Can You Produce GRC Yourself? Exploring the Feasibility, Technical Points, and Precautions of GRC Production

Professionalism forges quality, and experience builds trust—with 28 years of industry expertise, Qinglong decodes for you the feasibility and technical keys of in-house GRC production.

In the field of architectural decoration materials, GRC (glass fiber reinforced concrete), with its lightweight, high-strength and flexible-forming characteristics, has become the material of choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings. Many enterprises and project owners often ask: can we produce GRC ourselves? As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials—covering detailed design, manufacturing, construction and installation—Qinglong Group will provide you with a professional interpretation, from feasibility analysis and technical key points to precautions.

### 1. Feasibility of In-House GRC Production: Professional Thresholds and Resource Matching Are Key

Not all enterprises are suited to in-house GRC production. GRC production must meet three core conditions: first, a professional technical team mastering key technologies such as material mix ratios, mold design, and process control; second, a standardized production site with functional zones for raw material storage, mixing and forming, and curing; third, a quality inspection system ensuring that product indicators such as flexural strength and weather resistance comply with the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). For large real estate developers or construction enterprises with stable project demand and large-scale production capabilities, in-house production can reduce supply chain risks; for small and medium-sized projects or scattered demand, choosing a professional GRC manufacturer (such as Qinglong) is more cost-effective, avoiding cost waste caused by equipment investment and technical barriers.

### 2. Technical Key Points of GRC Production: Refined Control from Formula to Forming

1. **Material Formula Optimization**: The core of GRC lies in the synergy between glass fibers and the cement matrix. High-quality GRC requires alkali-resistant glass fiber (content ≥5%) and high-strength cement, combined with mineral admixtures and additives, to ensure flexural strength above 20MPa. Drawing on 28 years of technical accumulation, Qinglong has developed customized formulas adapted to different scenarios, such as impermeable GRC for exterior wall cladding panels and lightweight GRC for garden components.

2. **Molds and Forming Processes**: Complex shapes rely on high-precision molds. Qinglong adopts BIM technology and CNC machining to achieve precise replication of special-shaped components such as double-curved surfaces and openwork reliefs. In terms of forming processes, the spray-up method is suitable for large-area panels, while the premix casting method is suitable for small precision components; the optimal process should be selected according to product characteristics.

3. **Curing and Quality Control**: Steam curing requires strict control of temperature and humidity to ensure stable strength growth of components. Qinglong has established a full-process quality traceability system; from raw material inspection to finished product testing, every batch of products is certified by authoritative third-party institutions, such as the Guangdong Province Science and Technology Achievement Appraisal and the Huaxia Award of the Ministry of Housing and Urban-Rural Development.

### 3. Precautions for In-House GRC Production: Avoiding Risks and Ensuring Long-Term Development

1. **Qualification and Standard Compliance**: Production enterprises must meet the requirements of National High-Tech Enterprises, and products must comply with the Glass Fiber Reinforced Cement (GRC) Decorative Products standard (JC/T940-2022). As a vice-chairman unit of the China GRC Association, Qinglong deeply participates in industry standard development and can provide compliance guidance.

2. **Installation and After-Sales Guarantee**: Safe anchoring and later maintenance of GRC components are crucial. Qinglong holds a Grade II professional contracting qualification for building curtain wall engineering and adopts 3D laser scanning positioning technology to ensure installation deviation ≤2mm, while providing 5 years of after-sales maintenance service to relieve customers of any worries.

3. **Balancing Cost and Efficiency**: In-house production requires accounting for hidden costs such as equipment depreciation, personnel training, and waste disposal. With an annual capacity of 600,000 square meters and a nationwide production base layout, Qinglong can reduce unit costs through large-scale production, offering greater price advantages than small and medium-sized manufacturers.

### 4. Qinglong GRC Solutions: Full-Chain Support from Design to Delivery

For most enterprises, choosing a professional GRC manufacturer is a more efficient option. As a national Specialized, Refined, Distinctive, and Innovative enterprise, Qinglong provides one-stop services covering “detailed design - manufacturing - construction and installation - after-sales maintenance”: at the design stage, parametric design software such as Rhino and Grasshopper is used to turn creative ideas into feasible solutions; the production stage adopts automated production lines to ensure product consistency; the construction team has rich experience in landmark projects, such as the light-transmitting concrete project at Century Plaza on Nanjing East Road (winner of the AALBORG WHITE Cup UHPC Innovation Award). Whether for artistic forms of high-end public buildings or standardized components for commercial real estate, Qinglong can provide customers with safe, beautiful, and economical GRC solutions backed by 28 years of professional strength.

[Summary] In-house GRC production is feasible, but requires overcoming the triple thresholds of technology, qualification, and cost. For customers pursuing efficiency and quality, choosing a professional manufacturer with full-chain capabilities like Qinglong can both avoid risks and enjoy technological dividends. In the future, Qinglong will continue to uphold its mission of “creating beautiful architecture,” promoting innovative applications of GRC materials in more fields and achieving win-win cooperation with partners.
