Hot Finished Square Hollow Sections - 300x300x6.3

Hot-finished square hollow sections (SHS) are symmetrical, box-shaped steel tubes manufactured at very high temperatures to create a uniform and stress-free metal structure. Because they are shaped while red-hot, they do not suffer from the internal weaknesses that can happen during cold bending, making them highly reliable for heavy welding and tough structural jobs. Their square shape gives them equal strength and resistance to bending from all sides, while their flat faces make them very easy to cut and connect to other beams. These durable sections are a standard choice for heavy-duty building columns, portal frames, and large industrial structures.
