MIDI panel system

MIDI panels are modular elements which are completed with a range of steel accessories for assembling.

They represent the advantageous ALPI system for working on site with tight schedules and best results and, thanks to their size and modularity, are the most used system in residential building.

The MIDI element consists of a 10 cm thick steel frame, to which a 15 mm multiply panel (100% birch) with phenolic coating on both surfaces is applied.

The panels are connected by clamps which assure coplanarity, perfectly tighten and align the panels together by simple hammer blow.

MIDI panels are compatible with most ALPI products and, if required, can be regenerated by replacing the plywood.


  • Accessories are reduced to a minimum, in order not to complicate work on site with an excessive quantity of different elements.
  • The formwork can be mounted in both vertical and longitudinal direction, to create large units which can be handled easily with one crane lift.
  • Designed to satisfy all size requirements, the range of available widths goes from 25 to 200 cm.
  • The permissible pressure is 50 kN/m2 in condition of constant pressure or 75 kN/m2 for walls with height of 3 m. (The technical manual indicates the permissible concreting pressures.)
  • The range of MIDI panels and accessories is available for sale and rental.
