CE marking for steel structures and components has become mandatory in the UK, under the Construction Products Regulation (CPR). It is now a criminal offence to supply a steel structure or steel components without a CE mark.
To apply the CE mark, manufacturers, contractors and fabricators will need to demonstrate compliance with BS EN 1090-1 Part 1: Execution of steel structures and aluminium structures and part 2 (for steel structures) or part 3 (for aluminium structures).
BS EN 1090-1: Requirements for conformity assessment of structural components explains that, since all structural steel is seen as safety critical, manufacturers must document and implement a Factory Production Control (FPC) system and have the system certified by a Notified Body.
BS EN 1090-2: Technical requirements for steel structures, outlines what is required to ensure steel structures meet adequate levels of mechanical resistance, stability, serviceability and durability.
BS EN 1090-3: Technical requirements for aluminium structures, outlines what is required to ensure aluminium structures meet adequate levels of mechanical resistance, stability, serviceability and durability.
The standard sets out four Execution Classes (EXCs):EXC1 – e.g. Agricultural buildings
EXC2 – e.g. Residential or Commercial structures
EXC3 – e.g Bridges
EXC4 – e.g.Special structures (long-span bridges etc)
For EXC 2,3 & 4, all welding must be controlled by a Responsible Welding Coordinator (RWC), with proven competence, in accordance with the requirements of EN 14731 and the relevant part of EN ISO 3834. Manufacturers must supply a certificate that specifically states that the RWC is trained to these standards as proof of compliance.
For Structural Steelwork Contractors to demonstrate their CE Marking capability the Construction Product Regulations (CPR) require the folloiwng 3 key documents:-
We have used Guthrie and Craig for both management services and traditional training. Without exception they have provided professional and knowledgeable staff who have worked on site and remotely to deliver exactly what was required on time and on budget. We are impressed with the service and flexibility shown by G&C to meet our needs despite changing requirements and operational timescale.
