The metal road construction method is suitable for road construction in mountainous areas. It is a three-dimensional frame prefabricated bridge consisting of a grid section and a floor slab, primarily made of steel pipes and H-shaped steel.

The "Metal Road Construction Method" is a three-dimensional frame prefabricated bridge where the piles, cross beams, and main beams are rigidly connected at the grid points. It is mainly suitable for road construction on steep slopes in mountainous areas. We apply the appropriate structural type according to the terrain and construction conditions. We offer various types, including the "Widening Type," "Mountain Side Cantilever Type," and "Independent Type." 【Features】 ■ Excellent seismic resistance ■ Easy transportation and installation of components ■ Short on-site construction period ■ Widening possible while ensuring existing traffic ■ Consideration for the natural environment ■ Abundant track record *For more details, please refer to the PDF materials or feel free to contact us.

This is a reinforcement method for RC members using lattice steel plates (steel plates processed in a lattice shape). The reinforcement cross-section can be made thin, and it can reduce labor on-site.

Grid metal is a product that reinforces deteriorated RC structures by integrating with polymer cement mortar. By processing steel plates into a lattice shape, it allows for a thinner reinforcement layer, making on-site work more efficient. It is used for reinforcing the underside and topside of bridge RC slabs, repairing and reinforcing deteriorated box culverts, and reinforcing RC beams. By reducing the thickness of repairs, it enables a reduction in repair loads and ensures the maintenance of internal space. Features of the grid metal method: - It can be processed in the factory to match the shapes of tunnels and box culverts, thus streamlining on-site construction. - Since the vertical and horizontal bars are on the same plane, the reinforcement cross-section can be made thinner, minimizing the increase in dead load and favorably securing internal space. - By applying corrosion protection treatments such as hot-dip galvanizing and epoxy resin coating, it excels in corrosion resistance and contributes to the longevity of structures.

"ROBO TUBE" is a microtube with 1D/2D code that achieves excellent sealing and fitting properties. By integrating polypropylene and thermoplastic elastomer through one-shot molding, it realizes superior sealing and fitting. Compared to conventional microtubes, the opening and closing of the cap is very smooth, reducing the stress of cap operation. 【Features】 ■ The opening and closing of the cap is very smooth compared to conventional microtubes ■ Reduces the stress of cap operation ■ Innovative two-color molding of polypropylene and thermoplastic elastomer ■ Achieves excellent sealing and fitting properties ■ High compatibility with lab automation *For more details, please download the PDF or feel free to contact us.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.

In battery manufacturing lines, if components containing copper are used, there is a possibility that metal powder may mix in, dissolve, ionize, and pass through the separator, causing a malfunction that connects the positive and negative electrodes. Such minute metal powders may not be detected during pre-shipment inspections, and even if they are found, they can lead to various issues, such as the need to increase inspection processes to detect them. Therefore, Fukuda has developed a copper-free (all stainless steel) air leak tester that can be safely used in the production lines of battery manufacturers and secondary battery manufacturing equipment manufacturers.
