A well-built residential metal structure can last 30–50 years or more in Texas, especially with proper coating, anchoring, and maintenance. Steel structures are designed to resist rust, wind, and intense sun when installed with quality materials.
Most Texas counties and cities require a building permit for permanent metal structures, especially if attached to a home or built on a concrete foundation. We handle all permitting, zoning compliance, and structural engineering for your area, whether you're in San Antonio, Austin, Dallas, or Houston.
That depends on the structure. For fully enclosed buildings, workshops, and garages, we recommend a concrete foundation or slab. Carports, open structures, and fences can often be installed with pier footings or anchor systems, depending on soil and homeowner preference.
