          Steel corrugated culvert is a high-quality highway building material that replaces round pipe culverts, cover culverts and small bridges. The product has the advantages of short construction period, light weight, convenient installation, good durability, low factory cost, strong resistance to deformation, and reduced maintenance costs after opening to traffic. It is suitable for high-cold frozen soil areas, soft soil road base belts and deep fill soil belts. It can save a lot of money and has obvious economic benefits.
