnesium (Mg) component in the coating is conducive to promoting the formation of a very stable and dense protective film, which can form a dense oxide layer and barrier layer, thereby effectively preventing corrosion.

3. Good durability
Solar photovoltaic brackets need to withstand the influence of external environmental factors such as solar radiation, temperature differences and wind and rain erosion for a long time. Zinc-aluminum-magnesium strip steel undergoes strict surface treatment and coating process, which can effectively resist these influences and extend the service life of solar photovoltaic brackets.

In addition, zinc-aluminum-magnesium strip steel also has good plasticity and welding performance, which can meet the shape requirements and installation requirements of solar photovoltaic brackets. At the same time, it also has low density and good recyclability, which reduces the weight and environmental pollution of solar photovoltaic brackets and meets the requirements of sustainable development.

The biggest advantage of zinc-aluminum-magnesium bracket is their high corrosion resistance, especially cut corrosion resistance.
