What is the difference between zinc-aluminum-magnesium solar strut channel and hot-dip galvanized solar strut channel ?

What is the difference between zinc-aluminum-magnesium solar strut channel (also called zinc-aluminum-magnesium photovoltaic brackets) and hot-dip galvanized solar strut channel (also called hot-dip galvanized photovoltaic brackets)?

First of all, the zinc-aluminum-magnesium photovoltaic bracket adopts a new process, which is a different process for fire-retardant coating. In contrast, hot-dip galvanized photovoltaic brackets only coat a layer of zinc on the surface of steel products. Zinc-aluminum-magnesium photovoltaic brackets add magnesium and aluminum elements on the basis of hot-dip galvanizing. This new process makes the zinc-aluminum-magnesium photovoltaic bracket have better corrosion resistance.

Secondly, zinc, aluminum and magnesium is an alloy metal that can effectively deal with the anti-corrosion problem on the surface of steel products. In contrast, the zinc coating of hot-dip galvanized photovoltaic brackets is relatively thin, so its corrosion protection performance is relatively weak. The addition of magnesium and aluminum to the zinc-aluminum-magnesium photovoltaic bracket can greatly improve the corrosion resistance of the bracket and extend its service life.

In addition, zinc-aluminum-magnesium photovoltaic brackets also have good welding properties. Welding is a very important part of the photovoltaic bracket manufacturing process. The welding quality directly affects the stability and reliability of the bracket. In contrast, hot-dip galvanized photovoltaic brackets are prone to problems such as pores and weld corrosion during the welding process, thus reducing their welding performance.

Finally, let’s compare the cost aspects. Because the zinc-aluminum-magnesium photovoltaic bracket adopts a new process, its cost is lower than that of hot-dip galvanized photovoltaic bracket. According to market conditions, the cost of zinc-aluminum-magnesium photovoltaic brackets is reduced to about RMB1,000 yuan per ton, which is more cost-effective than hot-dip galvanized photovoltaic brackets.

In short, compared with hot-dip galvanized photovoltaic brackets, zinc-aluminum-magnesium photovoltaic brackets have superior advantages in terms of corrosion resistance, welding performance and cost. Therefore, if you are considering the purchase of photovoltaic brackets, we strongly recommend that you choose zinc-aluminum-magnesium photovoltaic brackets, which will bring longer-term stability and reliability to your photovoltaic system.
