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 corrosion-resistant design and post-construction management. 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 different types of metals do not come into direct contact can reduce the risk of corrosion through thoughtful design. 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. Kanda Industrial not only selects appropriate painting and plating based on the intended use but also provides design support to prevent corrosion, including drainage holes and corner treatments. Details about the causes of corrosion that cannot be completely prevented by rust treatment and eight design points for prolonging product life are explained in detail on Kanda Industrial's website.

Cutting in metal processing is not just a process of simply dividing materials. It is necessary to choose the appropriate method according to the type and thickness of the material, as well as the required precision, whether it be 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 construction stability and aesthetic consistency. Kanda Industries manufactures JIS-compliant steel poles and provides products with established design, construction, and inspection systems.
