The work an architectural sheet metal worker performs is a combination of technical skill and artistry. Our members specialize in fastening and joining, managing expansion and contraction, sealing, and controlling moisture. This ensures the appearance and durability of buildings in the institutional, commercial, industrial, and residential sectors.

Our members perform siding and decking and are involved in the application of vapour and air barriers, insulation, specialized sheeting, architectural panel systems, cladding, and decking products on construction projects. Siding and Architectural panels typically appear as part of the outer shell of a building, while decking usually takes the form of sheets of metal placed on the beams that make up the building skeleton. A deck provides the structural support for a roofing system.
