Resistant to salt damage, lightweight, and rot-proof! Incorporating VI manufacturing methods with a durability of over 50 years in mind.
We would like to introduce our GRP box girder bridge (VI method). Using the power of vacuum to inject resin into the fiberglass layer, the "VI method" ensures that the resin permeates thoroughly, creating a uniform and robust laminated material for the production of various parts (deck, side panels, girders, bottom plates, and bridge panels). To prevent any degradation of the laminated material's strength due to influences such as ultraviolet rays, water, or temperature changes, the bridge body is completely painted, aiming for easy maintenance. 【Functional Characteristics of the GRP Box Girder Bridge (VI Method)】 - Lightweight, allowing for consideration of utilizing existing foundations. - Long-term use with simple maintenance, enabling a reduction in maintenance costs. - The shape of the mold can be designed, allowing for the creation of elegantly curved girders. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
■FRP materials that are lightweight, have high strength per unit weight, are corrosion-resistant, and are strong against salt damage. ■Pin foundation bases that do not require the use of heavy machinery or excavation of the ground surface. Our company has introduced these two technologies ahead of other companies in Japan and boasts a wealth of construction achievements. We are involved in the design and construction of bridges, decks, boardwalks, and piers in national parks and theme parks that are well-known to everyone. By partnering with a Dutch company and introducing new technology using FRP materials, we have made it possible to construct long-span FRP bridges that were previously difficult to achieve. Furthermore, a durability of over 60 years is expected, making this a technology that can open up new markets in the future.
