In Europe, the main current reference in the manufacture of metal structures for civil engineering works is the Regulation 305/2011 (CPR).

For the purposes of the Regulation, "construction product" means any product manufactured in order to be permanently incorporated in construction works, including both buildings and civil engineering.

According to CPR a construction product fits for its intended use (and therefore it is possible the CE mark) if its characteristics are such as to allow the work to which it is intended, the fulfillment of the basic requirements applicable to it.

As a "construction product" it includes any structural metalcomponent, resulting from processing such as cutting, forming, welding, drilling, etc. A product is considered suitable for the intended use if it is demonstrated that it meets the basic requirements of the CPR through compliance with the relevant "harmonized technical specification".

For metal structural components, as defined above, the harmonized standard is EN 1090-1.

In order to CE Mark metal structural components in accordance with EN 1090-1, the Manufacturer must obtain the certification, by a Notified Body, of its Factory Production Control (FPC).

IIS CERT is Notified Body (number 0475) for the certification of Factory Production Control (FPC) according to EN 1090-1.
