Aluminum Triangular Tube 3003 is fabricated from a non-heat-treatable alloy known for its good weldability, corrosion resistance, and moderate strength. Its distinct triangular cross-section offers unique structural properties and aesthetic possibilities for various applications. This shape can provide increased rigidity in certain orientations compared to round tubing of similar weight. Common uses include lightweight framework, artistic installations, and specialized structural supports where a unique geometric profile is desired.
