The "Lightweight Square Support Column" is a long-selling product with a history of over 40 years, ensuring safety and reliability. It is an assembled steel column used when a vertical load of 20 tons is required. With a permissible load of 196 kN (20 tons), it allows for a wider working space compared to standard support structures. Additionally, it can accommodate various heights through a combination of six different sizes ranging from 200mm to 3000mm. It can be used more easily than H-beams (raw materials or retaining materials), significantly improving workability. More details are available in related products and catalogs.

"Step Guard," a stair opening handrail used to prevent falls from stair openings. The "Aluminum Step Guard" is a stair opening handrail that has been reduced in weight by about 60% compared to traditional steel products, weighing only 6.2 kg. We have now obtained certification from the Temporary Construction Association and are finally able to offer it to our customers. Please give it a try. You will surely be surprised by its incredible lightness! *Related products and catalogs provide more detailed information.

The conventional "step guard" was very heavy, causing significant burdens on-site. The new product, the aluminum step guard for stair openings, has switched the main material from steel to aluminum, achieving a weight reduction from 14.8 kg to 7.8 kg, approximately 47% lighter. This dramatically reduces the burden on the worksite and significantly improves work efficiency, contributing to shorter construction periods. Additionally, the arm can be opened and closed at a 90-degree angle, eliminating the previously existing triangular opening and greatly enhancing safety. More details are available in related products and catalogs. 【Features】 ■ Wedge-locked scaffolding (next-generation scaffolding) ■ Proven track record with major leasing companies ■ Hook locking mechanism improves efficiency in disassembly with one-sided operation ■ Prevents falls from stair openings ■ Certified compliant product by the Temporary Construction Industry Association

In sites where large spans are required, a significant amount of labor is needed, resulting in very high costs. However, by using the "Multi Truss B," a joint-type truss material for large spans from Chuo Built Industry, it is possible to achieve substantial cost reductions in labor expenses and shorten construction periods in sites that require large spans, such as "temporary roofs," "work stages," and "temporary walkways." The "Multi Truss B" has fewer components compared to conventional methods and features a simple design that allows for easy assembly with minimal labor by inserting pins to use it as a unit. Currently, we are providing materials with case studies. Please download the PDF below.

Temporary soundproof panels used in demolition work. Despite the need for robustness, conventional products had weak corners, leading to damage or deformation that rendered them unusable, resulting in repair costs. To solve these issues, demolition professionals developed the temporary soundproof panel "Noise Guard." By adopting aluminum die-casting for the corner pieces, high strength and high rigidity have been achieved. Not only is it sturdy and resistant to breakage, but it also allows for partial repairs that were previously difficult, contributing to cost reduction.

The only large ceiling fan made in Japan, "THE FIRST FAN," is effective for condensation prevention on floors and products in warehouses, factories, and workspaces. Its power consumption is equivalent to that of a household hairdryer, with electricity costs around 245 yen per day. It can be directly mounted to the ceiling, making it possible to install even with ceiling cranes present.

In the future, it is expected that renovation work will significantly increase, particularly in the metropolitan area. Especially in renovation projects such as condominiums, consideration for residents and users is essential, unlike in new construction or demolition work. Therefore, we would like to introduce the "Sky Fence," a protective frame that is aesthetically pleasing and safe to touch, making it ideal for renovation work. The "Sky Fence," made from high-tensile steel plates with a punching process, is flat and does not have the protrusions found in traditional protective frames made from expanded metal, ensuring safety even if residents or small children accidentally touch it during condominium renovation work. Additionally, it is visually appealing and does not detract from the urban landscape. In response to customer feedback regarding deformation during demolition and crushing when stacked, we have released a renewed product that incorporates aluminum reinforcements into the frame, achieving greater strength. We also offer options for frame scaffolding and wedge-locked scaffolding (next-generation scaffolding). Please feel free to contact us.
