Rectangular aluminum square tube

Aluminum square tube are hollow profiles with a square cross-section. They are manufactured through a process called extrusion, which forces molten aluminum through a die to form the desired shape. These tubes come in various sizes, with the dimensions referring to the width and depth of the square in inches (e.g., a 4×4 tube has a square cross-section measuring 4 inches on each side). The thickness of the tube wall, also known as the wall thickness, is another important factor that influences the strength and weight of the tube.
