A-One Steel MS square hollow section is manufactured from high-quality steel processed through pickling, cold reduction and forming to deliver clean surfaces, consistent wall thickness and reliable mechanical performance. The section in nominal size 40×40 mm with approximately 3 mm wall thickness and 6 m length in YST 240 grade offers an efficient combination of strength, rigidity and weight for structural and fabrication use.The tubes are produced on modern mills with controlled galvanizing or protective finish options, ensuring good corrosion resistance and long service life in diverse site conditions.

Key Features

• Manufactured on high-capacity mills with consistent section geometry and straightness
• Good strength levels with balanced ductility for welding, cutting and fabrication
• Square profile 40×40 mm offering uniform strength and stiffness in both axes
• Wall thickness around 3 mm optimised for structural efficiency and weight control
• Clean outer surface suitable for painting, powder coating or galvanizing as required
• Closed hollow shape offering better torsional rigidity and buckling resistance than comparable open sections

Typical Applications

• Industrial sheds, warehouses and factory buildings
• Columns, beams and bracing members in structural frameworks
• Architectural frames, façades and space frames
• Railing, gates and boundary structures
• Support structures for solar, signage and general utilities
