High strength weatherproof composite Support

The composite support is made by pultrusion process, corrosion-resist resin be as matrix and basalt fiberglass be as reinforcement,  It has high strength, high modulus, and lightweight etc advantages.

Major characteristics:

1) Lightweight, high strength, and good flexibility.

The specific weight of composite supports is about 1/4 of steel, and the bending strength is more than 6 times of aluminum alloy. It can withstand wind and snow loads under extreme conditions, and the biggest difference from metal materials is that the structure almost undergoes invisible changes after the load is removed, providing strong guarantees for the safety of photovoltaic power generation and its application in harsh environments.

2) High and low temperature resistance

Composite materials can withstand extreme temperatures (-70 ℃ to 100 ℃), and within this temperature range, the mechanical properties of the material are almost unaffected by temperature. And its structure is dense, which can be used for a long time in high humidity environments.

3) Corrosion resistance

Composite supports have strong corrosion resistance and can withstand various degrees of corrosion from gas and liquid, such as acids, alkalis, salts, and organic solvents. Unlike traditional steel, this material does not corrode or rust, not only maintaining a clean appearance but also greatly reducing maintenance costs. When used in the field of photovoltaic industry, it can effectively demonstrate its corrosion resistance characteristics.

4) Weathering resistance

In high and low temperature environments such as high temperature, high humidity, UV exposure, rain and snow, it’s mechanical properties and structure do not undergo significant changes. Composite materials can resist UV radiation, and after 1000 hours of UV irradiation, the strength retention rate can reach over 95%.

5) Designability

Composite materials have the characteristic of strong designability, and different structures can be designed according to the stress characteristics. Different matrix and reinforcement materials can also be selected according to the different structural properties to meet different requirements.
