Door Engineering Introduces FF70 Hurricane Door Certified for Zones Up to 65 PSF

Key Takeaways:

• Door Engineering introduced the FF70 Hurricane Door on Aug. 19, 2025.
• The door is certified for hurricane zones experiencing up to 65 PSF pressure.
• FF70 employs a four-fold panel design.
• The company says the product was “designed and rigorously tested” for demanding environments.
• The launch underscores the growing market for extreme-weather infrastructure.

A Door Built for Storms
Door Engineering, a Minnesota-based manufacturer, announced what it calls a “revolutionary” solution for high-risk hurricane zones: the FF70 Hurricane Door. “Door Engineering is proud to announce the launch of the FF70 Hurricane Door,” the company said in an Aug. 19 statement issued from Mankato. The door’s most eye-catching credential is a certification that it can endure pressures of up to 65 pounds per square foot—conditions associated with some of the nation’s fiercest coastal storms.

Four-Fold Engineering
Unlike conventional single-panel barriers, the FF70 uses a four-fold configuration. By dividing the span into multiple connected panels, the design allows for wide openings while aiming to keep structural stresses in check—an approach the company says is tailored to “the most demanding environments.”

Tested for the Toughest Environments
Door Engineering emphasizes that the FF70 was “designed and rigorously tested” before earning its 65 PSF rating. Though the firm did not disclose specific test protocols, the certification signals compliance with the pressure benchmarks that define many hurricane building codes.

Looking Ahead
As stronger storms become a regular line item on building planners’ checklists, products like the FF70 Hurricane Door point to a future in which infrastructure is engineered from the ground up for resilience. For Door Engineering, the four-fold system is the latest effort to meet that escalating demand—one panel at a time.
