Aluminium formwork beams

Low weight, high load capacity and long durability

the strong arguments for aluminium formwork beams. Special design – with or without integrated nailing strip and integrated fixing slot – and high load-bearing capacity combined with low weight and high durability open up many new possibilities for the construction site.

Alu box beam

The lightweight, heavy-duty load-capacity aluminium beam for materials-optimised jobsite use

  • high load capacity achieved by innovative beam cross-section
  • cost-cutting by reducing the number of items needed
  • long life span thanks to high manufacturing quality

Doka aluminium beam 20

Combine resistance with lightness and optimise your loadbearing towers with the Doka aluminium beam 20

  • Excellent cost-efficiency because of long lifespan
  • Easy to handle due to aluminium lightweight construction
  • High workplace safety thanks to high load capacity and compatibility to Doka components and systems

Alu box beam

The lightweight, heavy-duty load-capacity aluminium beam for materials-optimised jobsite use

alu box beam

(A) built-in high-quality plastic railing strip
(B) end-to-end built-in fixing slot


Technical specifications:

Moment (M): 14.9 kNm
Shear force (Q): 23.2 kN
Rigidity (E x l): 729 kNm²
Weight: 7.3 kg/lin.m
Overall height: 17.5 cm


High load capacity

achieved by innovative beam cross-section

  • permitted bending moment M = 14.9 kNm
  • permitted shear force Q = 23.2 kN
  • rigidity E x I = 729 kNm²
  • weight = 7.3 kg/lin.m
  • overall height = 17.5 cm

Cost-cutting

by reducing the number of items needed

  • up to one-third fewer floor props for floors. as wider beamspans are possible
  • up to 50 percent fewer primary beams in the superstructures of fully loaded 10 kip shoring towers or Staxo 100 load-bearing towers. thanks to high load capacity
  • optimised site logistics and lower freight costs. as fewer items are needed

Long life span

thanks to high manufacturing quality

  • high numbers of repeat uses made possible by wear-resistant aluminium
  • the integral end-to-end fixing slot prevents damage to the beams
  • integrated. high-grade plastic nailing strip makes it easy to fix formwork sheets

Doka aluminium beam 20

Combine resistance with lightness and optimise your load-bearing towers with the Doka aluminium beam 20

alu 20 beam

(A) continuous, integrated mounting groove


Technical specifications:

Moment (M): 18.4 kNm
Shear force (Q): 50.0 kN
Rigidity (E x J): 849.9 kNm²
Weight: 6.4 kg/lin.m
Height: 20.0 cm


Excellent cost-efficiency

because of long lifespan

  • retains its robust mechanical properties over entire usable life due to resistance against dampness rain, UV light, etc.
  • reduced number of e.g. load-bearing towers thanks to highly stressable beam for maximum prop spacing
  • lower number of new purchases due to long lifespan

Easy to handle

due to aluminium lightweight construction

  • only 6.4 kg per linear metre due to use of aluminium
  • energy conserving and fast working thanks to low weight

High workplace safety

thanks to high load capacity and compatibility to Doka components and systems

  • high mechanical load capacity over entire usable life due to resistance against weather conditions
  • increased work safety thanks to compatibility with Doka safety systems, e.g. Edge protection system XP
