How to Judge if a UHPC Manufacturer's Mix Technology Is Advanced

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for many high-end construction projects thanks to its advantages such as lightweight high strength and flexible styling. However, different GRC manufacturers vary significantly in production processes, and these differences directly affect product quality, performance, and project implementation results. Qinglong Group, with 28 years of industry experience, will provide an in-depth analysis of the process differences and technical characteristics of various manufacturers from the dimensions of material formulation, molding process, and quality control, offering a professional reference for designers and owners.

The core of GRC production technology lies in the scientific basis and stability of material formulations. High-quality GRC manufacturers strictly select raw materials such as cement, glass fiber, and aggregates, improving product flexural strength (some companies can reach over 20MPa) and weather resistance through precise proportioning. For example, Qinglong uses high-purity rapid-hardening sulphoaluminate cement combined with alkali-resistant glass fiber, optimizing the ratio through repeated tests so that products maintain stable performance in environments from -40°C to 70°C. However, some small manufacturers, in order to reduce costs, may use ordinary Portland cement or low-alkali glass fiber, resulting in products that are prone to cracking and lack durability.

The molding process is key to determining the precision of GRC components and the ability to achieve complex shapes. Mainstream processes include spray-up molding, premix molding, and negative pressure molding. Qinglong adopts a combined "spray + vacuum assistance" process in the production of large hyperbolic components, using robotic arms to spray materials precisely, together with negative pressure equipment to remove air bubbles, ensuring component compactness reaches over 98%, with the minimum curvature radius controllable within 300mm. In contrast, traditional manual spraying processes are heavily dependent on operator experience and prone to problems such as uneven thickness and disordered fiber distribution, making it difficult to meet the refined requirements of landmark buildings.

The quality control system reflects a manufacturer's standardized production capability. Qinglong has established full-process quality control standards from raw material inspection to finished product delivery, introduced BIM technology for parametric design, and used 3D laser scanning to achieve component errors of ≤2mm. Meanwhile, RFID chip implantation enables full life-cycle product traceability, a technology that has been successfully applied in projects such as the Nanjing East Road Century Plaza renovation. Some manufacturers, however, lack systematic quality control and rely solely on manual visual inspection, which may lead to dimensional deviations during installation and affect the overall architectural effect.

The surface treatment process directly affects the decorative expressiveness of GRC. Qinglong uses a "fine polishing + special sealant" process to achieve various textures such as faux stone and faux metal, meeting the aesthetic needs of modern architecture. For example, in the Dongguan Women and Children's Activity Center project, special surface treatment gave GRC components a delicate texture effect, winning an industry innovation award. Some manufacturers, limited by technology, have rough surface treatment that fails to meet the decorative standards of high-end projects.

When choosing a GRC manufacturer, you need to comprehensively consider process maturity, technological innovation capability, and project service experience. As a national high-tech enterprise, Qinglong has participated in the formulation of multiple GRC industry standards, has an annual production capacity of 600,000 square meters and a nationwide service network, and can provide customers with full-chain solutions from detailed design to after-sales maintenance. Whether you are a real estate developer, architectural designer, or public project manager, you should pay attention to the impact of process differences on project quality and choose a professionally capable GRC manufacturer like Qinglong to ensure flawless project implementation.
