Please come in if you have experience as a fiberglass ventilation duct installer.

There are several types of ventilation ducts, including galvanized steel ducts, welded ducts, fiberglass ducts, and composite ducts. The commonly used ones are galvanized ducts. This work is okay, and the technician's salary is about 120 yuan/day. The installation of fiberglass air ducts is not very good. The first air duct is too heavy and tiring. The second flange needs to be drilled, there is dust and it is too dirty.
