●Significantly lighter compared to concrete coverings ●Contributes to shorter construction periods and improved workability ●Reduces damage to the floor slab with shock-dispersing structure
"Bridge Plus Alpha" is a road widening method using steel substructures. The lightweight substructure units offer excellent workability, and the factory-manufactured units enable a reduction in construction and regulation periods. It has been widely adopted in various bridges across the country, including the Enoshima Ohashi Bridge. Even for bridges that had to give up on widening due to increased dead load with traditional concrete substructures, "Bridge Plus Alpha" expands the possibilities for widening. Additionally, it can accommodate various functional additions such as drainage pits and lighting fixtures. Please feel free to contact us first. We will prepare and submit an estimate of reference sections, dead loads, material costs, and installation costs according to your requests. ● NETIS Registration Number: KT-230106-A
