Roof over ice – SSAB’s structural hollow sections create a massive steel frame for ice skating arena in Norway

SSAB delivered over 700 tonnes of structural hollow sections to its customer Best-Hall for the steel frame to cover Atlanten Kunstisbane’s ice rink in Kristiansund, Norway. The building is 12,500 square meters in size, 187 meters long and 73 meters wide.
When ready ice arena will enable curling, ice-hockey, bandy, figure skating, speed-skating as well as fairs and events.
SSAB Domex Tube Double Grade (S355J2H/S420MH) was used in the project. It is especially designed for steel construction and meets or exceeds the requirements of standard EN 10219 and fulfills the specification of two steel grades: S355J2H and S420MH. The choice of grade depends on the customer's or designer's application and requirements. In this project, the steel structures were optimized so that the span length was made as wide as possible, which improved customer’s manufacturing process from the procurement of raw material onward. Hollow sections were produced at the SSAB Tube Mills in Finland. Most of the steel was delivered straight from rolling.
Best-Hall has production unit in Kälviä, Finland, where also the structures for Atlanten Kunstisbane were made. Installation of the arena started in September this year and construction will be finished in December.

New ice-skating arena for mild winter conditions
Atlanten Kunstis As was established in 2008, when winter conditions were good. Since then, however, the winters have been growing increasingly milder, with very high amounts of rain. This has resulted in even shorter winters. The idea of building a roof started to develop in 2012, when developer, Atlanten Kunstis AS, also first contacted Best-Hall.
Best Hall took up the challenge, projected a hall with rounded ends. After the tender process was launched in the fall of 2016 and comprehensive foundation work in spring 2017, we are now beginning to see and get an idea of the outlines of what will be a beautiful hall rising on the Atlantic Ocean in Kristiansund.
Best-Hall’s operations include the production and installation. Sawing, outfitting and surface treatment are all done in-house. C4M is required for the powder painting. “The consistent high quality of SSAB structural hollow sections is very important for us and enables efficiency in all our production stages,” said Leif Fagernäs, Managing Director of Best-Hall.
Altogether total of 60 trucks delivered the material from Finland to Norway. The construction site is very cramped. Huge sections required a 300-tonne crane and a 200-tonne crane. Installation took 4 months.
Long-term cooperation with Best-Hall
SSAB and Best-Hall have a long history of working together. Over the years, SSAB has held several technical training events for Best-Hall’s employees.
