Products

A-BEAM®

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

Ties

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.

Brackets and supports

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.

Lifting systems

The AN lifting anchor is a product developed for lifting sandwich panels, enabling quick installation and protecting the panels against fractures.

Balcony connections

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

Bolts and shoes

Anchor bolts and column shoes can be used in concrete element frame connections to foundations and column extensions.

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, ADL 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.
