Vally sectional garage door

Sectional doors are widely utilized and are an economical and practical choice. They find extensive applications in various fields. For instance, Hongfa overhead sectional doors are highly suitable for LEED institutional projects, serving as excellent high insulated doors. They are also essential for security purposes in police and military installations as well as detention centers. In the mining industry, whether it's for iron, nickel, or diamond operations, these sectional doors play a crucial role. Moreover, they are used as airport hangar doors and rust resistant doors in marine or corrosive environments.

Industrial sliding doors feature a unique structure. The inner and outer surfaces are made of molded double steel with a polyester coating that undergoes high temperature treatment. The middle is filled with polyurethane insulation, providing a door thickness ranging from 40 to 50mm. This construction makes the door solid, ensuring good insulation, thermal insulation, dust-proof, and wind-resistant capabilities. The rail is made of galvanized steel sheet, and it is equipped with an external torsion spring balance system that has a remarkable lifespan of over 50,000 times. There are both internal and external seal-tight mechanisms, which effectively prevent frost, moisture, and offer excellent heat insulation.

When it comes to security, these doors are well-equipped. They have an airbag bounce apparatus and infrared sensing function. Whenever the door encounters resistance or obstacles during its operation, the safety device will automatically trigger a rebound. This crucial feature helps to avoid any potential damage to pedestrians and vehicles, ensuring a safe environment. Whether it's for commercial, industrial, or institutional use, sectional doors with such features prove to be a reliable and efficient solution. They not only enhance the functionality of the space but also contribute to the safety and durability aspects. Their wide range of applications and advanced technical specifications make them a popular choice among different industries. With continuous innovation and improvement in design and manufacturing, sectional doors are expected to serve even more diverse needs in the future, providing enhanced performance and greater convenience for users.
