TRIO Panel Formwork

TRIO is a universal formwork system which places the highest emphasis on uncomplicated forming operations and the reduction of shuttering times.
Few different components and, in particular, the universal BFD alignment coupler which can be operated with one hand, ensure quick and easy forming operations with TRIO.
Equipped with platform systems, TRIO provides maximum safety for the construction team. Complete largearea moveable units with working platforms, access ladders and guardrails are moved from cycle to cycle.
The TRIO shaft element for quickly moving complete sets of shaft internal formwork: by pulling the shaft corners, this results in a striking clearance of 30 mm, and the unit can be moved in one crane lift.
The aluminium TRIO panel elements are yellow powder-coated; they can easily be moved by hand.
Wall heights up to 3.30 m can be formed with TRIO 330 without any height extensions and with only two tie positions. The 3.30 m high panel can also be combined with the 2.70 m version.
The BFD Coupler can be operated with one hand. The framed panels are connected flush, aligned and tight in one working step.


TRIO is the universal formwork system for all applications where the main focus is on reducing the shuttering times with conventional DW tie technology. With the BFD coupler for virtually all connections as well as many other practical system solutions, TRIO has successfully proven itself in countless projects around the world. TRIO can be used together with the more advanced MAXIMO panel formwork. A large range of accessories, such as the BFD Coupler or MXK Bracket System, can be used in both systems.

Easy and simple connections
with the BFD Alignment Coupler as the only component for all panel connections

Fast working operations
with only a minimum of panel widths as well as panels that can be used both horizontally and vertically

Large-area shuttering
with standard panels up to 3.30 m x 2.40 m – providing a high level of surface evenness and only 2 tie positions

Technical Details

  • Flexibly used panel formwork for fast working operations, compatible with MAXIMO panel formwork
  • Panel heights up to 3.30 m, panel widths up to 2.40 m (standard system)
  • Maximum permissible fresh concrete pressure: 80 kN/m²
  • Can be used with DW 15 and DW 20 tie systems
  • Flush, aligned and tight connections with the BFD Alignment Coupler – including filler timber compensations up to 10 cm
  • Simple cleaning operations due to the powder-coated frame

Extended programme

TRIO Aluminium

Lightweight formwork for crane-independent working; easily distinguishable by its yellow powder coating

TRIO Structure

TRIO panels with a free choice of formlining for special concrete surface requirements – supplied already pre-assembled

TRIO Housing

  • Conically-shaped ties installed from one side on the ground
  • Element with securely mounted working platforms and push-pull props
  • Formlining screwed on at the rear

TRIO shaft element

With the TRIO shaft element, complete shaft internal formwork can be moved quickly; the all-round striking clearance is 30 mm.

MXK Bracket System

The MXK Bracket System serves as a working platform on MAXIMO and TRIO. The modular design and lightweight, manually-assembled system components ensure fast installation and a high level of costeffectiveness. In contrast to conventional solutions, the modular system provides pre-assembled individual components, e.g. the MXK Scaffold Deck or PROKIT PMB Side Mesh Barrier.
