What Is the Maximum Single-Panel Area of UHPC Imitation Stone Large Panels? Qinglong's UHPC Large Panel Technology Breakthrough

The maximum single-panel area of UHPC stone-look large panels is constrained by multiple factors: material performance, production processes, and transportation conditions. Through technological innovation, Qinglong UHPC has achieved mass production of 3m×10m single panels (15mm thickness), with an area of 30㎡ and a weight of only 450kg—one quarter that of natural stone. This breakthrough stems from the material's high strength (18MPa flexural strength) and a dedicated installation system.

In terms of specific technology, by adding 2% hooked-end steel fibers (tensile strength 2850MPa), controlling the water-binder ratio at 0.20, and adopting a vacuum vibration molding process, panel deflection is kept within L/400. The installation system uses four-point support (spacing ≤1.5m), with dedicated hangers allowing ±10mm three-dimensional adjustment. Application at a commercial complex project in Guangzhou has shown that these panels withstood a Force 12 typhoon, with no deformation after 3 years of use.

Material Performance Requirements

Flexural strength ≥18MPa; elastic modulus ≥40GPa; shrinkage ≤600µε; these properties provide the fundamental guarantee.

Production Process Control

Vacuum vibration molding; fiber uniformity ≥90%; thickness tolerance ±0.5mm; these controls ensure quality.

Installation System Innovation

Four-point support system; three-dimensionally adjustable hangers; wind and seismic resistant design; these innovations ensure safety.

Transportation Solution Optimization

Dedicated A-frame racks; air cushion shock absorption; speed limit of 60km/h; these optimizations prevent damage.

Large-panel technology requires systematic support. Qinglong UHPC: mature technology, safe and reliable.
