Quick Details

ETFE MEMBRANE ROOF SYSTEM

This project is part of the Guangzhou Macau Cooperation Zhuhai Hengqin Traditional Chinese Medicine Industrial Park project. The eaves of the membrane structure are 22 meters high, and the steel structure is made of elliptical customized steel pipes. The structure consists of six petals; The membrane material adopts German imported NOWOFOL frosted ETFE membrane material, with a simple structure and perfect shape, which is the finishing touch of the entire traditional Chinese medicine industry park.

Project Technical Solution

Structural System

The project adopts a hybrid structure combining ETFE membrane, cable, and customized elliptical steel frame. The six-petal design forms a lightweight, large-span roof, reducing structural weight and foundation loads while enhancing overall aesthetics.

Membrane (ETFE)

The roof uses ETFE membrane with high light transmission, UV resistance, and durability. Its frosted surface delivers soft, diffused daylight and excellent self-cleaning performance.

Cable System

The high-strength steel cable system works jointly with the ETFE membrane to ensure stable tension. This system offers excellent wind and seismic resistance, ensuring safety and durability under large-span configurations and diverse environmental conditions.

Project Highlights & Advantages

High-Performance ETFE

ETFE membrane delivers excellent light transmission, providing soft and natural indoor lighting. Its lightweight and flexible properties reduce structural load and maintenance costs, creating a comfortable and cost-efficient environment.

Long-Span & Structural Stability

Advanced structural design supports large-span ETFE membranes, ensuring superior safety and stability. The column-free interior provides flexible, open spaces suitable for a variety of uses.

Efficient Construction & BIM Management

Precise BIM-based planning and coordination streamline construction, minimize on-site errors, and accelerate project delivery, ensuring high-quality outcomes and predictable timelines.

Durability & Energy Efficiency

The ETFE membrane and supporting structure combination provides long-term durability and weather resistance. Its energy-efficient performance lowers operational costs while maintaining a sustainable and comfortable indoor environment.
