寛大工業 Company Overview

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.
