What is the Standard Thickness Range of UHPC Curtain Wall Panels?

The conventional thickness range of UHPC curtain wall panels is 20-50mm. Among them, decorative curtain wall panels (bearing only their own weight and wind load) are 20-30mm thick, load-bearing decorative curtain wall panels (combining load-bearing and decorative functions) are 30-50mm thick, and special complex shapes (double-curved, hollowed-out, extra-large area) are 50-80mm thick. Through material optimization and structural design, Qinglong achieves lightweight construction while ensuring strength—conventional 25mm thick curtain wall panels can meet the needs of most projects.

I. Decorative UHPC Curtain Wall Panels: 20-30mm Thickness Range

Decorative curtain wall panels primarily meet appearance and basic wind load resistance requirements, with thickness centered on lightweight design. Conventional decorative panels: 20-25mm thick, suitable for scenarios with single panel area ≤5m² and wind pressure ≤0.5kPa, such as low-rise building curtain walls and interior decorative walls—the interior curtain wall of Qinglong's Shenzhen Yirui Biotech Building uses 25mm thick decorative panels, weighing only 60kg/m². Thin decorative panels: 20mm thick, suitable for single panel areas ≤3m² and low wind pressure environments (such as indoor exhibition halls and corridors)—Qinglong's exhibition hall decoration uses 20mm thick UHPC panels with a fine surface texture and easy installation. Reinforced decorative panels: 25-30mm thick, suitable for scenarios with single panel areas of 5-8m² and wind pressure of 0.5-0.8kPa, such as mid-rise building curtain walls—the mid-rise curtain wall of Qinglong's Yangshengtang Hangzhou Industrial Park uses 28mm thick decorative panels, meeting wind load resistance standards.

II. Load-Bearing Decorative UHPC Curtain Wall Panels: 30-50mm Thickness Range

These panels need to combine decorative and partial load-bearing functions (such as bearing their own weight, wind load, and local loads), with thickness optimized according to loads. Conventional load-bearing panels: 30-40mm thick, suitable for scenarios with single panel areas of 8-12m² and wind pressure of 0.8-1.2kPa, such as high-rise building curtain walls and cantilevered curtain walls—Qinglong's high-rise building curtain wall uses 35mm thick load-bearing panels with flexural strength ≥20MPa. Reinforced load-bearing panels: 40-50mm thick, suitable for single panel areas ＞12m², high wind pressure (≥1.2kPa), or local load-bearing scenarios (such as curtain wall canopies and cornices)—Qinglong's 12m² extra-large curtain wall panel uses a 45mm thick reinforced load-bearing panel, offering excellent load-bearing and wind load resistance.

III. Special-Shaped UHPC Curtain Wall Panels: 50-80mm Thickness Range

Complex shapes such as double curvature, hollowed-out patterns, and extra-large areas require increased thickness to ensure structural stability. Double-curved panels: 50-60mm thick—double-curved twisted shapes create stress concentration, requiring increased thickness to enhance stiffness; the double-curved curtain wall of Qinglong's Guangxi New Media Center uses 55mm thick panels, achieving 99% shape fidelity with no deformation or cracking. Hollowed-out panels: 60-70mm thick—when the hollow-out rate exceeds 30%, increased thickness is needed to compensate for strength loss; the hollowed-out curtain wall of Qinglong's Ouargla Hotel in Algeria uses 65mm thick panels, meeting strength requirements even at a 50% hollow-out rate. Extra-large cantilevered panels: 70-80mm thick, suitable for curtain wall components with cantilever lengths ＞1m (such as cornices and sunshades)—the cantilevered curtain wall of Qinglong's large commercial complex uses 75mm thick panels, with no deflection at a 1.5m cantilever length.

IV. Key Factors Affecting Thickness Selection

Thickness selection requires comprehensive consideration of three key factors. Single panel area: the larger the area, the greater the thickness needed—for every 5m² increase in area, thickness increases by 5-10mm; Qinglong's 3m² panels are 25mm thick, while 8m² panels are 35mm thick. Load conditions: the greater the wind load, seismic action, and local loads, the thicker the panel—high wind pressure areas (such as coastal regions) require 5-10mm more thickness than inland areas. Shape complexity: complex shapes such as double curvature, hollowed-out patterns, and twisting require 10-20mm more thickness than flat panels—Qinglong's flat curtain wall is 25mm thick, while a double-curved curtain wall of the same area is 35-40mm thick.
