Square steel tubing pricing depends on size, wall thickness, quantity, and current market conditions. Smaller sizes and single-piece orders carry higher per-foot costs, while bulk orders qualify for commercial pricing. Contact our sales team directly for a current quote on your specific requirements.

Yes. We process both standard and high-volume commercial orders at our Miami facility. Whether you need precision-cut 2x2 steel square tubing for frames or heavy-duty 4x4 steel square tubing for structural columns, custom lengths are available across all standard grades to meet your project timeline.

Standard options include hot-rolled mill finish, cold-drawn finish, shop-primed, and hot-dip galvanized. Mill finishes are typical for interior and painted applications. For outdoor or high-moisture environments, galvanized finish provides long-term corrosion resistance without additional coating requirements.

Square tubing is manufactured to structural dimensional tolerances — wall thickness, outside dimensions, and straightness are the governing specifications. Square pipe is produced to pressure and flow specs, with inside diameter and wall uniformity as the primary controls. For structural and fabrication applications, square tubing is the correct product.

ASTM A500 Grade B is the most common grade for structural hollow sections used in construction. ASTM A513 is used for mechanical and precision fabrication applications. Confirm the applicable specification with your structural engineer before placing an order for load-bearing use.

Yes. Hot-dip galvanized square tube is stocked for applications where corrosion resistance is required — exterior fencing, marine-adjacent structures, and outdoor equipment frames. The zinc coating extends service life significantly in South Florida's climate. Custom galvanizing on cut-to-length orders is also available; contact us for lead times.
