Duct, stainless steel duct can be divided into two kinds of round and rectangular. According to the different requirements of the project site, the production of various shapes, various specifications and finished sheet air duct. The main materials of stainless steel duct are: SUS304, 316, 303, 310, 310S, 301, 302, 304L, 316L
, 321, 201, 202, 902, 904, 317, 430 and so on. Stainless steel duct surface properties mainly include 8K mirror plate, colored stainless steel plate, stainless steel frosted plate, stainless steel brushed plate, stainless steel pattern plate, stainless steel etching plate, titanium, snowflake sand, 2B plate, BA plate and industrial[1] medium thick plate. Because of its excellent corrosion resistance, heat resistance, high strength and other physical and chemical properties, the finished stainless steel duct is mainly used in a variety of airtightness requirements of the process exhaust system, solvent exhaust system, organic exhaust system, exhaust exhaust gas exhaust system and the outdoor part of the general exhaust system, hot and humid exhaust system, smoke exhaust and dust removal system and so on.
