What is the lifespan of a lighting pole?
The lifespan of lighting poles is influenced by the installation environment and materials used, with a general guideline of 15 to 30 years. When rust or corrosion reduces structural strength, it is considered time for replacement.
To extend lifespan, regular inspections along with the following three technologies are effective:
1. Applying zinc coating to iron poles to enhance corrosion resistance against salt damage and acid rain.
2. Adding a polyester coating over the zinc layer for further protection against UV rays and rainwater.
3. Regularly applying anti-rust paint to mitigate external damage. By combining these methods, durability is improved, and maintenance costs can be reduced.
Kandai Industries utilizes these processing technologies to provide long-lasting and reliable lighting poles.
