What Is the Typical Thickness of GRC Panels for Curtain Walls? — Panel Thickness Design Principles and Engineering Application Guide

The thickness design of GRC panels for curtain walls must comprehensively consider multiple factors such as strength requirements, stiffness needs, economy, and construction conditions, and be determined through scientific calculation and optimization. Based on 28 years of engineering practice, Qinglong Group holds that the thickness of high-quality GRC curtain wall panels typically falls within the 15-25mm range, with appropriate thickening or thinning allowed at special locations. This thickness design both meets structural requirements and achieves optimal economy.

Strength requirements are the primary factor in determining thickness. The required thickness is calculated based on wind load and panel span. In its Shenzhen project, Qinglong Group optimized panel thickness through finite element analysis, controlling material usage while meeting strength requirements. Stiffness needs affect panel thickness selection to avoid excessive deformation. For economy, thickness is minimized as much as possible on the premise of safety to save costs. By comprehensively balancing these factors, the optimal panel thickness is determined.

Thickness is adjusted at special locations. Areas of stress concentration such as corners and edges are appropriately thickened to enhance safety. Thickness is increased for large panel spans to avoid vibration. Through differentiated thickness design, Qinglong Group achieves the optimal balance between safety and economy. Scientific panel thickness design provides assurance for the reliable use of GRC curtain walls.
