Easily meet flow, design life and structural requirements with site-specific steel culvert liners by InfraSteel
A common culvert rehabilitation challenge is finding a solution that meets strict flow capacity requirements, design-life requirements, and at the same time increases the structural integrity of the failing culvert where detours are impractical. InfraSteel designs and fabricates culvert lining systems that easily meet and often exceed these requirements.
Each culvert liner is designed to maximize the total water way area, thereby improving or preserving existing hydraulic conditions.
InfraSteel culvert liners are made using smooth wall carbon steel with a Manning’s Coefficient of .012.
Calculated design life to meet project requirements
Design life is built into the thickness of the steel. If a project owner wants a 70-year design life we add 70 years of sacrificial steel to the wall thickness of the liner. Destructive testing by Caltrans determined that ID coatings for stormwater applications are quickly removed by abrasion.
Superior structural integrity without the compromise
When structural integrity is a major concern, InfraSteel has the solution. InfraSteel’s steel culvert liners can be installed without disrupting traffic or rail operations. After joint welding, the end product will be one solid steel structure without the possibility of joint failure.
