Flexible Metal Duct
Category: Air Duct
Overview
Flexible metal duct is formed from interlocking spiral-wound metal strip that provides full flexibility while maintaining structural integrity under high-temperature conditions. The interlocking construction allows angular deflection up to 90° and accommodates vibration and thermal expansion without stress on joints. Stainless steel grade is used for exhaust temperatures up to 550°C.
