Sturdy! Lightweight! Great scenery! A fiberglass stair deck with four strengths!
As an example of the construction of the "FRP Stair Deck," we introduce Nakagusuku Park (Pathway No. 2) in Okinawa Prefecture. Located at an elevation of 150 meters, it is designated as one of Japan's 100 Historic Castles, a UNESCO World Heritage site, and offers views of the Pacific Ocean and other scenic spots. To allow everyone to stroll through the park, plans were made for walking paths and observation decks. Due to its coastal location and strong ultraviolet rays, durable and salt-resistant FRP materials were chosen. 【Overview】 ■ Nakagusuku Park (Pathway No. 2) ■ Okinawa Prefecture, construction completed in June 2016 ■ W2.0m x L87.7m ■ W6.8m x L10.4m (Observation Deck) ■ Railing, floorboards, structure: FRP (pultruded material)

basic information
(1) Since it is a plastic reinforced with glass fibers, it is lighter and stronger compared to conventional structural materials! - Its weight is 1/4 that of steel, allowing for reductions in foundation construction costs and transportation expenses. - It can be manually transported and constructed even in remote mountainous areas where heavy machinery cannot access. (2) Resistant to salt damage and water, and does not corrode! - High corrosion resistance that does not rust or rot like wood or metal. - Contributes to the reduction of life cycle costs. (3) Excellent weather resistance as deterioration from UV rays and wind and rain can be suppressed by surface coating! - Compared to general plastics, it can suppress deterioration from UV rays and wind and rain. - Contributes to the reduction of life cycle costs. (4) Good aesthetic appeal! - Color selection is possible due to surface coating. - New techniques allow the bridge structure to be arched.

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.
