CECO KB Duct is a leader in standard, modular ducting systems (clamp-together and flanged), individual components and application-specific duct solutions for industrial dust, fume, mist and air handling systems. KB Duct began as a part of CECO Kirk & Blum brand, which has been in operation since 1907.
We offer fast delivery on clamp-together duct from 3” to 24” in 22-gauge to 10- gauge, depending on diameter, and flanged duct in diameters you can drive a truck through as heavy as 1/4” material. CECO KB Duct’s workforce maintains the highest quality manufacturing standards.
CECO KB Duct offers duct with and without flanges (angle rings) in black iron, galvanized or stainless steel, and with or without holes. We can manufacture flanged duct from 3” all the way up to the size you could drive a truck through, and we can manufacture lighter gauges to fully welded product in heavy gauge (even up to 1/4”), all depending upon the application.
The term Vanstone flanged duct refers to a technique where flanges are placed onto the pipe, with the lip turned back at 90 degrees and left loose for a secure metal-to-metal connection when the flanges are pulled together and the Vanstone lips are connected. This allows for easy alignment of the centerline of the components. Premium quality materials are designed to hold up even in harsh environments and offer very low total cost of ownership.
