Can You Produce GRC Yourself? Feasibility, Technical Requirements and Practical Guide to 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 preferred material for landmark buildings and high-end projects. However, many companies and project owners face a key question: can they produce GRC themselves? As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group will give you an in-depth analysis of the core essentials of independent GRC production from three dimensions: feasibility, technical thresholds and practical pathways.

The Feasibility of Independent GRC Production: Opportunities and Challenges Coexist

From a material properties perspective, GRC is a composite of cement, glass fiber, aggregates and other base materials, and the raw materials are relatively easy to obtain, which makes independent production theoretically feasible. Especially for large construction companies or real estate developers with an annual demand of more than 10,000 square meters, building an in-house production line can significantly reduce procurement costs and shorten the supply chain cycle. However, it should be noted that GRC production is not simply mixing materials; its core lies in mix ratio optimization and process control — taking the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018), which Qinglong participated in drafting, as an example, qualified GRC must meet stringent indicators such as flexural strength ≥12MPa and impact strength ≥10kJ/m²; without professional technical accumulation, quality problems such as cracking and efflorescence are very likely to occur.

Technical Requirements for GRC Production: Full-Process Control from Laboratory to Production Line

Independent GRC production requires crossing three major technical thresholds: first is the development of the formulation system, which requires adjusting the glass fiber content (usually 4-6%), cement grade and additive ratios according to project requirements to balance strength and plasticity; second is the choice of forming process — the spraying method, premix method or compression molding method each has its own applicable scenarios; for example, double-curved components require the spraying + vacuum degassing process, while standardized profiles are better suited to premix casting; last is the quality inspection system, which requires professional testing equipment for flexural strength, freeze-thaw resistance, etc., to ensure that products comply with the GRC Decorative Products (JC/T940-2022) standard. Qinglong's production base in Nanning, Guangxi, equipped with production lines of an annual capacity of 600,000 square meters, achieves quality assurance from millimeter-level precision to century-long durability through full-process control of "formulation development – mold design – CNC machining – non-destructive testing".

Practical Guide: Path Selection Between Small-to-Medium Scale and Large-Scale Production

For companies trying GRC production for the first time, a phased approach is recommended: in the initial stage, a "technical cooperation + entrusted processing" model can be adopted, building a joint laboratory with manufacturers holding national Specialized and Innovative qualifications such as Qinglong and sharing formulation and process data; in the intermediate stage, automated mixing and cutting equipment can be gradually introduced, focusing on the production of standardized components; large-scale production requires investment in BIM parametric design systems and intelligent curing kilns to achieve digital management from design to installation. It is worth noting that the hidden costs of GRC production are often overlooked, including mold wear (complex-shaped molds last only 50-100 uses), environmental treatment (dust and wastewater purification) and installation technical support. As a member of the International GRC Association, Qinglong can provide "turnkey" services from detailed design to after-sales maintenance, helping companies avoid technical risks.

Independent GRC production is a "double-edged sword": it can bring cost advantages and customization flexibility, but it also tests a company's technical reserves, financial strength and management capabilities. For companies pursuing short-term project benefits, choosing a supplier with full-chain service capabilities (such as Qinglong) better ensures project quality and delivery efficiency; for companies with a long-term presence in the architectural decoration field, they can rely on industry standards and technical cooperation to gradually build an independent production system. Whichever path is chosen, only by putting technology at the core and relying on standards can aesthetic value and engineering safety be unified in GRC applications.
