The materials of solar ground brackets mainly include aluminum alloy, stainless steel, carbon steel, hot-dip galvanized, galvanized aluminum magnesium, weather resistant steel, etc.
Material Classification
Aluminum alloy: lightweight, corrosion-resistant, but with low load-bearing capacity, mostly used for roofs of civil buildings.
Stainless steel: Excellent anti-corrosion performance, surface treated with anodizing or anti-corrosion treatment, with a service life of up to 20 years.
Carbon steel: surface treated with hot-dip galvanizing, can be used outdoors for 30 years without rusting, has high bearing capacity, and is widely used in ground power stations.
Hot dip galvanizing: a traditional anti-corrosion process suitable for windy areas, with a thickness of up to 2.5mm
Galvanized aluminum magnesium: alloy sheet, resistant to chlor alkali corrosion, suitable for harsh environments such as deserts and saline alkali land.
Weathering steel: With excellent mechanical properties and corrosion resistance 2-8 times that of carbon steel, it has a rust colored appearance and is maintenance free.
Material Selection
In windy areas, carbon steel brackets (thickness ≥ 2mm) or galvanized aluminum magnesium brackets are recommended.
