The catalog for the fire-resistant laminated wood "Moen Gen" has been updated as of April 2026. Why doesn't it drip? Why is it resistant to efflorescence? What about reducing life cycle costs? What are the installation methods? We have answered these questions from everyone. In addition to use in semi-outdoor eaves and skeleton ceilings, there are steadily increasing examples of adoption in places where the use of other fire-resistant woods is difficult, such as ceilings in bathroom facilities. "Moen Gen" uses a natural, penetrating type of paint, which retains the scent and texture of the wood, and if minor efflorescence occurs, it can be easily treated unlike urethane coatings. Additionally, since it is laminated wood, disadvantages such as shrinkage and warping are reduced, improving the maintenance of the building. We have also obtained ministerial certification with the coating, eliminating the need for on-site painting and reducing the burden. The basic colors are available in a rich variety of 27 colors that enhance the texture of the wood. *Custom color matching is also possible. 【Features】 ■ Numerous adoption records in eaves and skeleton ceilings ■ Improved maintenance of buildings ■ No dripping and strong against efflorescence ■ 27 color variations to choose from ■ Easy-to-use fire-resistant wood certified with paint

Did you know that there are various types of lighting poles tailored to their use and installation location? Here, we will explain mainly three types: "high ceiling floodlights," "streetlights and road lights," and "architectural exterior lighting." High ceiling floodlights: Used in indoor spaces such as sports facilities and warehouses where high ceilings are necessary, they require durability and strong illumination to reach far distances. Streetlights and road lights: Installed on sidewalks and roads to enhance safety. Streetlights are designed for uniform diffusion, while road lights are designed to make lanes and intersections easily recognizable. Architectural exterior lighting: Used for beautifying the appearance of facilities and buildings while also serving as nighttime security, often featuring highly designed types such as tapered poles. It is important to equip lighting poles with the optimal materials, shapes, and weather resistance according to their use and installation location. Kanda Industrial provides lighting poles suited for these purposes. For more detailed explanations, please visit Kanda Industrial's website through the related link.

The benefits of converting outdoor lighting to LED include a significant reduction in power consumption compared to traditional lighting. This contributes to reducing environmental impact and lowering electricity costs, and furthermore, the Ministry of Land, Infrastructure, Transport and Tourism and local governments support the transition to LED through subsidy and grant programs. When switching to LED, it is important to focus not only on the lighting fixtures themselves but also on the supporting lighting poles. If the existing poles are sufficiently durable, it is possible to replace them with LED fixtures at a low cost using conversion adapters. On the other hand, if the poles are aging, it is necessary to update them entirely while considering the landscape and harmony with the surroundings. Factors such as height, tilt, design, weather resistance, and maintenance are crucial in the design phase for new installations. It is recommended that the contractor evaluates the condition of the existing poles while utilizing support programs from the national and local governments to consider the optimal response method. A comprehensive assessment of the quality of light, costs, and maintenance management resulting from the LED conversion will be the key to success.

Metal cutting is not only about separating materials but is also a crucial process that affects product quality and cost. This article introduces the main methods. 1. Laser cutting: Non-contact, high precision, capable of handling complex shapes and thin to medium-thick plates, achieving smooth cross-sections. 2. Plasma cutting: Can process thick plates at high speeds and is cost-effective, though the cross-section is somewhat rough. 3. Mechanical cutting: Strong in cutting large and extremely thick materials or mass cutting using band saws and shearing. 4. Water jet cutting: Zero thermal impact, suitable for hard materials and precision parts. It emphasizes that the skills of experienced craftsmen who can discern metal properties, fine-tune conditions, and minimize distortion are essential. High-quality cutting directly leads to reduced assembly labor, automation of subsequent processes, reduced defects, and improved reliability, making the selection of a trustworthy contractor key. Kanda Industrial concludes by proposing the optimal cutting methods based on their extensive experience and technology. For more detailed explanations, visit Kanda Industrial's website!

Outdoor lighting poles require a paint that combines aesthetics and durability. There are four important points to consider: 1. **Proper Paint Selection** Polyurethane and epoxy paints, which are excellent in weather resistance and corrosion resistance, are recommended to maintain aesthetics over the long term in outdoor environments. 2. **Importance of Surface Treatment** It is essential to thoroughly remove rust, old paint, and dirt. By preparing the substrate meticulously through sandblasting or chemical treatment, the adhesion and lifespan of the paint are improved. 3. **Management of Construction Environment** Weather conditions such as temperature, humidity, and wind speed affect the drying and curing of the paint. Proper management of these factors and conducting the work in a well-ventilated area can prevent unevenness and deterioration of quality. 4. **Regular Maintenance** Regularly inspect the condition of the paint film, and promptly repair any cracks, peeling, or rust found. This allows for the extension of the pole's lifespan and the maintenance of its appearance. **Summary:** The painting of lighting poles is a systematic process involving "paint selection" → "substrate preparation" → "proper application" → "regular repairs," which balances beauty and durability, preserving the landscape value of public roads and facilities for a long time.
