Key Stages and Technical Analysis of GRC Manufacturers' Production Processes

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) has become the "sculpting magician" behind numerous landmark buildings thanks to its lightweight yet high-strength properties and flexible shaping capabilities. As a Qinglong GRC manufacturer with 28 years of industry experience, we understand that every step of the production process directly determines the quality and expressiveness of the final product. This article provides an in-depth analysis of the key technical processes in GRC manufacturing, revealing how Qinglong delivers customized solutions that combine aesthetic value with structural safety through full-chain process control.

The Core of GRC Manufacturer Production Processes: Material Formulation and Fiber Dispersion Technology

The performance of GRC material is rooted in a scientific formulation system. Qinglong GRC manufacturer uses high-grade Portland cement, selected quartz sand, and special additives, with an exclusive mix ratio developed through 28 years of technical accumulation, ensuring the compressive strength of the matrix material remains stable above 60MPa. The dispersion process of glass fibers is another major technical challenge—Qinglong has imported German mixing equipment and applies three-dimensional spiral mixing technology to achieve uniform distribution of glass fibers (12-25mm in length) within the cement matrix, precisely controlling fiber content at 3-5% and raising flexural strength to over 20MPa, far exceeding the industry average. This process not only solves the fiber clumping problem caused by traditional manual mixing but also provides reliable structural support for complex-shaped components.

Mold Development and Forming Processes: The Core of a GRC Manufacturer's Customization Capabilities

As a professional GRC manufacturer, Qinglong knows well that "the mold is the soul of shaping." For different project requirements, we employ multiple types of mold systems, including wooden molds, steel molds, and GRP molds: for standardized components such as European classical moldings, high-precision steel molds are used to ensure dimensional consistency; for irregular components such as the hyperbolic curtain walls of grand theaters, three-dimensional scanning and reverse modeling technology, combined with epoxy resin molds, achieves millimeter-level precision replication. In the forming process, Qinglong innovatively adopts a combined "spraying + premixing" process—first, fibers and mortar are tightly bonded through high-pressure spraying, then premixed material is cast to fill complex cavities, ensuring both fine surface quality of components and enhanced structural density. This process successfully achieved the perfect composite of translucent concrete and GRC in the Nanjing Road Century Plaza renovation project, winning an industry innovation award.

Curing Process and Quality Control: Key Measures for GRC Manufacturers to Ensure Durability

The durability of GRC components largely depends on the curing process. Qinglong GRC manufacturer has established a constant temperature and humidity curing kiln system, using 72-hour steam curing (temperature controlled at 60±5℃, humidity ≥90%) to accelerate the cement hydration reaction, allowing components to quickly reach early strength targets. In the later stage, a combination of natural curing and spray curing is used to ensure the strength at 28 days of age meets design requirements. In terms of quality control, every batch of products must pass 12 testing indicators, including flexural strength, frost resistance, and carbonation depth, and RFID chips are embedded in key components to enable full lifecycle traceability. This stringent quality control system has enabled Qinglong GRC products to withstand extreme climates in overseas projects such as the Petronas Twin Towers in Malaysia and the Sydney Opera House in Australia.

Full-Chain Service Capability: Closed-Loop Assurance from Design to Installation by GRC Manufacturers

An excellent GRC manufacturer is not only a producer but also a solution provider. Qinglong integrates full-chain resources covering detailed design, production and manufacturing, construction and installation, and after-sales maintenance: in the design phase, BIM technology is used for parametric modeling and structural force analysis; in production, intelligent production lines with an annual capacity of 600,000 square meters are employed; during installation, three-dimensional laser scanning positioning technology achieves "zero-error" splicing; and after-sales support comes with a maintenance commitment of up to 15 years. This "one-stop" service model was fully demonstrated in the Dongguan Women and Children's Activity Center project, where the complex hyperbolic GRC curtain wall system achieved a perfect unity of design effect and engineering quality, winning the first GRC Construction Engineering Innovation Award.

As a national high-tech enterprise and a participant in setting GRC industry standards, Qinglong consistently refines every production step with a "meticulous and excellence-driven" attitude. From continuous optimization of material formulations to innovative breakthroughs in forming processes, and from strict quality control to full-cycle service assurance, Qinglong GRC manufacturer is driving the continuous expansion of GRC material applications in the field of architectural decoration through deep technical expertise. Choosing a professional GRC manufacturer means not only choosing quality products, but also choosing a long-term commitment to architectural aesthetics and structural safety.
