What Are the Production Processes of GRC Manufacturers? A Complete Analysis of GRC Component Production Workflow and Technical Key Points

In the field of architectural decoration, GRC (Glass Fibre Reinforced Concrete) has become an important material for shaping architectural aesthetics thanks to its lightweight, high strength and flexible formability. As a GRC manufacturer with 28 years of industry experience, Qinglong will analyse the production process of GRC components from a professional perspective, revealing the key technical points across the entire process from design to finished product, providing an in-depth reference for designers and owners.

GRC Manufacturer Production Process Analysis: Precision Control from Raw Materials to Finished Products

The creation of high-quality GRC components begins with scientific raw material proportions and a rigorous production process. Qinglong GRC manufacturer uses high-grade sulphoaluminate cement, alkali-resistant glass fibres, selected aggregates and modified additives, with precise metering to ensure stable material performance. During the mixing stage, a low-speed horizontal-axis mixer is used to achieve uniform fibre dispersion and avoid clumping—this is the core prerequisite for guaranteeing a GRC flexural strength above 20MPa.

Mould making is a critical step in GRC production. Relying on its design development team, Qinglong uses BIM technology and CNC engraving to transform designers' creative ideas into high-precision moulds. Whether it is the classical European texture of Roman columns or the double-curved forms of modern architecture, mould precision directly determines the detail expressiveness of the finished product. For complex special-shaped components, GRP moulds and silicone replica-moulding technology are used to ensure shape fidelity of over 99%.

GRC Component Manufacturing Process: The Balancing Art of Standardisation and Customisation

The production process of Qinglong GRC manufacturer integrates standardised management with customised services. In the spray-up stage, a process combining mechanical spraying and manual finishing is adopted, controlling the fibre content between 4-5%, which ensures structural strength while meeting surface flatness requirements. For oversized components (such as exterior wall cladding panels longer than 6 metres), composite reinforcement with built-in steel bar frames and fibre mesh achieves the unity of lightweight design and safety.

The curing process directly affects the durability of GRC components. Qinglong combines steam curing with natural curing, promoting cement hydration reactions in a constant temperature and humidity environment to ensure the 28-day compressive strength meets standards. For projects in cold regions, freeze-thaw resistant additives are specially added; the material shows no cracks after 200 freeze-thaw cycles at -20°C, fully verifying its weather resistance.

Key Technical Points and Quality Control: Qinglong Manufacturer's 28 Years of Accumulated Experience

As an enterprise that participated in drafting the Technical Standard for Building Application of Glass Fibre Reinforced Cement (GRC), Qinglong strictly implements three key technical points in production: first, fibre dispersion uniformity control, monitored in real time through an online inspection system; second, precise adjustment of the water-cement ratio to ensure component compactness; third, surface treatment processes, using high-pressure water washing and sealant spraying to enhance waterproofing and texture.

The quality traceability system is the core competitiveness of Qinglong GRC manufacturer. Each batch of components is embedded with an RFID chip recording the production batch, material proportions, curing parameters and other information, achieving full lifecycle traceability. Meanwhile, a three-level quality inspection system has been established: from raw material entry to finished product dispatch, more than 20 indicator tests—including flexural strength, impact resistance and ageing resistance—ensure a 100% pass rate for delivered products.

From the curved curtain wall of Guangzhou Opera House to the light-transmitting components of Century Plaza on Nanjing East Road, Qinglong GRC manufacturer has perfectly integrated process precision with artistic expression through 28 years of full-chain service experience. Choosing a professional GRC manufacturer is not just choosing a material, but choosing a full-process solution from design development to after-sales maintenance, making the realisation of architectural creativity more efficient and more reliable.
