Semi-Flexible Manufacturing
Semi Flexible Duct Machine
An automated machine for producing aluminium and stainless steel semi-flexible ducts with consistent dimensions and superior construction.
Semi-flexible duct bends to complex layouts while holding its shape - suited to HVAC, industrial and commercial ventilation. Automated production keeps quality consistent at a lower cost than manual methods.
