All new containers (and One-trip containers) are built to ISO standards for dry cargo and are fully weatherproofed. When you purchase a used cargo-worthy container, it has been carefully inspected and, if necessary, repaired to bring it back to a fully weatherproofed condition.
At our extensive modification facilities in Oakland and Wilmington, we carefully inspect containers for leaks, rust, and holes. The seals are checked for integrity and repaired or replaced as needed. Flooring is inspected and then repaired or replaced as needed with marine-grade plywood.
