As of July 1st 2014 any series manufactured structural metal components or kits that have been either made in the UK or imported, and to which a harmonised European standard applies, must comply with the CPR & CE marking requirements. The harmonised European standard that applies to structural metalwork is BS EN 1090-1 and it will be a criminal offence to supply structural metalwork after the 1st of July 2014 unless it conforms to this standard and carries a legitimate CE mark.
