Manufacturing

We manufacture flat duct and EN 523/524-compliant galvanized round duct at our own production facility.

Corrugated galvanized duct delivery for on-site installation

Ducts are made from bright or galvanized steel sheathing or plastic materials. Their outer surfaces are corrugated to improve bond with the surrounding concrete.

Duct dispatch and quality control

We manufacture flat duct and EN 523/524-compliant galvanized round duct at our production facility. Round ducts are dispatched only after EN 524 quality control testing is completed.
