Product Description
Description
This 3-inch × 3-inch × 14‑gauge square tubing is a lightweight yet durable structural steel box section designed for architectural framing, supports, gates, fencing, trailers, and general fabrication. The 14‑gauge (approx. 0.083") wall thickness provides a strong balance of rigidity and reduced weight, making it ideal for medium‑duty structural applications where ease of handling and clean aesthetics matter. The 20‑ft length allows for long, continuous spans with fewer welds, improving strength and fabrication efficiency. The smooth mill finish is ready for welding, painting, or powder coating.
