I am an apprentice in painting. I don't want to learn. I want to learn sheet metal. I think sheet metal work is not a fine work, but a rough work. I want to try sheet metal, but I don't know much about sheet metal. It's the first time I heard that sheet metal work is a rough job. Do you think sheet metal work is a sledgehammer? Then you are wrong. The requirements of sheet metal work are more complicated than painting.

Let me introduce to you: according to the actual needs or drawings, sheet metal workers cut all kinds of plates or profiles to form all kinds of required three-dimensional components, such as ventilation pipes in buildings, cyclone dust collectors with big bends and small joints in factories, plastic repair of automobile repairs and various civil white iron products.

Sheet metal workers need profound knowledge of mathematics, geometry, metal welding, cutting, locksmith, riveting and so on.
