Overhead sectional doors are essential for modern industrial facilities, providing security, insulation, and efficient access. The door leaf consists of horizontally connected sandwich panels that open vertically, sliding up under the roof to save floor space. Constructed from 40mm thick pre-painted galvanized steel panels with high-density insulation, these doors offer excellent thermal efficiency (1.60 W/m2K). They are designed to withstand high wind loads (up to 118 km/h) and frequent usage. Available in various lift systems (Normal, High, Vertical) to suit different building structures, they ensure optimal space utilization around the door opening.
