Formwork beams

Formwork beams are load-bearing primary and secondary beams used in slab and wall formwork. They transfer the loads from concrete, formwork facing and workers onto props, headtrees or shoring towers and form the structural basis of a safe formwork assembly. Formwork beams are therefore a central component for load transfer, alignment and structural stability in every concreting phase.

Advantages of formwork beams in shell construction

1. High load capacity and safe load transfer

Formwork beams distribute concrete and dead loads reliably. This means more safety when concreting slabs and allows precise formwork surfaces.

2. Flexible use

Beams suit classic slab formwork, downstand beams, beam drops or special areas and can be combined in many ways, ideal for contractors who must respond flexibly to project requirements.

High-quality formwork beams are robust and reusable and are therefore a key economic factor on shell construction projects with high cycle rates.

Typical areas of use

During the concreting phase, formwork beams perform central tasks:

• Load transfer of concrete, formwork facing and dead weight
• Distribution of loads onto construction props, headtrees or shoring towers
• Alignment of the formwork facing for even concrete surfaces
• Formation of modular load-bearing systems in slab, wall and prop combinations
• Use as
  • primary beam
  • secondary beam
  • transition base
  • substructure for special solutions

They therefore combine structural safety, dimensional accuracy and working speed on site.

Formwork beams overview

Timber and composite beams

Classic H-beams with high stability for slab and wall formwork.

• high all-round benefit

X more sensitive to moisture

Steel formwork beams

Very robust beams for demanding or permanent applications.

• very robust and long-lasting

X heavier to handle

Lightweight formwork beams

For projects with frequent repositioning or tight handling.

• easy to move

X less robust than steel versions

System formwork beams

Beams belonging to specific formwork systems (wall and slab).

• fast assembly within the system grid

X system-dependent

Bearing and transition beams

Shorter beams for detail points, transitions or special areas.

• ideal for detail zones

X limited load share

FAQ: formwork beams

What are formwork beams used for?

To carry and distribute loads in slab and wall formwork.

Are formwork beams reusable?

Yes, depending on material and use they are long-lasting components.

Can different beam types be combined?

Yes, provided it is structurally permissible and system-compliant.

What is the difference between timber and steel beams?

Timber is flexible and lighter, steel is more robust and longer-lasting.

No, they belong to specific formwork systems.

How important are the accessories?

Accessories create safe connections and load points.
