14 ga galvanized square tubing — 2.25″×2.25″ and 2.5″×2.5″ — held square, diamond-cut, bundled on wood slats, and delivered truckload after truckload from Mansfield, Ohio.
Carport and metal building frames run on two sizes of tube, and the builders who win are the ones whose steel shows up — square, on time, in volume. This is among the highest-volume product we make: five ERW mills fed by our own 72″ slitter and thousands of tons of master coil, so the supply chain from coil to frame section lives under one roof.
Requirements our carport customers spec — squareness held, diamond-cut ends, blow-out after saw cut, anti-corrosion treatment — are part of the run, not extras. Spec: ASTM A513; see the square tubing page for the full size envelope.
The industry standard is 14 ga galvanized square tube in 2.25″×2.25″ and 2.5″×2.5″ — the frame sections carport and metal building manufacturers run by the truckload. We produce both sizes in volume, with G60 Grade 50 and anti-corrosion treatment available per spec.
Squareness is the acceptance standard our carport customers write — frames won't assemble from out-of-square tube — so it's checked as part of the run, with diamond-cut ends per spec.
Per customer spec: typically 50-piece bundles with wood slats between layers, lengths under 32 ft, loaded for the receiving equipment on your yard. Standing truckload programs keep high-volume builders supplied week after week.
Yes — carport-frame square tube is among the highest-volume products we run, on five ERW mills fed by our in-house 72″ slitter and master coil inventory. Minimum order is a truckload, roughly 45,000 lb.
