For BS Steels and our clients, there are two main aspects of EU legislation on CE marking:
BS Steels has achieved Execution Class EXC3, under the CE legislation. This is the level required for our business in the highways, railways and major structures areas, where higher performance is required to accommodate higher structural risks.
Accreditation for execution class EXC3 enables us to take on contracts requiring EXC1 and EXC2 (the category for most UK building projects).
Leading testing company Ultramag is working with BS Steels on an ongoing basis, providing in-house training and testing, as well as site weld testing.
CE marking of construction products was introduced back in the late-80’s, and enforced by the Construction Products Regulations 1991.
EU Legislation has been in place since 1st July 2013. All steel and products purchased by BS Steels is CE marked. This is the manufacturer’s responsibility.
However, in most cases, these products are not simply sold on by us in their original form or packaging. We therefore ensure that we provide documentation to provide traceability of the steel and products that we provide.
All our contracts and documentation take account of necessary standards covering materials, information, welding, bolting, fabrication, erection, protective treatments and quality control.
If you would like further information on CE marking, and BS Steels’s compliance, please contact Nicola Williams or Roger Slade.
Below is a simplified explanation of CE marking as applied to steelwork fabricators such as BS Steels. It should not be relied upon as a comprehensive guide, but is provided as a framework to establish BS Steels’s procedures and compliance.
For all fabricated structural steelwork delivered to site from 1 July 2014, there is a legal requirement under the Construction Products Regulation (EU) No 305/2011 of the European Parliament and of the Council of 9 March 2011 (‘CPR’) that it is CE Marked.
This places certain obligations on the client and the contractor:
From these documents, the following can be established:
Definition of Consequence Classes: in other words, how significant could be the consequences of the building or structure failing? A tall, multi-occupied building or stadium would clearly have a higher consequence than say an agricultural storage unit.
Definition of Service Category: considers the risk from actions to which the structure and its components may experience during erection and use. The stress levels in components in relation to their resistance are also taken into account. Most static buildings will be in the lower category, whilst the effects of vibrations from, for example, wind and crowds, would put structures such as road and railway bridges and stadia in the higher category.
Definition of Production Category: considers the risk from the complexity of the fabrication of the structure and its components (which may have a different category than the overall structure). The eventual Execution Class is not, in fact, sensitive to the Production Category selected.
Derive the Execution Class: using a matrix derived from BS EN 1090-2, of the Consequence Class and Service Category, the relevant Execution Class can be established, ranging from EXC1 (the least demanding class) to EXC4 (the most demanding, including special structures or structures with extreme consequences of a structural failure). For the majority of buildings constructed in the UK, EXC2 is the appropriate requirement. Note also that the relevant Annex of BS EN 1090-2 is classed as ‘informative’ rather than mandatory, meaning that the engineer has some discretion to base the selection of Execution Class on experience, provided they can support their decision.
Steelwork contractors must declare performance to the System 2+ level of assessment (as described in Annex V of the CPR). This requires them to undertake:
They must also be assessed by a notified body that will carry out:
The notified body will then issue a FPC certificate and Welding Certificate identifying the Execution Class that the steelwork contractor has achieved.
