The "Prestressed Deck 1.0m × 4.0m" is a new type of cover slab that has been elongated to 4.0m by adopting the steel plate prestressed reinforcement method. Even with an opening width of 4.0m, there is no need for intermediate girders, achieving unprecedented high work efficiency. Of course, it has sufficient strength against the B live load (T-25) specified in the road bridge guidelines, while maintaining the same specifications (height 200mm, width 1.0m) as conventional products, ensuring high compatibility with existing products. 【Features】 ■ Allows for a wide working space ■ Reduces excavation at the ends when installing girders ■ Work can begin immediately after removal ■ Suitable for structures with minimal soil cover ■ No need for notching of retaining walls *For more details, please download the PDF or feel free to contact us.
