Product Details, Specifications, and Technical Information

Aluminum Square Tube 3003 is a versatile structural component known for its good weldability, corrosion resistance, and moderate strength. Its square cross-section provides consistent flat surfaces, simplifying connections and offering stability in various applications. This non-heat-treatable alloy gains strength through cold working, making it suitable for lightweight frameworks, supports, and general fabrication. Common uses include furniture frames, sign supports, and architectural elements where a combination of strength and corrosion resistance is required.
