Steel Sections

Steel sections are fundamental components in construction and manufacturing, providing strength, durability, and versatility across various applications. These structural elements are produced in various shapes and sizes to meet specific engineering and architectural needs. Steel sections form the backbone of countless infrastructure and industrial projects, whether used in buildings, bridges, machinery, or vehicles.

Steel sections are typically categorised by their cross-sectional shapes. The most common types include I-beams (also known as H-beams or universal beams), angles (L-sections), channels (C-sections), T-sections, and hollow structural sections (HSS), such as rectangular, square, and circular tubes. Each type serves a different purpose and offers unique load-bearing characteristics.

For example, I-beams are widely used in construction due to their high strength-to-weight ratio, making them ideal for supporting heavy loads over long spans. Angle sections, with their L-shaped profile, are often employed for bracing and framing, while channel sections are useful in situations requiring a balance of strength and light weight. Hollow sections are particularly favoured for columns and frames, offering excellent resistance to torsion and bending.

Steel sections are produced through hot-rolling, cold-forming, or fabrication processes. Hot-rolled steel sections are manufactured at high temperatures and are commonly used in structural applications due to their robustness and ductility. Cold-formed sections, on the other hand, are shaped at room temperature and are known for their precision and smooth finish, often used in lightweight structures or interior applications.

One of the key advantages of steel sections is their adaptability. Engineers can select specific sections based on load requirements, space constraints, and design preferences. Moreover, steel’s recyclability and long lifespan make it a sustainable choice in modern construction. It is resistant to pests, rot, and fire when treated appropriately, further enhancing its appeal in both residential and commercial building sectors.
