GALVANIZED METAL OBJECTS AND THEIR MANUFACTURING PROCESS

摘要

This invention provides process for manufacturing a galvanized metal three-dimensional object with a shape including multiple edges, said process comprising, 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 said metal sheet matrix including multiple free edges,(B) batch-wise hot dipping said 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 said multiple adjacent metal edges, to form said galvanized metal three-dimensional object.
