Square tubing (e.g., 2”x2”, 2.5”x2.5”, 3”x3”) offers uniform moment of inertia about both axes, simplifying load calculations. Flat sides facilitate bolted connections and welding, and square corners shed water and debris more effectively than round tube saddles.

When building a carport, you are protecting a valuable asset—your vehicle. Don't let a flimsy frame compromise that protection. By choosing , you ensure that your carport remains sturdy, rust-free, and visually appealing for decades to come.
This paper is intended for informational use by contractors, architects, and property owners. Always consult local building codes and a licensed structural engineer for specific design loads.
The defining characteristic is the hot-dip galvanizing process (ASTM A123). The tubing is cleaned via caustic degreasing and acid pickling, then fluxed in a zinc ammonium chloride solution. Finally, it is immersed in a bath of molten zinc at approximately 830°F (443°C). A metallurgical reaction occurs, forming iron-zinc intermetallic layers (Gamma, Delta, and Zeta) topped by a pure Eta zinc layer. This results in a coating thickness of 1.5 to 3.9 mils (45–100 microns), which is bonded at the molecular level—unlike simple paint or powder coating.
