HVAC ductwork

We manufacture duct and fittings in round, flat oval (for space restrictions), and rectangular configurations. Round and flat oval configurations are available with either single-wall or double-wall, insulated constructions. Our rectangular duct and fittings are available as single-wall, unlined; single-wall, lined with insulation; or as double-wall, insulated. A variety of diameters, lengths, gauges, and metal types are available. Our fittings are designed to have minimum static pressure losses and to be interchangeable among Spiro Metal Inc different duct types.

Spiro Metal Canada Inc pioneered the manufacture of spiral lock seam duct and specializes in its production. Our spiral lock seam duct is offered in a wide range of gauges, making it easy and economical for users to meet industry standards. An interlocking helical seam runs the entire length of the duct, adding structural strength while maintaining a smooth, obstruction-free interior. Spiral lock seam duct is machine-formed and known for its uniform size and quality, predictable performance, easy installation, and almost total elimination of leakage. Fittings are available in a variety of gauges to match the duct line. We also offer spiral lock seam duct with a standing rib. Single-wall duct and double-wall duct are manufactured with an external stiffening rib for added strength and rigidity. Ribbed duct saves you money by letting you use lighter gauges that are as strong as heavier gauges of standard duct. This duct costs less and is easier and less expensive to install. For applications involving heavier-gauge materials or very large-diameter constructions, we offer Longitudinal Seam (solid-welded) duct.
