Collection: Aluminum Square Tube is your source for high-performance and long-lasting aluminum square tubing. We combine high quality aluminum materials with state-of-the-art machining techniques to manufacture our heavy duty square aluminum tubing products. Builders of all types, from professional contractors to hobbyists to DIY enthusiasts, use our products to bring their designs to life, and it isn’t hard to see why. We use only the best-made raw materials and allow our talented and skilled engineers create our metal products to your exact specifications.

Our aluminum rectangular tubing is made from 6063 aluminum, which is often referred to as architectural aluminum. This is because it has a surface finish that is far smoother than other commercially available alloys, and because its strength is significantly less than many heavy aluminum alloys, making it far more suitable in situations where strength is not the foremost consideration. With consistent high ratings for forming, cold working operations, anodizing, and machining, our aluminum square tubing is second to none!
