How to Avoid Buying GRC Products That Cut Corners?

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings thanks to its lightweight, high-strength, and richly formable characteristics. However, some manufacturers on the market cut corners in pursuit of short-term gains, resulting in quality problems such as cracking and spalling in GRC products, which not only affect building safety but also cause huge losses to project owners. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will explain from a professional perspective how to avoid the pitfalls of corner-cutting and select high-quality GRC products.

### I. Spotting Corner-Cutting: Core Quality Risks in GRC Products

GRC products with corner-cutting often involve "tampering" in three areas: material mix ratio, production process, and quality testing. First is insufficient glass fiber content—some manufacturers reduce the standard-required fiber content of 5%-8% to below 3%, directly causing the product's flexural strength to plummet from above 20MPa to below 10MPa, severely compromising structural stability. Second is the substitution of cement-based materials—using ordinary Portland cement instead of high-strength low-alkali cement, which cuts costs but greatly shortens product lifespan and easily leads to efflorescence and cracking in humid environments. Finally is the simplification of production processes—omitting steam curing or shortening curing time, so products leave the factory before reaching the required strength, planting hidden safety hazards.

### II. Three Tips to Distinguish Genuine from Fake: Criteria for Selecting a Professional GRC Manufacturer

**1. Verify Qualifications and Production Strength** When selecting a GRC manufacturer, focus on whether it holds National High-Tech Enterprise certification, whether it has participated in drafting industry standards (e.g., Qinglong Group participated in drafting the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) JGJ/T423-2018), and the scale of its production bases. Qinglong's production base in Nanning, Guangxi has an annual capacity of 600,000 square meters, equipped with fully automated production lines and a strict quality control system, ensuring product quality at the source.

**2. Verify Material Performance and Test Reports** Require the manufacturer to provide physical performance test reports issued by authoritative institutions, focusing on key indicators such as flexural strength, elastic modulus, and frost resistance. High-quality GRC products should have a flexural strength of ≥15MPa and pass 200 freeze-thaw cycle tests without cracking. Qinglong's GRC products have not only passed the Guangdong Provincial Science and Technology Achievement Appraisal but have also won multiple Science and Technology Progress Awards, with performance parameters far exceeding industry standards.

**3. Examine Project Cases and Full-Chain Service Capability** Manufacturers that cut corners often lack large-project experience, while professional manufacturers such as Qinglong have successfully undertaken landmark projects including the Dongguan Women and Children's Activity Center and Century Plaza on Nanjing East Road, and can provide full-process services from detailed design and BIM modeling to construction installation and after-sales maintenance. For example, in the Nanjing East Road project, Qinglong achieved a perfect combination of translucent concrete and GRC through parametric design, demonstrating strong technical implementation capability.

### III. Long-Term Assurance: Choose a GRC Supplier Offering "Full Life-Cycle" Services

The value of high-quality GRC products lies not only in their factory quality but also in their stability during long-term use. Qinglong Group has established a comprehensive after-sales maintenance system, ensuring that GRC components remain safe and reliable throughout the building's full life cycle through services such as regular inspections and material aging monitoring. Meanwhile, as a member of the International GRC Association, Qinglong has always honored its commitment of "meticulousness and excellence," integrating the values of integrity and perseverance into the entire product chain to provide designers and owners with GRC solutions that combine aesthetics and safety.

The quality of architectural decoration determines the success or failure of a project. When selecting GRC products, never ignore long-term risks for the sake of short-term costs. Only by verifying qualifications and strength, validating performance data, and examining project cases can you avoid the pitfalls of corner-cutting and partner with professional manufacturers like Qinglong to bring true safety and beauty to buildings.
