1570 licensed Structural Steel Contractors in California
What Does a C-51 License Cover?
Fabricates and erects structural steel shapes and plates used as structural members for buildings and structures, including riveting, welding, rigging, and metal roofing systems.
Hiring a Structural Steel Contractor
Structural steel work requires permits and engineering review. Verify the contractor has experience with the specific type of structural system being installed and that all connections will be inspected per the approved plans.
California law requires a contractor license for this type of work on projects valued at $500 or more (combined labor and materials). Hiring an unlicensed contractor for work requiring a license may void your consumer protections.
