    EXC3 class projects

    Our expertise is requested when, for example, a new sports center is being built. The structural foundation of the building requires the durability and quality that execution class EXC3 provides.

    We have delivered, among other projects, the steel framework for the sports center in Nokia. Our next sports-related project is the ice hall which is to be built in Tampere, for which we will produce and install the steel framework. Both projects require exceptional quality control in accordance to EN 1090 certificate, as well as the high-level technical knowledge associated with execution class EXC3.

    Knowledgeable, educated staff

    Long spans and heavy construction demand excellent planning and execution of projects, which is why we have hired the best engineers, welders, and other staff we could find.

    Our welding coordinators know how structure the work flow according to execution class EXC3. Both of our coordinators are IWS certified, while most of our welders have received IW schooling. Thus, the planning and production of our steel constructions is in very capable hands.

    EN 1090 certificate

    Our steel constructions meet the demands of the European standard EN 1090, which concern both the manufacturing process as well as technical properties of our constructions.

    The certificate enables us to mark our products with a CE marking. The CE marking is a guarantee that we have adhered to the standard throughout the entire manufacturing process.

    We want to supply our customers with the best possible end product. When working with other parties, we always make sure that the subcontractor adheres to the EN 1090 standards, as well as our own systems for quality control.
