Structural steel comes in various shapes, each serving specific purposes. Some common shapes include I-beams (also known as H-beams), channels, angles, and hollow sections. These shapes provide strength and stability in different directions.

Structural steel and reinforced concrete are both used in construction, but they have distinct characteristics. Steel offers high strength-to-weight ratio, flexibility, and ease of fabrication. Reinforced concrete, on the other hand, combines concrete’s compressive strength with steel reinforcement for added tensile strength.

In high-rise buildings, structural steel provides the framework that supports the entire structure. It allows architects to create open spaces, large spans, and flexible layouts. Steel’s fire resistance and ability to withstand seismic forces make it an excellent choice for tall buildings.

Structural steel fabrication involves cutting, bending, welding, and assembling steel components. Fabricators follow detailed shop drawings to create beams, columns, and other elements. On-site assembly involves connecting these components using bolts or welding.

Structural steel offers several advantages, including:

• • High strength and load-bearing capacity.
  • Durability and resistance to corrosion.
  • Speed of construction due to prefabrication.
  • Recyclability and sustainability.
  • Design flexibility for creative architectural solutions.

1. Properties of Hot-Rolled Steel:
   • Rounded edges and corners due to the rolling process.
   • Minimal surface imperfections (waviness) that don’t compromise structural integrity.
   • Rougher surface texture compared to cold-rolled steel.
   • High malleability, allowing easy shaping.
   • Enhanced ductility and toughness for bending and shaping operations.
2. Advantages of Hot-Rolled Steel:
   • Enhanced performance (higher strength and durability).
