Which GRC Manufacturer Behaviors Require Caution

In the field of UHPC/GRC/GRG/GRP materials, choosing a reliable manufacturer is key to ensuring project quality and safety. As industry demand grows, non-standard practices by some GRC manufacturers may plant hidden risks in projects. As an industry leader with 28 years of full-chain experience, Qinglong will analyze from a professional perspective which GRC manufacturer behaviors warrant caution, helping designers and owners avoid risks.

Warning 1: Cutting corners on materials and falsifying performance parameters. To reduce costs, some GRC manufacturers reduce glass fiber content or use inferior cement, resulting in insufficient flexural strength (quality GRC should have a flexural strength above 20MPa), greatly compromising durability. Such manufacturers often mislead clients by forging test reports or exaggerating performance parameters, which may eventually lead to safety issues such as component cracking and falling off. As a National High-Tech Enterprise, Qinglong always strictly controls material ratios, and all products pass authoritative third-party testing to ensure performance meets standards.

Warning 2: Weak design development capability, making it hard to realize complex forms. The advantage of GRC material lies in its high design freedom, but some manufacturers lack parametric design (such as Rhino, Grasshopper) and BIM application capabilities. When facing complex designs such as double-curved surfaces and openwork relief, they cannot accurately convert them into production drawings, causing significant deviation between the actual result and the design drawings. Qinglong has a provincial-level R&D center and a professional design team, and has successfully completed complex projects such as translucent concrete for the Nanjing East Road Century Plaza renovation, with full-process development capability from concept to realization.

Warning 3: Backward production processes and lack of quality control. GRC product production requires mature processes and a strict quality control system. Some manufacturers use backward processes such as manual casting and crude curing conditions, resulting in poor surface flatness and uneven strength. Worse still, some lack quality traceability systems, making it impossible to locate the cause when problems arise. Qinglong has established a 600,000-square-meter standardized production base, introducing automated production lines and RFID chip traceability technology, keeping the entire process from raw materials to finished products under control to ensure stable product quality.

Warning 4: Unprofessional installation services with prominent safety hazards. GRC component installation requires professional technology and experience. Some manufacturers neglect the installation stage, adopting non-standard practices such as simple anchoring and lacking 3D laser scanning positioning, which may lead to risks of falling from heights. Qinglong holds a Grade II professional contracting qualification for building curtain wall engineering. Its installation team adopts modular installation techniques to ensure “zero-error” joining, and has provided safe and reliable installation services for thousands of projects nationwide.

Warning 5: Empty after-sales maintenance promises and disconnected service. Some GRC manufacturers stop providing maintenance services once projects are delivered, making it difficult for owners to obtain timely support when problems such as component damage and fading occur. Qinglong always honors its commitment of being “meticulous and striving for excellence,” and has established a comprehensive after-sales maintenance system, providing customers with long-term technical support and eliminating worries.

When choosing a GRC manufacturer, you need to comprehensively evaluate its material quality, design capability, production process, installation service, and after-sales guarantee. As a member of the International GRC Association and a participant in drafting the Technical Standard for Glass Fiber Reinforced Cement (GRC) Building Applications, Qinglong has focused on the innovation and application of UHPC/GRC/GRG/GRP materials for 28 years, safeguarding projects with full-chain service capability. Owners and designers are advised to visit the manufacturer's production base on-site and review past project cases before cooperating, choosing a GRC manufacturer with genuine strength to jointly create quality architectural works.
