Container Roof Cover Systems
Curvco Steel buildings are the perfect solution for creating rooftops for Conex containers. Many companies are using shipping containers to create either permanent or temporary storage space. This is easy to accomplish with Curvco structures by adding a roof between two or more shipping containers. Metal roofs can be used to create that much-needed additional space. They can be designed to be portable and/or moveable. Our buildings can also easily be mounted to concrete walls for a roof system or pre-existing slab. If a custom size is required, our in-house engineering department will custom design one to meet your needs.
