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!

Lighting poles are utilized not only for their basic functions such as streetlights, park lighting, and parking lot illumination, but also as mounting bases for security cameras, advertising and information boards, sensor devices like noise meters and traffic counters, as well as supports for event flags and decorations, making them multipurpose. A significant advantage is that repurposing existing poles eliminates the need for additional installation space, achieving both cost reduction for equipment installation and landscape preservation. Furthermore, in recent years, the integration of smart poles that combine Wi-Fi antennas, charging stations, and facial recognition systems has progressed, contributing to the efficiency of urban spaces and enhancing safety and comfort.

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.
