Concrete brackets are mainly used in large-scale photovoltaic power stations. They are only suitable for outdoor installation in areas with sound foundations due to their heavy weight, but offer high stability and can support large-sized solar panels.
Aluminum alloy brackets are generally applied in solar energy systems on the roofs of civil buildings. Aluminum alloy features corrosion resistance, light weight, aesthetic appeal and durability, but has low load-bearing capacity that prevents its use in photovoltaic power station projects. Additionally, aluminum alloy is slightly more expensive than hot-dip galvanized steel.
Steel brackets boast stable performance, mature manufacturing processes, high load-bearing capacity and easy installation, making them widely used in civil, industrial solar photovoltaic systems and solar power stations. Among them, section steels are factory-produced with uniform specifications, stable performance, excellent corrosion resistance and attractive appearance. Notably, the assembled steel bracket system allows on-site installation by assembling channel steels using specially designed connectors only. It enables fast construction without welding, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this product lies in its complex connector technology and various types, which impose high requirements on manufacturing and design, resulting in a relatively high price.
