Our model 422 insulated sectional steel doors are ideal for heavy-duty applications requiring protection against the elements. These insulated sectional steel doors feature a 16-gauge steel intermediate and end stiles and ribbed steel exterior and 26-gauge steel back cover in a white finish.

These sectional steel doors offer the benefit of insulation for applications where enhanced thermal efficiency is desired. The standard expanded polystyrene provides R-values of 7.35 (1.29 W/Msq). These sectional doors also feature a back cover of 26-gauge galvanized steel for added protection against thermal transfer.

Superior panel strength and a heavy-duty, tight-fitting 2” (51 mm) track combine to meet local windloading requirements. Rabbeted meeting rails ensure weathertight joints and provide full-width interlocking structural rigidity. Precision-manufactured galvanized steel track, hinges and fixtures ensure long life and low maintenance. A baked-on polyester paint finish eliminates job-site painting and provides added protection against the elements.

These sectional steel doors offer plenty of options to meet your aesthetic and functional requirements. You’ll have the choice of full-sash section or individual-panel glazing to control the amount of light infiltration and permit visitor identification. Bracket mounting is available (except on full vertical doors). A variety of bottom strips and jamb weatherseals minimize air infiltration and accommodate any number of field conditions, including sloping grades.

These sectional steel doors offer an optional package that improves door performance and durability for doors with high-usage cycles. This special application package has three key components for added strength and durability: high-cycle torsion springs in 25K, 50K, 75K or 100K cycles, a solid-steel shaft to reduce fatigue and deflection, and a heavy-duty 3” track. Also available is an integrated line of electric operators designed specifically for these heavy-duty doors, which enhances reliable performance for years to come.

The sectional steel model 422 is a 20-gauge steel door available in sizes up to 29’2” in width and 24’1” in height (8890 mm and 7341 mm). A multitude of options — including reinforcing struts, movable center posts, and motor operation — allow these insulated heavy-duty doors to be used in a variety of commercial and industrial environments.
