- fulfils any architectural requirement, as there are no restrictions on the choice of form-facing and tie-hole pattern
- permits any pouring rate, as it can easily be dimensioned for any fresh-concrete pressure
- cuts equipment costs by allowing high numbers of repeat uses
- cuts labour costs by facilitating short forming-times
- minimises the craneage requirements because of its large, optimised shifting units<
- perfect joint pattern thanks to the exact element joints
- time and space savings at the site
- no finishing-work needed, as the elements fit exactly
- special solutions for bridge, tunnel and industrial construction
- safe vertical access with the Ladder system XS
- workplace safety on all sides with the Platform system Xsafe plus
- practical accessories – such as panel struts, lifting/repositioning devices etc. – make for safe, easy handling of the formwork

System
Top 50 in detail
The Doka formwork beams H20 (1) and the steel walings (2) are spaced closer together or further apart, depending upon what loads are expected. The form-facing (3) is freely selectable, to meet widely differing requirements.
Formwork built by Pre-assembly
The individual parts of the Top 50 system can quickly be assembled into site-ready elements by means of easy-to-use connecting devices: this saves on assembly costs. Having the elements pre-assembled ensures top-quality, meaning precision element joints and a first-class joint pattern, even with challenging geometries. For high numbers of repeat uses, fielding Large-area formwork Top 50 pays off even more.
Free choice of form facing and form-tie pattern
With the Top 50 system, key architectural specifications can be fulfilled.
Utilisation
Fair-faced concrete
Because it can be used with any form facing and adapts to any shape of structure, Large-area formwork Top 50 is particularly suitable for forming concrete that has to meet stringent specifications regarding its surface finish (i.e. fair-faced concrete).
