description The utility model discloses a marine galvanized sheet air duct for a cabin. The air duct is rectangular and tubular. Outwards-raised reinforcing edges (1) are pressed transversely at an equal interval on the galvanized sheet air duct. Strip-type galvanized sheet reinforcing ribs (2) are fixed on the inner wall of the air duct. Reinforcing ribs (2) are also fixed around a branch pipe orifice of the air duct. Angle steel flanges are arranged at the two ends of the air duct. The conventional air duct is replaced by the galvanized sheet air duct with the thickness of 0.7 to 1.2mm, the surface of the air duct is enhanced by the outwards-raised reinforcing edges, and for a large-sized air duct of which the annular outwards-raised reinforcing edges cannot meet requirements, the longitudinal reinforcing ribs are riveted on the inner surface of the air duct, so that the strength of the air duct is the same as that of a thick iron air duct. The corrosion resistance of the surface of a galvanized sheet is higher than th
