PN-EN 1090-1+A1:2012 Requirements for steel structures

Requirements for Steel Structures

The EN 1090 "Execution of Steel and Aluminum Structures" standard is a set of requirements for steel and aluminum structure contractors. It consists of three parts:

• EN 1090-1: "Principles for the assessment of conformity of structural components"
• EN 1090-2: "Technical requirements for steel structures"
• EN 1090-3: "Technical requirements for the execution of aluminum structures"

For certification purposes, the first part of the standard, concerning the assessment of conformity of the manufacturer's declared performance of components, is used. It has been harmonized with the EU Construction Products Directive 89/106/EEC.

From July 1, 2014 (after the transitional period), its requirements are mandatory for all steel and aluminum structure contractors wishing to place their products on the EU market.

The EN 1090 standard requires manufacturers to CE mark their metal structural components intended for use in steel, aluminum, or composite steel-concrete structures placed on the European Union market. To apply the CE mark, the manufacturer must first conduct a mandatory conformity assessment of the product in accordance with EN 1090-1 guidelines and have an implemented and certified Factory Production Control (FPC) system. What structural elements do the requirements of EN 1090 apply to?
According to Section 1 of EN 1090-1:2009, the mandatory requirements of the standard relate to the conformity assessment of:
• the performance of structural elements and assemblies of steel or aluminum placed on the construction product market
• structural elements and assemblies of steel or aluminum placed on the construction product market
• steel elements used in composite and reinforced concrete structures
• elements used directly in building structures or as structural element assemblies
• structural elements and assemblies manufactured in series and non-series production
• elements made of cylindrical structural products, cold-formed or using other technologies
• elements manufactured from various sections, flat products (sheets and strips), bars, castings, and forgings of steel or aluminum materials, with or without corrosion protection by coatings or other surface treatments.

Benefits of implementing the requirements of the EN 1090 standard regarding FPC:
• Meeting the standard is a prerequisite for placing a product on the EU market
• Compliance with EU laws and regulations
• Reduction in the number of production errors
• Possibility to place your CE-marked products on the EU market
