Introduction
Round Steel Tube-also known as Circular Hollow Section (CHS)-is a precision‑formed structural element crafted from high‑quality carbon steel. Boasting uniform wall thickness and a smooth, cylindrical profile, round tubes offer excellent torsional strength, even load distribution, and an appealing aesthetic. Their versatility, combined with superior weldability and corrosion‑protection options, makes them ideal for applications spanning construction, automotive, furniture, and industrial equipment.
