Rectangular tubes
Standard Aluminum

Linkedalu’s rectangular aluminum tubes provide directional strength for beams, horizontal rails, and structural channels. Extruded from 6061-T6 or 6063-T5 alloys, they feature straight, parallel sides and good torsional stiffness. We manufacture a wide range of cross-sectional dimensions and wall thicknesses. Surface finishes include anodizing and PVDF coating for outdoor durability. Our Xiamen factory can supply long lengths, fabricated components, or bulk shipments. Choose our rectangular tube profiles for architectural grid systems, industrial frames, and transportation structures.
