A tinsmith designs and makes objects from thin plates, either according to his own drawings or those of others. The job involves installing roof, wall and steel frame cladding as well as ventilation systems, building individual system components, and servicing and maintaining such systems. Tinsmithing is a certified trade.
Tinsmiths also custom-build various utility items, such as trailers and fire doors, and advise customers on material selection and installation. Tinsmiths often work for production, service and contracting companies.
