Customers often ask whether to choose hot-dip galvanized or galvanized magnesium-aluminum materials for solar mounting systems. the galvanized magnesium-aluminum material does have a certain self-repair function after processing, but there may still be a little spot.

The thickness of the steel in the hot-dip galvanized material and the galvanized aluminum-magnesium material is the same, but the thickness of the coating is different. The hot-dip galvanized coating is about 85um (thickness can be selected), and the galvanized aluminum-magnesium coating is about 20um (currently only this thickness).

Our company has been researching galvanized magnesium-aluminum materials. About five or six years ago, the market began to recommend galvanized magnesium-aluminum solar brackets. At present, the first batch of galvanized magnesium-aluminum photovoltaic brackets is only five or six years old. The product life of zinc and magnesium aluminum is also uncertain. So to be on the safe side, we recommend using hot-dip galvanized materials. And in the past two years, there have been very few recommendations for galvanized magnesium-aluminum photovoltaic brackets on the market.
