Certifications and Quality Seals in the Metal Window and Metalworking Sector
2026-04-14
Discover the key certifications that ensure quality, safety, and technical compliance in the metal window and metalworking sector.
For a metalworking company to compete with technical credibility—differentiating itself in both public and private projects—it is essential to hold a solid set of certifications and recognitions that demonstrate its performance, management, safety, and market positioning. Companies with this type of certified portfolio are able to reduce technical and legal risk for clients, increase cost and timeline predictability, gain access to more technically complex projects, and strengthen the technical and institutional reputation of both partners and developments.
Below are the main Technical Certifications and Industry Recognitions:
CE Marking (European Product Conformity)
What it is:
CE Marking is mandatory in the European Union for construction products, including window systems and metal frameworks, certifying compliance with harmonized European performance and safety requirements.
What it certifies:
- Safety of use and regulatory compliance

- Safety, health, and regulatory requirements
Advantages:
- Provides technical and legal confidence to clients, projects, and inspections
- Enables free circulation of products within the European market
- Strengthens competitiveness and acceptance in public and private tenders
Fire Certification (Fire Performance)
What it is:
Certification according to EN 16034 + EN 14351, based on laboratory testing conducted by accredited external entities and specific standards, evaluating the behavior of metal systems in case of fire. Classifications include EI30, EI60, EI90, and EI120. Essential in regulated environments.
What it certifies:
- System integrity under fire exposure
- Thermal insulation capacity for a defined period during a fire
- Structural stability in emergency situations
Advantages:

- Strong added value in projects with high safety requirements (e.g., hospitality, healthcare, education, public buildings)
- Reinforces institutional and regulatory confidence
ANEPC Certification (National Authority for Emergency and Civil Protection)
What it is:
Recognition of compliance with national safety and civil protection regulations, applicable to construction solutions impacting building evacuation and safety.
What it certifies:
- Commercialization and installation (not production) of certain fire-rated systems sourced from certified manufacturers
- Compliance with national safety regulations regarding emergency planning and risk protection
Advantages:
- Facilitates technical validation during licensing and inspections
ISO 9001 – Quality Management System

What it is:
Balustrades composed of coated perimeter metal profiles, with infill in fire-resistant safety glass—featuring high-performance European fire protection classification.
This system provides an elegant solution to façade opening separation distances required for fire protection, as defined by technical regulations (Ordinance No. 135/2020), which establishes minimum distances of 1.1 m or 1.5 m between vertically aligned openings (different floors) of separate fire compartments.
What it certifies:
- Mechanical resistance for residential and service environments
- Fire performance, as it is entirely composed of fire-resistant materials
- Compliance with NP 4491:2009, with mechanical resistance testing
Advantages:
- Proven in-house capability for proprietary product development in the window systems sector, particularly fire-rated systems
- High structural and fire safety
- Integrated and tested solutions for high-use environments
- Reduction of technical liability risks
IMPIC (Institute for Public Markets, Real Estate and Construction) – Public Works Contractor License No. 88127 - PUB
