Many American companies produce pre-cast concrete culverts including McPherson Concrete in Kansas, American Concrete in Maine, Jensen Pre-cast in California and Rinker Materials in Florida. The most common concrete culverts are box culverts because they are easy to transport and install, economical and can be manufactured with high standards of quality.
McPherson Concrete, one of the largest concrete manufacturers in the Midwest, offers more than 40 different sizes of box culverts from 4 feet by 3 feet to 14 feet by 14 feet. In addition, its website features a host of resources for researching concrete pipe structures.
American Concrete offers box culverts from 3 feet by 4 feet to 10 feet by 10 feet with a simple description of various advantages of box culverts. Jensen Pre-cast has three different styles of box culverts and more than 10 manufacturing locations throughout California, Arizona and Nevada.
Rinker Materials is the East Coast subsidiary of Cemex, the second largest concrete manufacturer in the world. Rinker has manufacturing plants in many states including Florida, Louisiana, North Carolina, Ohio and Pennsylvania among others. In addition to traditional sizes, Rinker offers a MegaBox concrete culvert that is large enough to be used as a bridge replacement.
