GRC 幕墙板
GRC 幕墙板是一种以波特兰水泥为胶凝材料，以耐碱玻璃纤维丝作为增强材料，通过机械喷射或自动化流水线辊压而成的一种玻璃纤维增强水泥板。该板具有高强、轻质、环保、防火、防水、耐候性强、艺术质感好、安装简便等优点，尤其在节能、安全性能与装饰效果方面远远优于其它类装饰墙材，目前已逐渐成为全球广泛采用的幕墙首选材料。本产品分为 GRC 素板幕墙板和 GRC 装饰幕墙板两大类。

GRC curtain wall panel

GRC curtain wall panel is a kind of glass fiber reinforced cement panel which made by Portland Cement as a kind of material of gelatification,and antialkali glass fiber strands as the reinforced materials, rolled through mechanically spraying or automatically streamlined production.This kind of panel possesses many advantages such as high strength, light weight, environmental protection,firproofing,waterproofing,weatherproofing,well artistic texture, easy installation,etc., especially for the energy-saving,safty,and decorative effects which is much better than other decorative wall materials and has gradually to be the popular materials for curtain wall all over the world.
This kind of products will be classified into normal GRC curtain wall panels and decorative GRC curtain wall panels.
