Square

The square structural shape is a solid, continuous form defined by four equal-length sides meeting at right angles. Unlike hollow or tubular profiles, this square is completely filled throughout—imagine a solid block of material, such as concrete, with no voids or inner cavities. Its uniform geometry makes it easy to manufacture and calculate, offering consistent strength in both vertical and horizontal directions. The shape provides strong resistance to compressive forces, making it ideal for load-bearing columns, piers, or foundational supports in construction. Its simplicity and stability allow it to transfer loads evenly, and when made from dense materials like concrete, it also offers good resistance to bending and buckling under pressure.
