Cap Beams

Cap Beams

Cap beams are a variant of top-hat beams

Cap beams (also called THQa beams) are a variant of the top-hat beams. The construction consists of four parts: two vertical body plates are mounted on a wide bottom plate that projects to one side. A thicker top plate is welded between these body plates.
Cap beams are mainly used when installing prefabricated floor panels at the edge of a building structure.

Composite Steel Beams

  • Suitable for prefabricated floor elements
  • Application at the edge of structures
  • Absorbs horizontal forces

Top-hat beams absorb horizontal forces

As with top-hat beams, an additional feature of the cap beam is that it absorbs horizontal forces in a steel skeleton well when subjected to wind loads.
If there is good cohesion between the hollow-core slabs, the entire floor acts as a disc and the forces can be dissipated in wind bracing.

The main advantages of cap beams are:

  • Low building height
  • More pipe space thanks to low floor height
  • Versatile and lightweight application in many suspension structures
  • Low design costs
  • Quick and easy installation
  • Easy fire-resistant preservation

All cap beams produced by Composite Steel Beams are made from S355 structural steel (normalized rolling). This type of steel has a higher strength, but is not more expensive than other types.
