The NEN-EN 1090
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.

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 .
