The doors’ many available options allow customization to your specific application and aesthetic requirements.
Our model 418 insulated sectional steel doors are built for exceptional strength and maximum life. The doors feature heavy gauge, hot-dipped galvanized steel exteriors, and 16-gauge steel center and end stiles. 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.
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.
