Optional Performance Package
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.
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.
