Industrial Sectional Door

Thermal insulation, wind resistance, and fire retardancy in one system.

Industrial sectional door with double-layer PPGI PIR sandwich panel filled with high-density foam (45 kg/m³) and 40 mm thickness. Designed for factories, logistics loading and unloading areas, food plants, electronics, and other environments requiring thermal insulation, wind resistance, and fire retardancy. Equipped with EPDM rubber perimeter seal that does not deform with weather and rejects dust and insects. The torsion spring balance system allows the door to operate with minimal power, extending motor service life and reducing maintenance. Operating speed up to 0.3 m/s.
