Product Description

Product Description

 

The Nhentrance sectional door is crafted from double-layered steel for unparalleled strength. The door panels have high-temperature-resistant polyester paint, look sleek, and provide exceptional durability. A thick layer of polyurethane foam ensures superior insulation, keeping your space warm in winter and cool in summer.

The door's robust construction continues with a heavy-duty hot-dipped galvanized steel track and an external torsion spring system designed to last over 50,000 cycles. Dual seal strips keep out the elements, ensuring airtightness and energy efficiency.

Safety is our priority, with features like airbag-based anti-pinch protection or infrared sensors that automatically reverse the door upon detecting an obstacle, safeguarding people and vehicles.

Available in multiple sizes and configurations, our sectional door adapts to any industrial environment, from warehouses to workshops, offering convenience and reliability. With NHentrance, you get a door that stands the test of time.
