Invisible Connections has launched a brand-new ‘’game changing’’ stair and landing connector.
RVK and TSS 60 P are a sustainable connectors for prefabricated concrete stair and landings. We have reduced the amount of steel by more than 50% and the outer tube is made from recycled PE from the local company Plasto AS.
With our new connections you can also lower the landing/stair slab thickness, full capacity 60 kN 170 mm, but can be used all the way down to 120 mm.
Thinner slabs -> less concrete -> lower CO2 emissions.

We wish all our customers, suppliers and other connections a pleasent easter holliday.

Invisible Connections will inform everyone that we will keep the factory closed from Friday 26. Mars until Tuesaday 6. April.

Another milestone for Invisible Connections AS. The first pallet RVK 60 P is finished today. RVK 60 P is a sustainable landing attachment for concrete stairs. We have reduced the amount of steel by more than 50% and the outer pipe is made of recycled PE. The material comes from recycled household plastic. RVK 60 P in use together with our TSS 25 stair connector, gives manufacturers the opportunity to reduce the amount of concrete in landings by more than 20%. Invisible Connections AS aims to contribute to a more sustainable future.
