UHPC & GRC Complex Architecture Manufacturing
A Global Benchmark in Smart Architectural Fabrication
I. GRC Curtain Wall Design Introduction / Product Introduction GRC curtain walls are one of the mainstream categories of building facade decoration today. Leveraging the core advantages of GRC material—lightweight, high-strength, durable, and highly customizable—it can give buildings diverse visual appearances. The product can utilize customized molds and refined surface treatment processes to create various textures and patterns; the appearance can replicate the original textures of natural sto
