Quality, safety and sustainability: guaranteed to the highest standards
At Heat Matrix and Bos Nieuwerkerk, we ensure the quality and safety of our products through a wide range of certifications.

Our EN 1090-1 certification enables us to issue the CE mark, demonstrating that our steel structures comply with the Construction Products Regulation (CPR). This regulation sets strict requirements for safety and environmental performance. We are also certified according to EN 13084-7, the product specification for steel chimneys, and have achieved FPC certification (Factory Production Control).
In addition, we operate under ISO 3834-2, an international quality assurance system for welding. This means our welding procedures (EN-ISO 15614-1) and welders (certified to EN-ISO 9606-1 and EN-ISO 14732) meet the highest international standards. In the area of occupational safety, health and environmental care, we are VCA** certified. Our ISO 9001 certification confirms the efficiency and effectiveness of our quality management system.
Beyond strict compliance with quality and safety regulations, we place great value on a positive working culture. The well-being of our employees is key — we believe a safe and pleasant working environment contributes directly to both job satisfaction and the delivery of high-quality products and services.
