Typical Thickness Range of UHPC Curtain Wall Panels: Qinglong's Selection Reference Based on 1,000 Projects

The thickness of UHPC curtain wall panels directly affects mechanical performance, installation efficiency, and project cost. Proper thickness selection is key to balancing design effects and practical value. As a core supplier of UHPC curtain wall panels, Qinglong Group has completed over 600,000 square meters of projects over 28 years and has summarized standard thickness ranges and selection logic covering different scenarios.

1. Standard Thicknesses: Core Ranges and Application Scenarios

The standard thickness range for UHPC curtain wall panels is 15-60mm, subdivided into three ranges based on functional requirements and installation conditions: non-load-bearing decorative panels at 15-30mm, integrated load-bearing decorative panels at 30-45mm, and large-span or shaped panels at 45-60mm. This range aligns closely with mainstream international standards (16-100mm). Qinglong used 25mm-thick flat UHPC panels for the Yirui Biotechnology Building in Shenzhen and selected 50mm-thick perforated panels for the Ouargla Hotel in Algeria, achieving a perfect match between design and performance in both cases.

2. Thickness Selection: Four Key Factors????

1. Span Dimensions: For panel spans ≤1.5m, choose 15-25mm thickness; for spans of 1.5-3m, choose 25-40mm; for spans ＞3m, choose 40-60mm. Qinglong customized a 12㎡ oversized UHPC panel for the Century Plaza on Nanjing East Road at Shanghai New World, with a span of 3.5m and a thickness of 55mm, meeting mechanical requirements.

2. Load Conditions: Panels bearing only self-weight and wind loads should be 15-30mm thick; those subject to snow loads or local impact should be 30-45mm. The UHPC roof curtain wall panels at the Hainan International Convention and Exhibition Center are 42mm thick to withstand typhoon loads.

3. Design Complexity: Flat curtain wall panels are 15-25mm thick, while double-curved and perforated panels require an additional 5-15mm due to structural weakening. The double-curved UHPC curtain wall panels at the Guangxi New Media Center have a base thickness of 30mm, thickened to 40mm at perforated areas.

4. Functional Integration: Integrated panels combining thermal insulation and fire protection are 40-60mm thick, with built-in insulation layers or fire-resistant core materials. Qinglong customized an insulation-integrated UHPC curtain wall panel for a high-end hotel, 50mm thick, with insulation performance meeting Class A standards.

3. Selection Cases: Thickness Practices in Qinglong Landmark Projects

1. Commercial Complex: Dongzhu Shangdu Commercial City in Guangzhou uses 28mm-thick UHPC cladding panels that balance decorative effects with lightweight installation, weighing only 67kg/㎡ per panel to reduce building loads.

2. Cultural Landmark: The public art curtain wall panels at the Shanghai Astronomy Museum use a thickness of 35mm due to complex shapes and impact resistance requirements, achieving artistic forms while ensuring structural safety.

3. Industrial Buildings: The inclined UHPC panel curtain wall at the Yirui Biotechnology Building in Shenzhen has a span of 2.8m and a thickness of 32mm, with tested wind load resistance reaching 0.75kN/㎡, meeting industrial building requirements.

4. Overseas Projects: A commercial center in Saudi Arabia uses 30mm-thick UHPC curtain wall panels, selected with the local high-temperature climate in mind to balance heat resistance and cost-effectiveness.

Thickness selection for UHPC curtain wall panels requires comprehensive consideration of multiple factors. Leveraging its expertise from participating in formulating the 'Ultra-High Performance Concrete (UHPC) Exterior Wall Panels' standard, Qinglong provides precise thickness recommendations for each project. From load calculations to shape adaptation, and from functional integration to cost optimization, full-process technical support ensures scientifically sound thickness selection, delivering dual improvements in quality and efficiency.
