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.

The quality of lighting poles is significantly related not only to their aesthetic appeal but also to safety and durability. Since these products are exposed to wind, rain, and ultraviolet rays outdoors, it is crucial to accurately process the materials and join them while maintaining strength. Laser cutting is characterized by its ability to process complex shapes and fine holes with high precision based on CAD data, while minimizing burrs and dimensional errors on the cut surfaces. When the components fit together accurately, it also leads to improved assembly precision and the overall finish of the product. Additionally, laser welding is a technology that can firmly join metals while minimizing distortion and deformation caused by heat. However, to achieve high-quality processing, it is essential not only to have the performance of the equipment but also the knowledge and experience of technicians to set conditions according to the materials and shapes. What specific benefits do laser cutting and laser welding provide in supporting the safety and durability of lighting poles? On the homepage of Kando Industry, you can find a more detailed explanation of the importance of laser processing in the production of lighting poles.

One of the important processes that affects the quality of metal products is the "finishing" that takes place after processing. Finishing includes various methods such as polishing and grinding to smooth the surface, deburring to remove protrusions caused by cutting or processing, chamfering to shape corners, and painting or plating to enhance corrosion resistance and aesthetics. It is a crucial process that not only beautifies the appearance but also improves the safety, durability, and dimensional accuracy of the product. However, to create high-quality products, it is not enough to just carefully perform the final finishing. Ensuring precision in the earlier processes such as material selection, design, cutting, bending, and welding, along with conducting inspections at each stage, leads to a clean and stable finish. At Kanda Industry, we value processing precision before finishing, inter-process collaboration, and quality confirmation, and we are committed to manufacturing that considers the functionality, aesthetics, and safety required for our products. We provide detailed explanations of representative finishing methods in metal processing and points to pay attention to in earlier processes to enhance final quality on Kanda Industry's website.

To ensure the longevity of metal products used outdoors, it is important to consider not only rust prevention treatments such as painting and plating but also designs that are resistant to corrosion and management after construction. For example, incorporating drainage holes to prevent rainwater accumulation inside the product, eliminating sharp corners that are difficult for paint to adhere to, and ensuring that different types of metals do not come into direct contact can reduce the risk of corrosion through thoughtful design during the planning stage. Additionally, proper on-site responses, such as repairing scratches that occur during construction and being mindful of paint film cracking when tightening bolts, also affect the product's lifespan. Considering rust prevention treatments, design, and construction management as a cohesive approach leads to improved durability of metal products and reduced maintenance costs. Kandai Industry not only selects appropriate painting and plating according to the application but also provides design support to prevent corrosion, such as the treatment of drainage holes and corners. The causes of corrosion that cannot be completely prevented by rust treatment alone and eight design points for prolonging product life are explained in detail on Kandai Industry's website.

Cutting in metal processing is not merely a process of dividing materials. It is necessary to choose the appropriate method according to the type and thickness of the material and the required precision, such as laser cutting, plasma cutting, or mechanical cutting. Additionally, fine adjustments of conditions during cutting and management of distortion due to heat greatly depend on the experience and skills of the operator. How does high-quality cutting affect subsequent welding, bending processes, and the quality of the final product? For more detailed explanations, please visit the Kando Industrial website!

The JIS standard (JIL1001) of the Japan Lighting Manufacturers Association specifies the material, structure, surface treatment, and inspection methods for steel tapered poles installed on roads and sidewalks. In terms of material, steel (thick steel plates) is used, considering fatigue strength, impact resistance, and corrosion resistance. High strength and ductility are required. Regarding structure, a design with cylindrical or conical cross-sections that can withstand load tests (such as wind pressure and earthquakes) is necessary. For surface treatment, hot-dip galvanizing plus painting or cationic electrodeposition coating is standard to prevent rust, and a continuous coating is important. The inspection system covers in-process inspections during manufacturing, measurement of dimensions and coating thickness upon acceptance, and submission of test reports for certification. By thoroughly implementing materials and quality control in accordance with these JIS standards, safety, durability, and reliability are ensured, securing stability in construction and consistency in aesthetics. Kanda Industries manufactures JIS-compliant steel poles and provides products with established design, construction, and inspection systems.

To safely install lighting poles, it is essential to perform strength calculations to prevent collapse or damage from external forces such as wind. First, based on local weather data, we assume the wind strength and set the required strength. 1. Wind pressure calculation - Calculate the pressure based on wind speed and direction, as well as the shape and height of the pole. 2. Material and cross-section evaluation - Verify the tensile, compressive, and bending strength of the materials and shapes used to ensure they can withstand the specified load. The design applies the standard JIL1003 for lighting poles to ensure safety and performance. Accurate calculations and appropriate pole selection are key to preventing accidents and extending lifespan. For more detailed explanations, please visit the Kando Industry website!

When choosing outdoor lighting poles, first pay attention to the "material" and "processing technology." Stainless steel and aluminum, which are resistant to rust and lightweight, can be used for a long time and are easy to install. Additionally, laser cutting allows for intricate designs, and advancements in welding technology have significantly increased the strength of the poles themselves. As a result, quality improves and maintenance efforts are reduced. By understanding the characteristics of the materials and processing methods, and selecting a pole that suits the installation location, you can ensure safety and cost-effectiveness. By the way, Kanda Kogyo offers lighting poles that combine high-quality materials with cutting-edge processing to meet a variety of needs.

Metal components such as outdoor lighting and road signs must possess the quality to function safely over long periods in harsh environments like rain, wind, and ultraviolet rays. The foundation of high quality lies in three key elements: 1. Precision design, advanced processing technology, and appropriate material selection 2. Strict process management and skilled workers 3. A quality control system equipped with inspection systems, measurement technology, and traceability. In cutting, dimensional accuracy and smooth cutting surfaces are crucial; in bending, angle accuracy and uniformity of shape are essential; and in welding, joint strength and beautiful beads are particularly important. By organically linking these aspects, metal products that combine durability and reliability are created. For more detailed explanations, visit the Kando Industrial website!

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.
