ATLANT® Composite Columns

More architectural flexibility with ATLANT® Composite Columns

The ATLANT® composite columns enable construction flexibility, architectural freedom, and wide open spaces. By using the slender composite columns from ATLANT®, buildings can be designed and constructed to provide more usable space, better light and greater visibility within the building and to the outside.

ATLANT® Composite Columns are made from a hollow steel section with a shop installed reinforcement cage placed inside and columns are later filled with concrete on site. Standard HSS Profiles are available in square, rectangular, and round sections.

ATLANT® composite columns benefits:

  • More slender than other same resistance columns.

  • Strong columns capable of maintaining constant outer cross-section dimensions throughout floors.

  • Integrated fire proofing (of up to two hours).

  • Quick and easy installation.

  • No curing time required to load columns.
  • Architectural flexibility and more open interior space.

  • Compatible with beam systems for precast, cast-in-place, timber, hybrid, and other common slabs.

  • Optimal design and support provided by Peikko engineers.

  • Certified production in state-of-the-art factories.


Exceptional slenderness, high strength and built in fire proofing makes the ATLANT® columns an optimal solution for many applications. It can be single and multi- story columns used in both interior and exterior areas of various buildings.

ATLANT® composite columns provide architectural flexibility, cost effectiveness, construction simplicity, and speed.

Single-story columns

  • Used with continuous beams for longer spans or shallower profiles.
  • May reduce the beam price by up to 20% compared to single span beams due to the benefits of using the negative moment at the connection.
  • Usually filled from the top.
