The aluminum Overhead Sectional Garage Door is a versatile and cost-effective solution suitable for a variety of applications. Hongfa's sectional doors are ideal for projects requiring high insulation, such as LEED-certified facilities, as well as security installations for police and military facilities, and specialized use in industries like mining (iron, nickel, diamond) and aviation (airport hangars).

These industrial sliding doors boast a durable design, featuring a molded double steel surface treated with polyester at high temperatures. They are filled with polyurethane insulation, providing a door thickness of 40-50 mm for superior strength, thermal insulation, and resistance to dust and wind. The use of galvanized steel in the rail system enhances durability, while a torsion spring balance system is engineered for over 50,000 cycles of operation.

Additionally, these doors are equipped with internal and external seals to protect against frost, moisture, and heat. For enhanced safety, they include an airbag bounce system and infrared sensing technology, which ensures that the door automatically rebounds upon meeting resistance or obstacles, effectively preventing harm to pedestrians and vehicles.
