寛大工業 Company Overview

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!
