Portable A4

The Portable A4 System consists of 22mm solid hardwood floor boards, preassembled into light weight, hand carried panels. Each floor panel has several prefixed battens mounted with soft rubber pads to provide correct shock absorption and resilience.

Each floor panel is easily locked securely into position with a pre-mounted assembling fitting. Lengthwise the panels have a tongue and groove connection and at ends the panels are joined using loose tongues.

A supporting and protecting edge reducer forms a strong edge for the perimeter of the floor.

For faster and more flexible installation ask for Junckers CenterRow Panels that makes two way installation possible.

Junckers custom designed storage carts make transportation and storage of the panels easy.

Scandinavium Arena, Gothenbrug Sweden

As one of the busiest, largest indoor arenas in Scandinavia, Gothenburg Scandinavium Arena often needs to change their flooring surfaces to cater for the next activity, ranging from ice hockey to rock concerts. For handball matches, Junckers’ A4 Portable Sports Floor is installed on top of the ice and in a matter of hours, the arena boasts a floor with the same qualities as a permanent sports flooring system.
