MagFly® AP

Magnet for fast and precise shuttering of precast concrete elements - MagFly® AP

The MagFly® AP is a patented shuttering magnet and a component of the BT shuttering formwork system. Unique features include the magnetic force-to-weight ratio, plus the unique foot/spring system, which allows the magnet to slide easily over the formwork table.

The magnet is activated by a firm pressure from above and adheres to the formwork table by its magnetic force. The MagFly® AP can be detached and realigned simply and quickly using the integrated lever. It does not require any additional tools or adapters.

The ultra-light aluminium casing makes ergonomic work with the magnets possible and saves effort by the user. In combination with the MultiForm formwork girders and an additional plastic chamfer profile, the formwork girder and chamfer profile are pressed firmly to the formwork table when the magnets are activated. An additional sealing for the edge is not neccessary. These effective technologies are matched perfectly to each other and substantially speed up the production of precast concrete elements. You can view the application of MagFly® AP in our product video.


  • Best magnetic force to weight ratio of its class worldwide (22KN / 11 pounds)
  • Improved handling: release force now only 37 pounds.!
  • Integrated MagFly® technology for precise positioning
  • Precise fixation of the magnet by easy hand pressure
  • The permanently mounted eccentric lever makes additional tools for deactivation unnecessary
  • Fast return of investment
  • Patented shuttering fastening provides increased retention pressure for shuttering at the formwork table
  • No silicone sealant required
  • Light and ergonomic handling thanks to the foot/spring system
  • Magnet and formwork girder perfectly matched
  • Unbeatable adhesive force-to-weight ratio



  • Shuttering magnets for pallet circulation systems and tilting tables
  • Shuttering for walls, beams, etc.

The MagFly® AP has an adhesive force of 22,000 N with a weight of merely 5,6 kg. Therefore, it has a first-class adhesive force-to-weight ratio. For more powerful magnets, you can fall back on the MagFly® universal magnet, which is available with an adhesive force of 30,000 N.   

The MagFly® AP is equipped with a patented foot and spring system. This creates a gap between steel surface and magnet, so the magnet can flexibly be moved across the steel table before activation. Only with some light pressure from the top will the gap be closed, the magnet activated, and the adhesive forces go into action.  

The MagFly® AP can be combined with the MultiForm and MultiForm Alu. The formwork girder allows for the insertion of magnets with special pockets. Afterwards, the shuttering can be moved flexibly on the formwork table and will only be securely fixed with the activation of the magnets. Should a shuttering not be positioned correctly, it can easily be re-adjusted, because the magnets can simply be deactivated with the integrated lever simply and quickly. More information on formwork girders can be found here: MultiForm / MultiForm Alu.


The MagFly® AP itself allows for few possibilities to combine it with various extensions for the production of custom solutions. However, for this BT developed the MagFly® universal magnet, which can be combined with a multitude of extensions, in order to cater to every customer’s use cases. More information on the universal magnet can be found here: MagFly® universal magnet.

Do you have questions?

1. What should be considered when using magnets?

The general safety instructions for handling industrial magnets apply. More detailed information can be found in the user manual of the MagFly® AP.

2. How is the magnet cleaned?

The magnetic clamps should always be kept clean. Ideally, the magnets should be cleaned after each use and potential concrete residue or other impurities should be removed, especially from the bottom (holding surface). Mechanical cleaning with a wire brush is advised. More detailed information can be found in the user manual of the MagFly® AP.

3. What do I do if I need a replacement part?

Replacement parts for self-assembly can always be delivered. Please ask your BT contact person for the list of replacement parts for the MagFly® AP. For the repair, we will gladly provide you with detailed repair instructions and videos.

4. How can I store magnets that I am not currently using?

For the storage of the MagFly® AP, we developed a shelf system. This allows for the space-saving storage of magnets between production cycles and also ensures higher work safety. Additionally, it is possible to also clean the magnets there. The racks for magnets can be moved by crane or cart through the production, so that time-consuming individual transport is not necessary.

5. How can I reduce strain on the magnet?

The strain on the magnet can be significantly reduced by the protection cover, specifically developed by BT. Cleaning measures to remove concrete residue or repair measures can be reduced. The protection cover is simply mounted on the MultiForm before concreting and thereby protects the magnet from residue during production.
