Core technical metrics and material behaviors defined for galvanized steel secondary structures.
Built with structural galvanized steel coated in heavy zinc to resist galvanic rust. Supports choices of standard 14-gauge (2.5" tubing) or heavy-duty 12-gauge (2.25" tubing).
12-gauge heavy-duty steel tubing features thicker walls that provide greater tensile strength, validated with a 20-year structural rust-through guarantee.
Frames are pre-engineered for rapid, square assembly. Anchoring tolerances require the concrete slab foundation to be flat and level within 3 inches.
Standard sizes utilize 5-foot length increments (e.g., 20', 25', 30') and leg heights up to 20' to accommodate custom RVs, lifts, and residential garage clearances.
Pre-engineered assemblies support standard load certifications of up to 140 MPH wind speeds and 30 PSF snow loads. Additional bracing is recommended in mountain zones.
Available in regular curved eave, boxed-eave horizontal, or vertical roof panels. Vertical panels run ridge-to-eave to prevent dirt and rain pooling.
