Ventilation Air Duct Metal Steel Clamp With Screw — designed for secure, fast, and reliable connection of round ducts and fittings. We supply a wide range of duct clamps in sizes from Ø80mm to Ø800mm, made from galvanized steel or stainless steel 304.
Key Applications: These ducts, pressed bends, and fittings are widely used in grain, seed, and corn conveying systems, vacuum and pneumatic transport, agri-vac machinery, and dust or fume extraction systems.
Our stainless steel 304 straight ducts are produced by laser welding or argon arc welding (TIG) for smooth seams and excellent sealing performance. Typical edge height is 6–7 mm with thickness ranging from 0.8–1.5 mm.
