EN 1090 Steel Structures

EN 1090 is a European standards series that encompasses certification requirements and regulations for the production and assembly of structural steel and aluminum products. This standard series is used in the construction industry with the aim of ensuring the safety and compliance of products and structures. EN 1090 certification is geared towards guaranteeing the appropriate design, manufacturing, and assembly processes of structural steel and aluminum products. Here is more information about EN 1090:

Key Elements:

Certification Classes

The EN 1090 standards series defines different certification classes for various structural steel and aluminum products. These classes vary depending on the complexity and intended use of the products. The requirements for a specific class encompass design, manufacturing, assembly, and inspection processes.

Manufacturing Control

EN 1090 certification aims to verify that products are manufactured properly and that manufacturing processes comply with the required standards. This may necessitate regular inspections of manufacturing workshops and facilities.

Quality Management System

Businesses seeking EN 1090 certification may be required to manage their manufacturing processes within a specific quality management system framework, often based on ISO 9001.

Technical Documentation

Technical documentation is required to demonstrate the compliance of products. This documentation may include design specifications, manufacturing procedures, welding procedures, and other relevant documentation.


EN 1090 certification requires traceability at every stage of the product’s lifecycle. This involves maintaining records for all processes, from production to assembly.

CE Marking

EN 1090 certification mandates the use of the CE marking on products. This marks the products as compliant with specific standards within the European Union market, indicating their compliance and safety.

EN 1090 certification is crucial for ensuring the safety and quality of structural steel and aluminum products used in construction projects. It may be mandatory for companies operating in the construction sector and plays a significant role in the availability of compliant products and structures. Obtaining this certification can help businesses competitively present their products in both domestic and international markets.

EN ISO 3834: Welded Manufacturing Quality Standards

EN ISO 3834 is a series of standards designed to enhance the quality and reliability of welded manufacturing. These standards are used to ensure compliance throughout all stages of the welding processes. These stages include:

Design: Ensuring the suitability of the welding process during product design. Material Selection: Selecting appropriate welding materials and conforming to specific requirements. Welding Process: The welding process and operator suitability. Inspection and Certification: Quality control processes and certification requirements.

EN ISO 3834 provides guidelines and requirements for ensuring compliance in these stages and defines quality management systems.

EN 15085: Welding Applications Standards for the Rail Transportation Sector

EN 15085 comprises a series of standards for welding processes used in the production of railway vehicles and components, particularly in the rail transportation sector. These standards have been developed to meet safety and quality requirements in the rail transportation industry. EN 15085 addresses the design, production, testing, and certification stages to ensure the compliance of welded components with specific quality standards.

The compliance assessment process may include:

Identification of Relevant Standards: Identifying the standards applicable to the product or process. Certification of Welding Processes: Documenting the compliance of welding processes, authorizing operators, and providing required training. Quality Control and Monitoring: Establishing and implementing quality control processes during product manufacturing. Certification: Formal certification of compliance with standards such as EN ISO 3834 and EN 15085.

In conclusion, standards like EN ISO 3834 and EN 15085 are essential tools to improve the quality of welded manufacturing and ensure compliance. Compliance with these standards can enhance product safety, durability, and market acceptance, making them critical for welded manufacturing businesses

EN 15614-1 WPQR (Welding Procedure Qualification Record):

EN 15614-1 is a procedure for the qualification and certification of welding processes. WPQR is used to document the competence and qualifications of a welder or welding operator for a specific welding process. The key elements of this standard are as follows:

  • Test Specimens: Laboratory tests are conducted to qualify the welding process. These tests demonstrate that the welding process has been successfully performed by the welder and conforms to specific standards.
  • Qualification Report: A qualification report is prepared based on the test results. This report includes detailed information about the welding process and the approved parameters.
  • WPQR Certificate: Following a successful qualification, a WPQR certificate is issued for the welding process. EN 15614-1 WPQR is used to ensure the safety and quality of welding processes and provides formal documentation for a welding process or welding operator. These standards are essential for regulating and ensuring the quality of welded manufacturing processes, contributing to the industry’s reliability.
  • Welding Procedure Specification (WPS): WPS, as a procedure document for the welding process, defines how a specific welding process will be performed, which parameters will be used, and what properties the materials should have. This ensures the repeatability and safety of the welding process.

EN ISO 9606-1 Welder Certification:

EN ISO 9606-1 is a standard used to certify the competence of welders. This standard includes welding tests to demonstrate a welder’s suitability and competency for a specific welding process. Here are some key elements:

  • Welding Tests: Welders undergo welding tests to demonstrate their suitability for a specific welding process. These tests assess the welder’s capabilities and skills in performing the welding process
  • Certificate Issuance: After successfully passing a welding test, welders are awarded certificates compliant with EN ISO 9606-1. These certificates indicate that welders can perform a specific process safely and with quality.
  • Certificate Validity: Welder certificates are valid for five years and may require annual reevaluation.
