Advantages and Application Value of GRC in Curtain Wall Engineering

### When Architectural Aesthetics Meet Material Technology: Six Core Values of GRC Empowering Curtain Wall Engineering

In contemporary architectural design, curtain walls are not only the building's “outer garment” but also an important vehicle for designers to express creativity and realize aesthetic visions. With the iterative advancement of material technology, glass fiber reinforced concrete (GRC), with its unique performance advantages, is becoming a preferred material in the field of curtain wall engineering. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain service capabilities to deeply integrate the technical characteristics of GRC with architectural art, creating curtain wall systems that combine functionality and visual appeal for over a thousand landmark projects.

#### I. GRC Curtain Wall Materials: Redefining the Possibilities of the Building Skin

GRC curtain wall materials are made with alkali-resistant glass fiber as the reinforcing material and cement mortar as the base material, produced through processes such as spraying and pre-casting, combining the strength of concrete with the toughness of composite materials. Compared with traditional stone curtain walls, GRC weighs only 1/4 as much, greatly reducing structural load on the building; compared with metal curtain walls, its surface can achieve diverse textures such as faux stone and faux wood grain, with a greater cost advantage. In a commercial complex project in Shenzhen, the Qinglong team used GRC materials to realize a curved curtain wall with a 12-meter span, and millimeter-level precision jointing technology perfectly brought the flowing lines of the design drawings to life—a vivid demonstration of GRC's “boundless freedom of form.”

#### II. Analysis of GRC Curtain Wall Advantages from a Full Life-Cycle Perspective

Considering full life-cycle project costs, the comprehensive value of GRC curtain walls is particularly outstanding. In the detailed design phase, Qinglong relies on BIM technology and parametric design capabilities to quickly respond to complex curtain wall form requirements, reducing time costs caused by design iterations; the production process adopts automated assembly lines with an annual capacity of 600,000 square meters, ensuring on-time delivery of large projects; during installation, modular construction and 3D laser positioning technology increase on-site work efficiency by 40%. Even more noteworthy, GRC materials offer weather resistance of over 50 years, and combined with the professional maintenance services provided by Qinglong, significantly reduce later-stage maintenance investment. In a provincial grand theater project, the GRC curtain wall system maintained its original surface color and structural performance after 10 years of exposure to wind and rain, confirming the material's long-term stability.

#### III. Synergistic Application of GRC with UHPC/GRG/GRP: Creating Composite Curtain Wall Solutions

A single material can hardly meet the needs of all curtain wall scenarios. Qinglong innovatively combines GRC with UHPC, GRG, GRP, and other materials in scientific formulations to form multifunctional composite curtain wall systems. For example, in super high-rise projects, composite panels of “GRC decorative layer + UHPC structural layer” meet wind pressure resistance requirements while achieving complex architectural textures; in interior curtain wall scenarios, the acoustic properties of GRG materials are incorporated to create integrated walls with both decorative and sound-absorbing functions. This “material combination” strategy enabled Qinglong to successfully solve the triple challenges of load-bearing, sound insulation, and fire protection for large-span curtain walls in a cultural center project in Guangzhou, earning high recognition from the owner and the design team.

#### IV. Quality Commitment of an Industry Standard Setter: From Technological Innovation to Engineering Practice

As a contributing unit to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong has always controlled product quality with requirements exceeding industry standards. By introducing internationally advanced material testing equipment, every batch of GRC products undergoes 28 indicator tests covering flexural strength, frost resistance, alkali resistance, and more. In the Nanjing East Road Century Plaza renovation project, Qinglong's self-developed translucent GRC curtain wall panels combine traditional materials with modern lighting effect technology, presenting a fine stone texture during the day and creating dreamlike light and shadow effects through built-in light sources at night. The project won the Silver Award in the first UHPC Building Engineering Innovation Awards, becoming a model of innovative GRC material application.

From the eave lines of classical architecture to the artistic skin of modern curtain walls, GRC materials are reshaping the visual language and technical boundaries of buildings. Supported by 28 years of full-chain experience, Qinglong Group deeply integrates material technology with engineering practice, not only providing designers with a “vehicle of inspiration” to realize creativity, but also building curtain wall systems with both aesthetic and economic value for owners. Today, as green building and sustainable development become industry trends, GRC curtain walls, with their lightweight, renewable, and long-life characteristics, will undoubtedly occupy an even more important position in the future building market.
