Steel and aluminum used in construction must comply to specific European legal requirements by July 1,2014. Buildings , bridges , towers , masts , silos, landing flooring , siding and all types of beams should comply the specific requirements of the standard NEN – EN 1090.
Only when steel and aluminum construction and structural components meet the requirements of the EN 1090 it is allowed for the manufacturer to apply the CE mark on his product. Whit this mark the product is allowed to enter 28 countries of the European Union.
The NEN – EN 1090 consists of the following three parts :
– The NEN-EN 1090-1 covers the performance characteristics for structural steel and aluminum parts and kits that are marketed as building products. The focus areas are manufacturing characteristics and structural design;
– The NEN-EN 1090-2 describes the requirements for the implementation of structural steelwork , such as constructions or manufactured parts;
– The NEN EN 1090-3 specifies requirements for the implementation of aluminum structural components and constructions .
In order to get the CE-certification, the manufacturer must take into account all specific requirements in the following classification , EXC1 (for agricultural buildings and warehouses) , EXC2 (for buildings) , EXC3 (for road bridges) and EXC4 (for nuclear power plants and other extreme constructions).Then the manufacturer must set up a factory production control system (FPC) and let this get certified and only work with both certified welders and with a responsible welding coordinator .The CE certification of construction steel or aluminum will be completed by the producer with generation of a Performance Statement and affixing the CE-marking on the product .
