- We have delivered a unique suspension system that has never been made before. At the same time, we are proud to contribute to the new National Museum meeting important environmental requirements, by using up to 80 percent recycled steel, says Børre Lobekk, CEO of Nordic Steel.
The walls around the National Museum are covered with slate. The suspension system on which the slate is mounted are unique steel brackets, specially made from Nordic Steel. Nearly 1,600 different brackets were made for the National Museum, where the number of each type varies.
- Almost no brackets are alike, they have different lengths, dimensions and different fastening points. Some are fixed in the lower part of the building, others further up on the wall, which means that they have to withstand various loads, Lobekk explains.
Railings, benches and boxes for walling in technical equipment were also part of the complete delivery from Nordic Steel.
For contractor AF Gruppen, it was crucial to pick a reliable supplier for the project.
- Such a suspension system has not been made before, therefore it was extra important for AF Gruppen to use a reliable quality supplier. Nordic Steel has high precision on deliveries, understands the need and always delivers within the quality we need, says Hedda Kløvig, project engineer at AF Byggfornyelse during the construction of the National Museum.
Among other things, Nordic Steel gets contracts because the company delivers on strict environmental requirements in public procurement, offers climate accounts and environmental declarations. The construction of the National Museum had very high climate requirements for, among other things, greenhouse gas emissions and material choices. One of the climate measures was the use of recycled steel rather than new steel.
High quality and competence at all levels is necessary to carry out an assignment as at the National Museum. Statsbygg as the client had strict requirements for both implementation and quality of the project.
Nordic Steel delivers on the highest requirements for certification and approvals. Documentation on all projects is an important part of the delivery.
Approximately 350,000 kilos of acid-proof steel brackets for the National Museum were designed and produced at Jæren, before being sent to Oslo for assembly.
- We test our welds before we start. All welders have approved certificates for work in accordance with the welding procedures to be used, says William T. Boomer, welding coordinator at Nordic Steel.
An external welding inspector checked and approved all the welds for the project according to NS-EN ISO 5817: 2014, to double check and document that everything was correct. This was done, among other things, by measuring the size of the welding strings and the thickness of the weld.
