"Salt damage resistant, lightweight! High strength and rot-proof" FRP bridges and walkways.
Sturdy! Lightweight! Corrosion-resistant! Excellent in aesthetics! Utilizing these four features, FRP bridges and walkways are actively used in various scenes!
We introduce bridges and walkways made of "FRP (Fiber Reinforced Plastic)," which excels in strength, lightweight properties, and corrosion resistance. The weight of FRP is about 1/4 that of steel, allowing for reduced foundation construction costs and transportation expenses. It can be manually transported and constructed in locations such as mountainous areas where construction machinery cannot be used. It is resistant to corrosion from rain, wind, and salt damage, demonstrating excellent durability even in harsh environments, contributing to reduced lifecycle costs. FRP bridges and walkways can also be effective against salt damage from coastal areas as well as salt damage caused by freezing agents! 【Four Features】 1. Reinforced with glass fibers and other materials, it is lighter and stronger compared to conventional structural materials. 2. Resistant to salt and moisture, it does not corrode. 3. Capable of suppressing degradation from UV rays and wind, it has good weather resistance. 4. Can be painted to match the surrounding colors, harmonizing with the natural environment. *You can view a catalog featuring numerous construction examples from the "Download" section.

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 heavy machinery and do not need 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, which 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.
