The durability of ground solar brackets is affected by multiple factors. Based on existing information, their service life is usually between 20-30 years, as shown below:

Main influencing factors

Material quality：
Carbon steel with special surface treatment (such as galvanizing), high-quality aluminum alloy, stainless steel or carbon steel brackets generally have a lifespan of over 20 years, up to 30 years
Poor quality materials are prone to rust and corrosion, significantly reducing their service life.

Surface treatment process：
Hot dip galvanizing, spray coating and other processes can enhance corrosion resistance, and the service life of galvanized steel can reach 15-20 years
The C5 level anti-corrosion standard (suitable for environments such as salt spray and acid rain) is a key indicator for long-term durability.

Installation quality：
Professional installation ensures the stability and wind resistance of the bracket (such as designing wind speed resistance>42m/s), avoiding changes caused by improper installation
Form or damage.

Operating environment：
Corrosive environments such as coastal areas and high humidity may shorten the lifespan, while dry inland areas are more conducive to extending the service life

Measures to extend lifespan
Regular maintenance: Check the tightness of the bracket, the integrity of the coating, and promptly repair damaged or corroded parts
Anti corrosion treatment: Regularly apply anti-corrosion paint or supplement galvanized layer
Design optimization: Adopt design standards that comply with extreme weather conditions (wind and snow loads) that occur once every 50 years.
The durability of ground solar brackets can achieve a service life of over 20 years through material selection, process optimization, and standardized maintenance. Some high-quality products can reach up to 30 years under ideal conditions
