Construction company Best-Hall has used over 700 tonnes of steel structural hollow sections, produced by SSAB, to build the frame covering the Atlanten Kunstisbanes ice rink in Kristiansund, Norway.
The need for a roof to be built to cover the ice rink, which opened 2008, came about in 2012 due to Norwegian winters becoming increasingly mild, with very high amounts of rain.
The steel structures, which make up the 187 metre long and 73 metre wide building, were optimized so that the span length was made as wide as possible, which improved the manufacturing process from the procurement of raw material onward. Hollow steel sections were produced at SSAB tube mills in Finland with most of the steel delivered straight from rolling.
SSAB Domex Tube Double Grade was used in the project and it is specially designed for steel construction projects, meeting or exceeding the requirements of standard EN 10219 and fulfilling the specifications of two steel grades: S355J2H and S420MH.
A total of 60 trucks delivered the material from Finland to Norway, where a 300-tonne crane and a 200-tonne crane were used to put them in place.
