Stove-Pipe manufacturing is a subdivision of the Sheet Metal Work industry that specializes in the production of pipes used for ventilation and heating systems. Stove-Pipes are typically made of galvanized steel, stainless steel, or aluminum and come in various shapes and sizes to fit different heating and ventilation systems. The manufacturing process involves cutting, bending, and welding the metal sheets to create the desired shape and size of the pipe. Stove-Pipe manufacturers also produce accessories such as elbows, tees, and caps that are used to connect the pipes and create a complete ventilation or heating system.
