The Hong Kong-Zhuhai-Macao Bridge Utilized Rock Wool Panels In Construction

The Hong Kong-Zhuhai-Macao Bridge is the world's longest sea bridge, with a total length of 55 kilometers. During its construction, architectural multi-functional rock wool boards were used in important parts such as the port buildings in Hong Kong, Zhuhai, and Macao. The use of these rock wool boards is mainly due to the following excellent properties.

Outstanding thermal insulation performance

The port buildings of the Hong Kong-Zhaui-Macao Bridge have a large area, and thermal performance is a key requirement. The architectural multi-functional rock wool boards have a low thermal conductivity and can effectively block heat conduction. Whether it is the hot and humid climate in summer or the relatively cold climate in winter, they can maintain a relatively stable indoor temperature, creating a comfortable environment for tens of thousands of travelers using the facilities, and at the same time, helping to save energy.

Excellent fire resistance

Rock wool boards are Class A non-combustible materials, which can withstand high temperatures above 1000 degrees Celsius. In case of a fire, they will not burn, nor will they release toxic and harmful gases, which can effectively prevent the spread of fire and ensure the safety of personnel in the port buildings.

Good sound insulation effect: The open porous fiber structure of the architectural multi-functional rock wool boards endows them with excellent sound insulation performance. It can reduce the interference of external noise, create a relatively quiet environment in the port buildings, and is conducive to the smooth progress of various work and the comfort of passengers.

High durability

The rock wool boards have good dimensional stability and can maintain excellent performance characteristics throughout their life cycle. Even in the harsh marine environment of the Hong Kong-Zhaui-Macao Bridge, where there are frequent storms, rainfall, and large temperature changes, they can still maintain their original performance, without significant deformation, aging, or other problems, reducing maintenance costs.

Strong water repellency

The water repellency rate of the architectural multi-functional rock wool boards is as high as 99.5%, and they also have excellent breathability. This can prevent the intrusion of moisture, ensure that the structure is dry, and avoid problems such as mildew and corrosion of the building structure caused by moisture, which is of great significance for the long-term use of the bridge in a marine environment.
