Column shoes

APK®-CM beam shoe

APK®-CM beam shoes are used in moment-stiff beam-to-column connections of industrial concrete element frames. The beam shoes are also suitable for heavy-duty concrete element frame connections in office, commercial and public buildings. The APK®-CM beam shoe is manufactured in accordance with SFS-EN 1090-2:2018 and is designed according to the requirements of the European standards.

The connection consists of a prefabricated beam shoe that is installed in the beam’s element formwork before casting. The column element has an anchoring bolt corresponding to the shoe as well as rebar coupler connection pieces. The connection can also be used to form continuous moment-stiff beam frame structures in the concrete element frame. The beam shoe anchoring bolts are ALP®-P2S and ALP®-P2SM.

Beam shoe connection design is made easy and fast with ACOLUMN® design software.

A-BEAM® and Anstar’s connection technology form part of the frame system, offering cost-efficiency and flexibility for construction.


Diagonal ties are used in concrete sandwich panels to connect the outer skin with the inner skin through the insulation layer. The ties transfer the self-weight and wind loads of the outer skin to the inner skin.

Fastening plates

Fastening plates are used on cast-in-place and prefabricated structures to provide a mounting surface for welding.

Suspension components

Anstar has developed bracket and support systems for efficient and affordable construction. The connection pieces are easy to install both at the prefabrication factory and on site.

Balcony connections

Balcony hinges are used to transfer horizontal forces from the balcony to the building frame. The hinged connection enables vertical movement.

Rebar bolts and anchor bolts

high-quality rebar and anchor bolts are responsibly made with recycled steel. There are two different basic types of bolts: ATP- ja AHP® rebar bolts and ALP® anchor bolts

AEP® hidden bracket

AEP® hidden brackets are used to fasten a concrete element beam or Anstar A-BEAM® to the side of a concrete element column, wall or another beam. 

AOK® support

The AOK® support is used in a hollow-core slab floor opening as the load-bearing structure for the end of the slab. The AOK® support has been granted a patent, which enables exclusive rights to the most cost-effective support in the market.

Column shoes

Column shoes are used in light- and heavy-duty column extension and foundation connections; wall shoes are used in the tension connections of stiffening wall and shaft elements, retaining walls and earth pressure walls that stiffen the building.

Rebar couplers

Rebar couplers are used for joining rebars with full tension capacity. The ends of bars to be joined are provided with threads, and the bars are joined using a coupler sleeve that transfers the force on the rebar across the connection.

Bracing connections

ADE® and ADK® bracing connections are designed for stabilising the concrete element frame. These connections
are used in the joints between concrete columns and stabilising steel bracings.
