The present invention provides a method for manufacturing a galvanized metal three-dimensional object with a shape including multiple edges. The method comprises, in the following order, the steps of: (A) providing and cutting a metal sheet matrix with a thickness within a range from 0.8 mm to 6 mm, the shape of the metal sheet matrix including multiple free edges; (B) batch-wise hot dipping the metal sheet matrix into a molten zinc alloy galvanizing bath; (C) cold-forming the galvanized metal sheet matrix into a desired three-dimensional shape including multiple adjacent metal edges; and (D) cold-forming a series of joining points for fastening together the multiple adjacent metal edges, to form the galvanized metal three-dimensional object. |
