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.
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.
