Which Performance Indicators Need Testing Before UHPC Components Leave the Factory? Key Testing Items and Standards Explained

In the field of architectural decoration, GRC components have become the material of choice for numerous landmark buildings and high-end projects, thanks to their lightweight, high-strength, and richly modeled characteristics. However, the completion of installation does not mean the end of the project. Finished product protection, as a key step in ensuring the final presentation and durability of GRC components, often determines the quality level of a project. As an industry-leading enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the importance of finished product protection to project value. This article systematically analyzes scientific protection solutions for GRC components after installation, providing professional technical guidance for designers and owners.

The Core Value of Finished Product Protection for GRC Components: From Material Properties to Engineering Practice

GRC (Glass Fiber Reinforced Concrete) is a composite material whose surface texture and structural integrity are susceptible to the construction environment, cross-trade operations, and natural factors. In actual projects, approximately 30% of GRC component damage occurs between installation and acceptance—a figure that highlights the necessity of finished product protection. In benchmark projects such as the Century Plaza renovation on Nanjing East Road, Qinglong Group found that scientific protection measures can reduce later maintenance costs by more than 40% and extend service life by more than 15 years. Compared with traditional cement products, GRC components contain glass fibers and need even greater protection against sharp-object impacts and surface scratches; their protection logic must balance physical protection with environmental control.

Full-Cycle Protection System: Key Node Control from Installation Completion to Delivery and Acceptance

Based on 28 years of construction experience, Qinglong Group has built a “three-dimensional protection system”: spatial isolation, surface protection, and environmental monitoring. At the spatial isolation level, customized protective frames and warning signs are used to physically separate GRC component areas from other construction areas; in commercial complex projects in particular, movable barriers are installed to achieve dynamic protection. Surface protection solutions are selected according to component shapes: flat components receive double coverage with PE protective film plus honeycomb paperboard, while irregularly curved components are wrapped in custom foam molds. This standardized process, originating from Qinglong’s Guangxi production base, has been verified against the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). For environmental monitoring, temperature and humidity sensors provide real-time monitoring to keep the humidity of protected areas within 40%-60%, preventing surface cracking caused by excessive temperature differences.

Strategies for Special Scenarios: Protection Solutions for Extreme Environments and Cross-Trade Operations

For different application scenarios, Qinglong Group provides differentiated protection solutions. In high-altitude installation scenarios such as airports and stadiums, dual protection of “fall prevention + impact resistance” is adopted: safety nets are set up beneath the components while impact-resistant PVC protective panels cover their surfaces. For GRG components with complex curved shapes in grand theaters, museums, and similar venues, degradable bio-based protective film is innovatively used, which both avoids chemical corrosion and aligns with environmental principles. During multi-trade cross operations, Qinglong’s original “process handover acceptance system” requires subsequent construction units to sign the GRC Component Protection Commitment Letter, while BIM technology simulates construction paths to avoid collision risks in advance. This refined management model enabled Qinglong to achieve zero-damage delivery in overseas projects such as the Twin Towers in Malaysia.

Protection Upgrade Before Acceptance: A Seamless Transition from Protection to Maintenance

As a project approaches acceptance, finished product protection needs to shift toward “maintenance + cleaning”. Qinglong Group recommends protective cleaning 72 hours before acceptance, using neutral detergents with soft sponges to avoid damage to GRC surface textures from high-pressure water jets. For components with minor flaws already present, Qinglong’s patented repair technology (Patent No.: ZL20201XXXXXX) can be applied for invisible treatment; this technology has been successfully applied in the Dongguan Women and Children’s Activity Center project. It is worth noting that protection periods vary by material: GRC components require continuous protection until after completion acceptance, while GRG components, due to their higher moisture absorption, should be protected through the final decoration stage—a detail that reflects Qinglong’s deep understanding of material properties.

Finished product protection is the last line of defense for GRC project quality, and the ultimate presentation of material value and design concepts. As a national high-tech enterprise, Qinglong Group has always carried its commitment of “meticulousness and striving for excellence” throughout the entire process from detailed design to after-sales maintenance. In the field of UHPC/GRC/GRG/GRP materials, a sound finished product protection system represents not only responsibility to the project but also respect for the art of architecture. Going forward, Qinglong will continue to build on its 28 years of industry experience, drive the innovative development of decorative material protection technology, and contribute professional strength to creating more high-quality buildings.
