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 determined to be time for replacement. In addition to regular inspections, the following three technologies are effective for extending lifespan: 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 suppress external damage. By combining these methods, durability is improved, and maintenance costs can be reduced. Kandai Industry utilizes these processing technologies to provide long-lasting and highly reliable lighting poles. For more detailed explanations, visit Kandai Industry's website!

Lighting poles are mainly made of steel or aluminum, and their lifespan varies depending on the usage environment, materials, and maintenance conditions. Steel is prone to rust, and as the paint deteriorates, its corrosion resistance decreases, shortening its lifespan. On the other hand, aluminum is lightweight and has excellent corrosion resistance, but it also has limitations in terms of strength. The installation environment also affects lifespan. In high-corrosion-risk environments such as coastal areas or industrial zones, deterioration occurs more quickly, and designs must withstand natural conditions like wind pressure and earthquakes. Additionally, ground subsidence of the foundation can compromise the verticality and stability of the pole, leading to deterioration. Regular inspections and maintenance help in the early detection of rust, paint peeling, and loosening. Delayed action can significantly compromise safety. If deterioration progresses and issues arise with functionality or safety, replacement becomes necessary. In such cases, it is important to select appropriate poles considering material selection, installation environment, and maintenance plans to maintain reliable lighting equipment over the long term.

Outdoor lighting poles require a paint that combines aesthetics and durability. There are four important points to consider: 1. **Proper Paint Selection** Polyurethane and epoxy paints, which are excellent in weather resistance and corrosion resistance, are recommended to maintain aesthetics over the long term in outdoor environments. 2. **Importance of Surface Treatment** It is essential to thoroughly remove rust, old paint, and dirt. By preparing the substrate meticulously through sandblasting or chemical treatment, the adhesion and lifespan of the paint are improved. 3. **Management of Construction Environment** Weather conditions such as temperature, humidity, and wind speed affect the drying and curing of the paint. Proper management of these factors and conducting the work in a well-ventilated area can prevent unevenness and deterioration of quality. 4. **Regular Maintenance** Regularly inspect the condition of the paint film, and promptly repair any cracks, peeling, or rust found. This allows for the extension of the pole's lifespan and the maintenance of its appearance. **Summary:** The painting of lighting poles is a systematic process involving "paint selection" → "substrate preparation" → "proper application" → "regular repairs," which balances beauty and durability, preserving the landscape value of public roads and facilities for a long time.
