SASCO offers welded duct in Black Steel and Stainless Steel for special application requirements.
Black Steel Ducting
SASCO Black Steel Ducts (MS Ducts) are fabricated from hot rolled or cold rolled black steel sheets with fully welded construction to achieve leak proofing. The high quality mild steel contains 0.16–0.29% carbon being neither brittle nor ductile. 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.
