Product Features

■ The emergence of Haolan hard fast doors has brought a new concept of industrial doors, and the technology is at a leading level. Metal high-speed rolling doors can maintain good sealing performance under both high and low pressure. And it can withstand strong wind attacks, and the opening speed of the door varies with size, reaching up to 2.5m/s at the fastest.

■ Has high practicality, reliability, durability, ease of operation, and low noise characteristics. It is a popular choice for busy entrances and exits in various fields such as chemical, pharmaceutical, automotive, and food processing.

■ The spiral circular contact accumulation track ensures that the door curtain does not come into contact with each other when rolled up, and the material of the door curtain remains free from wear and deformation. It operates with low noise and fast speed.

■ The high-speed drive motor is controlled by a frequency converter and a microprocessor. In the event of a power outage, the internal tensioning mechanism can be manually operated to open the door.

■ Full transparent Flat noodles can also keep clear and transparent for years. The Flat noodles is designed as a template and can be replaced at any time. The performance of strong wind resistance, high sealing, and low noise is unmatched by other products.

■ The hard fast door turbine guide rail is beneficial for the acceleration of the door body, making it smoother during high-speed operation and reducing noise generation. And our company adopts a dual turbine structure that is superior to other companies' single turbines, with a higher safety index. Multiple rows of hinges are fixed with specially designed bolts, and the connection of the hinges is made by combining QP treated steel shafts with PEEK shaft sleeves, which increases the surface hardness of the shaft and greatly enhances its corrosion resistance. The surface of the shaft is smooth, not easily corroded, and has high strength for use.

■ This product has high reliability, practicality, ease of operation, and fast repair characteristics. The drive control adopts a stable, energy-saving, and accurate hard fast door system to ensure the reliable operation of the door body, ensuring more than 50000 fault free operations per year.
