Square Tubes: A Comprehensive Guide

Square tubing is a hollow, square-shaped metal tube with uniform sides and a defined cross-sectional shape. This uniformity in shape sets it apart from other types of tubing, such as round or rectangular tubing. Square tubes are typically made from materials like steel, aluminum, stainless steel, or even plastics. The manufacturing process involves forming a flat strip of the chosen material into a square shape and welding the edges together to create a seamless, rigid structure.
