The Best of Both Worlds: Steel and Concrete

DELTABEAM® Frame Consists of DELTABEAM® Composite Beams and Composite Columns

A DELTABEAM® is made from four steel plates welded together to allow for optimization of plate thickness. Reinforcement is also added inside the beam at the plant to achieve required fire resistance once filled with concrete.

DELTABEAM® Composite Beam benefits

  • Slim Floor: Uniform thickness starting at 8 inches.
  • Long spans over 35 feet.
  • Integrated fire resistance of up to 4 hours.

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.

Composite Column Benefits

  • Integrated fire resistance of up to 4 hours.
  • No curing time required to load the columns.

A Frame for All Building Types

  • Residential & Hotels
  • Commercial
  • Offices
  • Institutional
  • Healthcare
  • Parking Structures
  • Mixed Use

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.

Multi-story columns

  • No height restrictions when using custom built HSS sections.
  • Usually filled from the bottom.
  • Reduces the number of components (crane picks).
  • Used with single span beams

DELTABEAM® Frame Advantages

Slim Floor

Uniform thickness starting at 8 inches

Maximize the number of floors or reduce the overall height for all types of buildings.

Fast Construction

Erect a 10000 ft2 floor every 4 days

Only 5 erectors are needed to put up a floor every 4 days. This includes DELTABEAM® Frame hollow-core slabs and grouting. Minimal need for shoring posts and no curing time results in quick access to trades.

Fire Resistant

The 1st UL fire-rated exposed steel beam

1, 2, 3 and 4-hour fire ratings with no additional fire-proofing required.

Long Spans

Superior flexibility

The composite design allows for maximum flexibility of the interior layout and a reduction in foundation costs.


Reduced cladding area

Allows for energy savings by reducing the overall cladding surface.

DELTABEAM® Frame is made from recycled content.

Trade Friendly

Simplified HVAC and MEP installations

Eliminates conflicts with mechanical systems.
