Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a fireproof galvanized steel plate air duct. Background Art

[0002] Duct is a piping system used for air delivery and distribution. There are two types: composite duct and inorganic duct. Composite duct is represented by duct. It can be classified according to cross-sectional shape and material. Duct production Stainless steel duct production is to apply sealant (such as neutral glass glue) to the seams such as the bite seams, rivet seams, and the four corners of the flange. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, duct can be divided into circular duct, rectangular duct, oblate duct and other types. Among them, the circular duct has the smallest resistance but the largest height dimension and is complex to make. Therefore, rectangular duct is mainly used. According to the material, duct can be divided into metal duct, composite duct, polymer duct. Galvanized steel plate is a welded steel plate with a hot-dip or electroplated zinc layer on the surface. It is generally widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc.
