When your project requires a solid sectional steel door system that will hold up to heavy use, rough handling and extreme conditions look to Overhead Door Corporation’s 418 to pack an extra measure of toughness. Fabricated of 16 or 20-gauge galvanized steel for strength and durability these doors feature an attractive flush exterior finish as well as a tough 26-gauge back cover for rugged good looks in any environment. 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.

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/m2). These sectional doors also feature a back cover of 26-gauge galvanized steel for added protection against thermal transfer.

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.
