Photovoltaic Solar Mounting Bracket Hollow Section for Sun Room

Short Description:

With the introduction of PV power stations into thousands of households, PV power stations and roofs of residents will be integrated to provide photovoltaic solar room solutions which are suitable for local residential buildings according to local conditions. It not only makes smart use of idle space, but also has comfortable, beautiful and high safety performance. According to the specific situation of each family, the design scheme of “sun room” can not only eliminate the roof seepage and water leakage, but also absorb part of the sun heat, reduce the indoor temperature, improve the living environment, so that users have an exclusive “sun room”.

In order to ensure the safety, stability and reliability of the "sun room", the whole support structure of the solution adopts the light and high strength magnesium aluminum zinc steel welded and formed hollow section. Through strict calculation and testing, fully considering the bearing, wind resistance, earthquake resistance and other factors. Compared with the traditional products, the magnesium aluminum zinc bracket has better corrosion resistance and a certain automatic repair ability with better protection ability for the cutting edge.

Advantages of Zinc-Al-Mg Solar Mounting Bracket

As solar power grows in popularity as an alternative energy source, the importance of durable and efficient mounting brackets cannot be overemphasized. Material selection is critical to ensuring a durable and successful installation. Zinc-aluminum-magnesium steel is the best choice for solar mounting brackets because it offers a unique combination of strength, corrosion resistance, and stability.

1. High strength to weight ratio
Zinc-aluminum-magnesium alloys have a higher strength-to-weight ratio than other traditional stent materials such as steel and aluminum. This means the material is lightweight but strong enough to hold the solar panels securely in place, reducing shipping costs and making installation quicker and easier.

2. Corrosion resistance
Zinc-aluminum-magnesium steel has superior corrosion resistance, making it ideal for outdoor and harsh environments. The material's corrosion resistance extends the life of the bracket and improves the overall durability of the solar panel system. Additionally, zinc-aluminum-magnesium alloys are highly resistant to sea salt and other environmental pollutants, making them ideal for installing solar panels in coastal areas.

3. Minimal maintenance
Once installed, Zn-Al-Mg solar mounting brackets require minimal maintenance, reducing overall maintenance costs and man-hours. This material eliminates problems such as rust, corrosion, and peeling paint, and requires less maintenance than other traditional bracket materials.

4. Environmental friendly
The natural composition of the zinc-aluminum-magnesium alloy makes it environmentally friendly. The material is 100% recyclable and has a low carbon footprint, making it a sustainable choice for solar panel systems. This aligns with solar energy's goal of reducing dependence on fossil fuels and minimizing damage to the environment.
