Stainless steel square tube is an extremely popular general purpose tubing material. The square shape makes it easier to work with, compared to its round tube counterpart, while maintaining the same structural integrity. They come in handy when working on trailers, frames, shelves and other ornamental projects. Although they are widely used in commercial settings, they do find important uses in industrial projects as well. All the steel tubes at our disposal are extremely reliable and sturdy, and conform to the quality standards laid out by the industry.
