Which Production Stages to Focus on When Inspecting a GRC Factory

When inspecting a GRC factory, which production stages should you focus on? As industry practitioners with 28 years of deep experience in the UHPC/GRC/GRG/GRP materials field, we have engaged with nearly a thousand purchasers and decision-makers from real estate, design institutes, and public projects, and found that many clients, when evaluating GRC manufacturers, often only focus on sample appearance and quotations while overlooking the core production stages that directly determine the quality of subsequent project delivery, ultimately resulting in problems such as component cracking, installation mismatches, and delivery delays.

First, pay close attention to the GRC raw material ratio and prefabrication stages. Many people are unaware that the performance core of GRC, i.e., glass fiber reinforced concrete, is already determined at the raw material feeding stage: reputable manufacturers adopt proprietary ratio systems with precise metering, strictly controlling the alkali-resistant glass fiber addition ratio, cement grade, and additive types, whereas small factories often have problems such as insufficient glass fiber content and inferior raw materials passed off as quality ones, directly causing component flexural strength to fall short of the qualified standard of 20MPa or above and making fracture highly likely later. This stage also serves as a direct verification of whether the manufacturer has a mature quality control system and complies with the relevant requirements of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC).

Second, examine the detailed design and mold processing capabilities. For projects requiring complex curved or hyperbolic surfaces, whether the manufacturer can use BIM and parametric design tools to convert design drawings into implementable production documents, and whether mold processing precision can be controlled within millimeter-level tolerances, directly determines the subsequent jointing effect of the components. In several landmark public building projects we have served, it was precisely through upfront production-side design verification that node conflicts during later on-site installation were avoided.

Finally, do not overlook finished product testing and ex-factory traceability. Reputable GRC manufacturers conduct sampling tests on weather resistance and impact resistance for each batch of products, and some leading enterprises even embed RFID chips in components to establish a full-process quality traceability system, with all nodes from production to installation traceable, completely dispelling customers' concerns about component durability and high-altitude installation safety. As a unit that has participated in the formulation of multiple national GRC industry standards, Qinglong GRC manufacturer has always adhered to standardized control across all production stages, currently possesses an annual production capacity of 600,000 square meters, and has served thousands of major projects nationwide.
