Hollow Structural Sections, or HSS, are metal profiles that have a hollow interior cross-section.
They are typically used in construction to create large open spaces. They are generally made of carbon steel, aluminum, and stainless steel. HSS has many applications in construction and manufacturing due to its high strength-to-weight ratio and versatility.
Common Applications
Hollow structural sections (HSS) are commonly used in various applications, including steel frames and columns, support beams, scaffolding, fencing and guardrails, platforms and decking, bridges, staircases, gates, trusses, and hydraulic platforms. Their versatility and strength make them a popular choice for many constructions and engineering projects. HSS is also often used in the automotive and aerospace industries.
The advantages and benefits of using HSS:
-They are lighter, which makes them easier to transport and install.
-They are stronger than other construction profiles, making them more durable; Hollow Structural Sections can support more weight than traditional solid profiles.
-They have high corrosion resistance and galvanized or stainless steel hollow Structural Sections are less likely to corrode or rust over time, making them a more durable option. Which makes them more resistant to damage from the elements.
How are hollow sections made?
Hollow sections are made through two main processing ways: the seamless process and the welded process.
Seamless Hollow Structural Sections are made through a process of extrusion. Molten steel is forced through a die to create a hollow profile. The profile is then cooled and trimmed to the desired size and shape.
The welding tube manufacturing begins by cutting steel plates into the desired shape. The plates are then welded together to create a tube or pipe. The welds are then ground down and polished to create a smooth surface. Finally, the tube is cut into shorter sections, and holes are punched in the ends.
