Product Description
Description
This 4-inch × 4-inch × 11‑gauge square tubing is a strong, weldable structural steel tube designed for heavy‑duty framing, equipment supports, gates, trailers, fabrication projects, and general construction. The 11‑gauge (approx. 0.120") wall thickness provides excellent rigidity and load‑bearing strength while remaining workable for cutting, welding, and machining. The 20‑ft length allows for long, continuous structural spans with fewer welds, improving overall stability and fabrication efficiency. The smooth mill finish is ready for welding, painting, or powder coating.
