Strong, Lightweight, Attractive and Durable.

Thermacore® 591 sectional steel doors feature roll-formed, hot-dipped galvanized steel exterior panels designed for exceptional strength and sound suppression capabilities. Wind load design available for usage in high-wind conditions. Two coats of baked-on, polyester paint on a ribbed, textured exterior surface provide a handsome finish lasting for years. Our industry-leading 10-year limited warranty against delamination means that we’ll stand behind the quality of our doors at the outset and for the long haul.

Superior Field Serviceability.

Thermacore® has a special internal construction that allows hinges to be placed anywhere along the panel’s length, permitting customization on the job site. This allows for fast and precise installation, repair, or retrofit.

Built With the Best Technology in the Business.

This sectional steel door is manufactured using Overhead Door Corporation’s proprietary, computer-controlled fabrication process. This advanced technology ensures adherence to the industry’s strictest product tolerances and results in an exceptionally well-built door for outstanding thermal efficiency and long-lasting performance.

Many Options, Better Solutions.

The Thermacore® sectional steel door model 591 fits openings up to 35’2″ (10.7 m) wide and 24’1″ (7.3 m) high. A full line of electric operators ensures precise and trouble-free motor operation in various mounting options (side, center or trolley). Available options include an aluminum sash section, thermal glazing, pedestrian pass door, impact panel, and jamb weatherstripping. Optional high-usage components expand the versatility of the 591 to high-cycle conditions, with torsion springs in 25k, 50k, 75k, or 100k cycles, a solid-steel shaft to reduce fatigue and deflection, and a heavy-duty 3″ (76 mm) steel track for added durability.
