Product Details
Rectangular and Square Tubing Rectangular and square tubing, classified as hollow structural sections (HSS), are precision-engineered metal profiles with rectangular or square cross-sections.
Manufactured primarily from carbon steel or alloys, these tubes are formed through cold-rolling or high-frequency resistance welding processes, ensuring dimensional accuracy and structural integrity.
