Detailed Description

1. Product Overview

Industrial overhead doors consist of double‑layer color‑steel insulated panels with a polyurethane core, offering excellent thermal insulation, soundproofing, and impact resistance. When opened, the panels fold vertically upward along tracks, occupying no space in front of the doorway while providing a tight, dust‑proof seal. Equipped with balance springs and a dedicated motor, they operate smoothly and can be customized with windows or auxiliary doors. Ideal for large openings such as factory gates, warehouses, and garages, these doors are durable, easy to maintain, and serve as versatile industrial entry points.
