CHS: Welding a circular section can be more challenging than welding square sections due to the curved geometry. Welding techniques specific to curved surfaces may be required.
SHS: Square sections have flat surfaces and right angles, which make them relatively easier to weld and fabricate.
CHS: Circular sections distribute loads uniformly in all directions, making them well-suited for applications where radial or torsional stress might be a concern, such as columns, posts, or in the design of circular structures.
SHS: Square sections are suitable for applications where loads act predominantly in horizontal and vertical directions. They are often used for beams, frames, and other structures with right angles.
