Industrial and Commercial Overhead Door & Thermal Sectional Door & Steel Sectional Door for Warehouse
These automatic industrial overhead sectional doors are constructed from high-quality, double-layered hot-dip galvanized steel sheets and imported energy-efficient polyurethane materials; depending on door size and specific requirements, the panels are designed without steel reinforcement backings. Certain sections of the door combine a new type of aluminum alloy with high-quality polycarbonate (PC) panels. This design not only enhances the aesthetic appeal of industrial and commercial buildings but also accommodates various high-lift track configurations.
