According to a 2012 case study, one year after installing concrete pipe under a major highway, the Wisconsin Department of Transportation (DOT) found that the pipe already needed to be relined due to structural cracks. The DOT considered three different pipes and ultimately choose an Aluminized Steel Pipe to fit the project’s needs. Aluminized Steel was chosen due to the material’s strength, durability and sustainability. According to the report, this product was significantly more economical than that of two alternative products considered, and the contractor was able to reline the project in just seven days without any disruption to traffic.
