Lighting poles installed on roads and in parks are exposed to rain, wind, and ultraviolet rays for extended periods, making surface treatment essential to prevent rust. A representative method for this is "galvanization," which involves covering the surface of the metal with a zinc coating. Galvanization not only protects iron from air and moisture but also ensures that if the surface gets scratched, the zinc will corrode before the iron, thereby protecting the steel. This treatment is crucial for enhancing the durability of lighting poles and reducing maintenance burdens. However, to achieve sufficient rust prevention, proper surface preparation before galvanization is also necessary. If burrs, oil, or dirt from processing remain, it can lead to uneven coating or peeling. Additionally, it is important to verify quality through thickness measurement and visual inspection after treatment. On the homepage of Kando Industrial, the reasons why galvanization is necessary for lighting poles, the mechanism of corrosion prevention, and key points for enhancing quality are explained in detail.

In the manufacturing of lighting poles, "deburring" is an important process that supports the safety and durability of the product. Burrs are small protrusions or sharp edges that occur when metal is cut, drilled, or welded. If burrs remain, they can lead to injuries for workers and users, as well as damage the insulation of wiring that runs through the pole, potentially causing electrical issues. Additionally, burrs can make it difficult for paint to adhere, leading to peeling and corrosion. They can also prevent parts from fitting together properly, resulting in extra labor during assembly and installation, which affects the quality and workability of the product. To finish properly, it is important to use a combination of machining and manual work tailored to the materials such as stainless steel, aluminum, and steel, as well as the thickness and shape of the parts. Even fine details that are difficult to process with machines are carefully finished by workers. Why does seemingly inconspicuous deburring influence the safety, lifespan, and aesthetic quality of lighting poles? Kandai Industry's website provides detailed explanations of the problems caused by burrs and the deburring methods suited to different materials and shapes.

By the end of 2027, the production and import/export of fluorescent lights will generally come to an end due to the "Minamata Convention." Outdoor lighting can still be used until it burns out, but caution is needed regarding accidents and security risks due to non-lighting, as well as potential shortages of materials and concentrated construction just before the deadline. This is where the "conversion adapter" comes into focus, which allows for the replacement of existing lighting poles with LED fixtures. This can sometimes enable the transition to LED lighting while keeping costs and construction time down compared to replacing the entire pole set. Are you thinking, "I have no choice but to replace poles that are still usable"? We provide detailed explanations on our website about transitioning outdoor lighting to LED using conversion adapters and points to prepare for the 2027 issue.
