Our manufacturing activities are certified by ÉMI, ensuring the reliability and high quality of our products. Our air ducts are produced from galvanized steel sheets in accordance with EN 10142 standards, in airtightness classes “B” and “C”. Our heat- and smoke-resistant HVAC systems are also manufactured using high-quality galvanized steel sheets in compliance with the relevant standards, meeting the highest technical and safety requirements. The assembly of galvanized steel air duct components is carried out using modern seam-locking technology, resulting in durable and precise joints.
For applications in greasy or oily environments, we manufacture welded, so-called “black” air duct components from S235-grade steel sheets with varying thicknesses. For specialized industrial environments, we offer stainless steel air ducts with outstanding corrosion resistance and long service life.
For us, quality is not just an expectation but a core value. Our products are backed by precise manufacturing, high-level expertise, and continuous development. Our employees receive regular training, and quality control is integrated into our production processes, ensuring that every product leaves our facility under strictly controlled conditions.
Our own inventory ensures that we always have enough raw materials in stock for at least six months, allowing us to guarantee reliable delivery times.
We view our partners not as customers, but as allies. Our goal is shared success and the establishment of long-term collaborations that both parties can be satisfied with and proud of. As part of this, we support our partners with professional consulting, and upon request, we provide free airtightness testing for HVAC systems built using our manufactured components.
We operate an internal quality assurance system.
This certificate confirms that our products comply with the performance requirements specified in Annex ZA of the EN 12101-7:2011 standard, as well as with the requirements for the assessment and verification of constancy of performance.
