产品详细信息
Drawn to a variety of diameter sizes and available in bright, galvanized and bronze coating, duct wire provides the “skeleton” structure for the duct. The wire is bent and shaped into a loose, flexible coil, forming a framework over which the insulation and membrane material is wrapped, allowing the duct to bend around corners without constricting air flow.
