What is EN 1090-1 and CE marking for structural metalwork?

EU & UK Law In 2012 The Construction Products Regulations (CPR) was introduced, this places a requirement on construction products that have a harmonised standard to be CE Marked. EN1090 is the harmonised standard for structural steel however the implementation of EN1090 has been delayed until 1st July 2014. As of the 1st July 2014 it will be a criminal offence to supply structural metalwork unless it conforms to this standard and carries a legitimate CE mark.

The European Construction Products Directive. Is aimed at harmonising the safety performance of construction products across the EU and they apply to anything placed on the market, whether imported or manufactured in the EU.  The CPD defines six principles for materials that are to be used in civil engineering including:

1.   Mechanical resistance & stability           (ITT / initial type testing)

2.   Safety in case of fire                                 (Fire testing)

3.   Hygiene, health & the environment        (design)

4.   Safety in use                                               (clear usage instructions & risk assessment )

5.   Protection against noise                          (risk assessment)

6.   Energy economy & heat retention          (environmental performance)

New legislation was introduced in 2013 to allow the CPR to be enforced by the Trading Standards authority, which will have the power to stop a business from trading and to withdraw any products supplied after July 1st 2014.  In severe cases Directors may also be imprisoned.

Who needs to comply?

The regulations apply to a wide range of activities involving “series” manufactured items:

§  Manufacturers of metal components or kits that have a structural use in civil engineering.

§  Importers of structural metalwork kits or components

§ Stockholders and metal processors that modify stock - for example by drilling, painting, bending, electroplating 

The term “series” means mass produced or more than one for example multiple production such as staircases but not necessarily an access platform as a one off (non series) production, however the controls required are same and many larger organisations purchasing structural/fabricated steel may insist on CE Marking to ensure they have net their legal duty of care.

What do I need to do to comply?

There are 3 “consequence classes” it is anticipated that the majority of structural steel fabricators in the UK will fall within consequence class 2.

Consequence class 1 (CC 1)


Low possibility of loss of human life, or economic impact, social or environmental consequence – minimal to negligible loss

Agricultural buildings where people do not normally enter, low use, storage areas, greenhouses, etc.

Consequence class 2 (CC 2)


Medium possibility of loss of human life, or economic impact, social or environmental consequence – considerable loss

Residential and or office buildings with regular use, although not highly populated

Consequence class 3 (CC 3)


High possibility of loss of human life, or economic impact, social or environmental consequence –

very great and serious impact

Stadium, concert hall, public buildings, etc. human activity very high usage most days of the year


You need to have what is known as an FPC (factory Production Control system) this is set of procedures and documentation that ensure the following amongst other requirements:

§  Traceability of materials (to original mill certs and test results)

§  Competence of welders/fabricators (coded welders/weld testing)

§  A responsible welding coordinator needs to be appointed

§  Drawings and calculations to prove the structural integrity of materials/fabricated items

§  Calibration of equipment (welding equipment)

§  Control of defective materials and products with corrective action process (fixing errors)

§  Purchasing procedures and approval for materials and subcontractors

§  Quality control systems to ensure the quality of manufactured products

Holding certification to ISO9001 will provide the majority of evidence required for EN1090 but you will need some additional controls as detailed above. When all this is in place you need to have a third party audit/inspection by a notified body which is UKAS accredited.


How can we help?


We have a team of consultants who are also 3rd party auditors recommending certification to EN1090 so fully understand the certification process inside out.


We have developed standard documentation and procedures that ensure compliance to the requirements of both ISO9001 and EN1090


§  Initial gap analysis

§  Provide all necessary documentation including procedures forms etc..

§  Generate an action plan

§  Develop any additional controls and documentation 

§  Liaise with a UKAS accredited certification body to arrange certification

§  On-going support to maintain certification (where requested)


Where companies meet certain criteria, we may also be able to access financial support to implement your system.


We can also help with other standards such as ISO14001:2015, OHSAS18001, ISO27001 etc…
