Overhead Doors Built for Long-Term Durability

Its mechanically interlocked skins and continuous steel overlap provide superior structural integrity and secure hardware attachment, making it a reliable choice for commercial and industrial applications.
Made with Canadian Steel
Exceptional Thermal Performance for Insulated Doors
Designed with energy efficiency in mind, the Therm-O-Door features a unique Therm-O-Break design that minimizes the transfer of heat, cold, and moisture. A flexible floor seal adapts to uneven surfaces, effectively blocking out drafts and debris. Insulated windows with sealed lites and high-impact polymer frames help maintain interior temperatures while allowing natural light to enter.
Low Maintenance, High Appeal Sectional Doors
The door’s finish includes a factory-applied, baked-on two-coat polyester paint that offers years of maintenance-free performance. This durable coating resists wear and weathering, and the door can be painted to match your building’s exterior for a cohesive look.
Heavy-Duty Overhead Door Options for Industrial Needs
For environments that demand extra strength, the TD134-20 model includes a 20-gauge exterior face. This heavy-duty option is ideal for industrial settings where durability and resilience are critical.
Customizable Track and Hardware Systems for Overhead Doors
A variety of track systems—including Standard, High Lift, Vertical Lift, and Low Lift Double Track—to suit different installation needs. Heavier doors are equipped with 3” tracks and heavy-duty rollers, ensuring smooth and reliable operation even under frequent use.
Add Custom Door Signs
Make it easier and quicker to identity dock and door positions with custom made doors signs with your company’s logo on it. Add it to both the inside and outside of the door.
