Circular Ducting in Galvanized or Stainless Steel

ALWO circular ducting is manufactured from hot-dip galvanized sheet steel or stainless steel, according to the application. Materials are sourced from certified suppliers, and the double-fold longitudinal seam supports airtightness and resistance to vibration and friction.

For the galvanized-steel version shown, duct sections have a wall thickness of 0.8 mm, a standard length of L = 1235 mm and 6 mm rolled edges. The technical catalogue covers D1 diameters from 120 to 1000 mm. Sections can be joined with clamps or flanges and sealed with silicone or polyurethane sealant.

The final configuration is specified according to airflow, route, transported particulate and operating conditions. For sizing, provide ALWO with the required diameters, lengths and material.
