Reliable Secondary Containment

Steffes Secondary Containment Systems are designed to meet regulatory requirements and are built to last. Each system is manufactured from 12-gauge galvanized steel and finished with durable powder coat paint for protection against extreme weather conditions.

The secure, bolt-together panels allow flexibility for many configurations and reduce installation time. We offer post and post-less systems that can be ordered in full and half panel construction, designed for various configurations.

Steffes walkovers also work well with both systems to provide a safe way to step over the containment wall.
