Steel Structure

Frame Structure

Frame structures consist of rigidly connected steel beams and columns that form a moment-resisting framework. This system is especially effective for low-rise industrial buildings where large, open floor areas are needed without interior supports — such as in warehouses, workshops, and aircraft hangars. The shape resembles a doorway, which is how the term “portal” originated.

Key Advantages:

  • Simplified geometry allows for efficient load distribution under both vertical and lateral forces
  • Faster and more cost-effective to build compared to conventional concrete framing
  • Ideal for clear-span layouts with minimal interior obstructions

Typical Applications:

Industrial plants, storage buildings, agricultural facilities, and logistics warehouses.

Also, portal frames offer excellent seismic resistance due to their inherent rigidity and joint continuity.
