Certified welding manufacturer in line with DIN EN 1090-2

Zertifizierter Schweißbetrieb nach DIN EN 1090-2 In July 2013, the former Construction Products Directive was replaced with the new European Construction Products Regulation (CPR). Since then, all construction products placed on the market have to comply with the CPR regulations. These regulations primarily focus on the provision of a written declaration of performance and modified CE marking.

As of 1/1/2011, structural steel and aluminium components can only be traded with a CE marking if their CE-conformity has been assessed. Henceforth, the EN 1090 standards will also replace the German technical requirements DIN 18800-7 and DIN V 4113-3.

As of July 2014 – when the coexistence period expired – manufacturers of structural steel and aluminium components have to be suitably certified to trade their construction products on the German and EU markets.

As of July 2014 at the latest, companies that produce structural steel and aluminium components must comply with the European Construction Products Regulation (CPR, formerly Construction Products Directive) in conjunction with DIN EN 1090-1, which has been harmonised since the end of 2010, and may only trade construction products on EU member state markets if they are CE-marked. To be able to do so, companies must have their production facility and internal production control systems certified and monitored.

Certification does not just demonstrate that a company’s personnel is qualified and that it has the requisite equipment, but also that its components and products have the specified essential properties.

Certification is an essential requirement for CE-marking of steel and aluminium building components and the associated permission to freely trade goods within the EU.


DIN EN ISO 3834-2 quality requirements for welding
(Comprehensive quality requirements)

Zertifizierter Schweißbetrieb nach DIN EN 1090-2

The international standard series DIN EN ISO 3834 et seq. sets out welding quality requirements for manufacturers and defines the fundamental principles for ensuring the quality of fusion-welded components and structures. DIN EN ISO 3834 governs welding in series production, single-item production, repair and welding performed on construction sites (assembly), and applies to all welding-related areas of application. It covers all of the requirements for welding-related quality management systems and is simultaneously the basis for compliance with the requirements of standards governing specialised welding applications such as EN 1090-1 and EN 15085-2.


Energy management certified in line with DIN EN ISO 50001

ISO 50001

ISO 50001 is an international standard designed to help organisations take a systematic approach towards achieving energy efficiency. ISO 50001-certification also demonstrates that an organisation’s energy management system complies with the standard’s requirements.
Systematic approaches to energy management are based on analysing all energy flows within a company (energy sources, energy use, energy consumers) and assessing energy efficiency particularly with respect to equipment and processes that consume a significant percentage of the energy used. This analysis is used as a basis for implementing both technical measures for improving energy efficiency as well as strategic and organisational approaches to energy management. Both organisational and technical measures need to be aimed at systematically and sustainably improving energy-related performance to protect valuable resources.
