PC box culvert
Precast box culverts made of prestressed concrete according to the recommended specifications of JISA 5373 by the National Box Culvert Association.
By placing PC steel materials on the top and bottom plates, the thickness of the members can be reduced, resulting in a lighter weight compared to RC box culverts. Standard sizes range from width 1.8m × height 1.2m to width 5.0m × height 2.5m.
