Spiral Ducts & Custom Fittings

Our ducts can be produced in diameters ranging from less than 80 mm up to 1,400 mm, ensuring maximum flexibility for a wide variety of applications.

In addition to spiral ducting, we manufacture a complete range of custom components, including flanges, bends, reducers, branches, rain caps (“Chinese hats”), and other special fittings designed to meet specific project requirements.

Thanks to decades of experience, advanced production technologies, and skilled craftsmanship, we guarantee precision, durability, and excellent performance in every product we deliver.

Over the years, Metalmeccanica Palozzi has supplied ducting systems for major infrastructure projects, including the construction of Rome’s Metro C, demonstrating our ability to meet the demanding standards of large-scale engineering and construction works.
