Steel sections are categorized based on their shape, size, and application. Here are the main types:
1. I-Beams
Shape: I-shaped cross-section.
Applications: Structural frameworks, bridges, and buildings.
Properties: High strength-to-weight ratio, good for bending and shear loads.
2. H-Beams
Shape: H-shaped cross-section with wider flanges.
Applications: Heavy construction, columns, and beams.
Properties: Greater load-bearing capacity than I-beams.
3. Channels
Shape: C-shaped cross-section.
Applications: Framing, supports, and lightweight structures.
Properties: Good for secondary structural elements.
4. Angles (L-Sections)
Shape: L-shaped cross-section.
Applications: Brackets, frames, and reinforcements.
Properties: Versatile, used for both structural and non-structural purposes.
5. T-Sections
Shape**: T-shaped cross-section.
Applications**: Trusses, bridges, and machinery.
Properties**: Used where a flat surface is needed on one side.
6. Z-Sections
Shape: Z-shaped cross-section.
Applications: Purlins and wall supports.
Properties: Efficient for spanning long distances.
7. Tubular Sections
Shape: Circular, square, or rectangular hollow sections.
Applications: Structural frameworks, fencing, and machinery.
Properties: High torsional resistance, aesthetic appeal.
8. Flat Bars
Shape: Rectangular cross-section.
Applications: Framing, supports, and decorative elements.
Properties: Simple and versatile.
9. Round Bars
Shape: Circular cross-section.
Applications: Shafts, fasteners, and machinery parts.
Properties: Good for machining and fabrication.
<!--[if !supportLists]-->10. <!--[endif]-->Square Bars
Shape: Square cross-section.
Applications: Structural supports and decorative uses.
Properties: Uniform strength in all directions.
Summary
Steel sections are classified by their shape and application, each offering distinct properties suited for different structural and mechanical needs. Common types include I-beams, H-beams, channels, angles, tees, Z-sections, tubular sections, flat bars, round bars, square bars. The choice depends on load requirements, environmental conditions, and design specifications.
