Streetlights that illuminate pathways, parking lots, and parks are important facilities that support our safety and peace of mind. Streetlights installed on public roads are mainly managed by local governments and are intended for crime prevention and traffic safety. On the other hand, streetlights in commercial facilities and private properties not only ensure the safety of users but also contribute to enhancing the landscape and attracting customers. By installing streetlights, nighttime visibility is improved, leading to an environment where crimes are less likely to occur. Furthermore, in recent years, energy-efficient LED lighting and smart poles that provide lighting for evacuation routes, charging, and Wi-Fi during disasters have emerged. To maintain the effectiveness of streetlights over time, the strength and durability of the poles supporting the lighting fixtures are also essential. For more information on the types of streetlights, their installation benefits, and the role of lighting poles, please refer to the related links.

Lighting poles installed on roads and in parks are exposed to rain, wind, and ultraviolet rays for long 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, measuring the film thickness and conducting visual inspections after treatment are important for confirming quality. Kandai Industry's website provides a detailed explanation of the reasons why galvanization is necessary for lighting poles, the mechanism of corrosion prevention, and key points for enhancing quality.

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 running 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 essential to differentiate between machine processing and manual work according to the material, thickness, and shape of the parts, such as stainless steel, aluminum, and steel. 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 appropriate deburring methods based on materials and shapes.
