Products and Services...

Tangent Air offers both single wall and double wall, round and oval, spiral and longitudinal seam duct and matching fittings. These products are available in galvanized, stainless steel, aluminum, paintgrip, polyvinyl coated, and cabon steel. We also make "manifolds," a combination of duct and fittings components factory assembled to minimize field joints. All galvanized products can be ordered individually by gauge and type of construction or ordered according to class of service such as SMACNA High Pressure Duct Standards or SMACNA Low Pressure Duct Standards.

Tangent Air products are available in Galvanized (G90) steel, carbon steel, 304 and 316 stainless steels, aluminum (300H14), and polyvinyl coated steel. Galvanized spiral duct and fittings are offered in both high and low pressure SMACNA gauges as standard Tangent Air product lines.

All duct and fittings are fabricated of galvanized steel meeting ASTM-A527. Duct is spiral lockseam construction. Fittings are fabricated with "offset" circumferential joints to maintain diameter tolerances. All fitting seams are standing seam, welded seam, or spot welded and bonded seam construction as required by SMACNA standards. All tee and lateral tap entrances are fabricated with rounded entrances, free of weld build-up, burrs, or irregularities. All galvanized welded areas are coated with corrosion resistant aluminum paint.
