And in marine or corrosive environments, the rust-resistant doors offer long-term protection.

The industrial sliding door features a molded double steel door surface. The outer coating is polyester with high-temperature treatment, enhancing its resistance. The middle is filled with polyurethane insulation, with a door thickness ranging from 40 to 50mm. This construction makes the door solid, providing excellent insulation, thermal insulation, dust-proofing, and wind resistance. The rail is made of galvanized steel sheet, strengthened by an external torsion spring balance system that has a remarkable lifespan of over 50,000 times. It adopts both internal and external seal-tight methods, effectively preventing frost, moisture, and ensuring good heat insulation.

When it comes to security, the door is equipped with advanced safety features. It has an airbag bounce apparatus and infrared sensing function. Whenever the door encounters resistance or obstacles during its operation, the safety device automatically triggers, causing the door to rebound. This mechanism is crucial in avoiding potential damage to pedestrians and vehicles, safeguarding the safety of people and property in the vicinity. Overall, Hongfa overhead sectional doors combine functionality, durability, and safety in one comprehensive package for a wide range of industrial and institutional applications.
