Sasco’s Black Steel Ducts (MS Ducts) are fabricated from hot rolled or cold rolled black steel sheets with fully welded construction to achieve leak proofing complying to NFPA standard and local codes. In kitchen exhaust MS ducts are largely used owing to its inherently fire resistant characteristic. The aesthetic of the duct is enhanced by applying three layer of Red Oxide paint. ​

Mild steel ducts are available in various thickness and various finish.
