ETFE+PTFE Double Membrane Structure System Empowers Zhengzhou Zhongyuan High-Speed Railway Port Digital Expo City

Wanhao’s material selection demonstrates meticulous engineering insight: The ETFE air cushion membranes, with over 90% light transmittance, flood interiors with natural illumination, fostering bright, inviting environments. Their high-strength yet lightweight properties reduce structural loading by 30%, while integrated thermal insulation layers achieve a U-value of ≤3.0 W/(m²·K), balancing energy efficiency with occupant comfort. The PTFE membranes, formulated with fluoropolymer coatings, offer superior corrosion resistance and a 25+ year service life, requiring minimal maintenance due to their hydrophobic surfaces that repel dust and debris. Together, these materials create a dynamic synergy—ETFE’s translucency contrasting with PTFE’s durability—to harmonize architectural elegance with functional resilience.

Executing such a large-scale project—featuring 100,000+ tons of steel, 30,000 m² of ETFE roofing, and 100,000 m² of PTFE cladding—required Wanhao’s unmatched technical prowess. Our team employed advanced finite-element analysis during design, ensuring optimal load distribution across membrane surfaces, while precision installation utilized hydraulic tensioning systems to achieve uniform pre-stress within a 5% tolerance. BIM-driven modeling guided every phase, from parametric cutting of membrane panels to millimeter-accurate node connections, transforming engineering blueprints into a structurally optimized reality.

This landmark project stands as a testament to Wanhao’s leadership in membrane structureinnovation—from material science expertise to full-cycle project delivery. By pushing the boundaries of form and function, we’ve created a space that not only redefines commercial architecture but also sets new industry standards for sustainability and technical excellence. As we look to the future, the Zhengzhou expo city serves as a launchpad for our ongoing mission: to pioneer membrane solutions that blend structural integrity, environmental responsibility, and timeless design, shaping the skylines of tomorrow with every project we undertake.
