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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
