How to Communicate and Collaborate Effectively with UHPC Manufacturers?

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) is widely used for exterior wall cladding panels, decorative moldings, and landscape components in high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its lightweight yet high-strength properties and rich design versatility. However, the fixing quality after GRC installation directly affects building safety and service life. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will explain in detail, from a professional perspective, the core methods and key precautions for GRC installation and fixing, providing an authoritative technical reference for designers, owners, and contractors.

GRC installation and fixing must balance structural safety with decorative effect. Common fixing methods fall mainly into two categories: mechanical anchoring and chemical anchoring. Mechanical anchoring connects GRC components directly to the main structure through metal connectors (such as angle steel and embedded parts), and is suitable for scenarios with heavier loads or higher substrate strength. Its advantages lie in clear force transmission and convenient installation; Qinglong's standardized connector production line at its Nanning production base ensures accessory precision of ±0.5mm. Chemical anchoring uses high-strength rebar planting adhesive to embed bolts or steel bars into the substrate structure, and is suitable for complex shapes or cases where the substrate is concrete or steel structure. Qinglong's independently developed rebar planting adhesive has been third-party tested to achieve a pull-out force of over 20MPa, meeting the stringent requirements of the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018).

GRC fixing techniques vary significantly across different application scenarios. Exterior wall cladding panels require a composite fixing system of "flexible connection + rigid restriction," using spring washers to absorb thermal deformation stress and prevent cracking or falling off caused by thermal expansion and contraction. Decorative moldings (such as Roman columns and cornices) require special attention to node concealment; Qinglong's BIM pre-assembly technology can simulate the installation process in advance, ensuring perfect integration of connectors with the molding shapes. For landscape components (benches, flower beds), ground settlement must be considered during fixing; adjustable bases are recommended, combined with Qinglong's patented anti-loosening nuts (Patent No. ZL2023XXXXXXXXX) to achieve long-term stability.

Precautions for GRC fixing construction span the entire installation process. In the preliminary preparation stage, the substrate must undergo strength testing (concrete substrate strength no lower than C25), and surface dust and oil stains must be cleaned. During installation, a 3D laser projector should be used for positioning to ensure component verticality deviation ≤3mm/m. Post-installed embedded parts require pull-out testing, with each connector's pull-out force ≥5kN. As a national high-tech enterprise, Qinglong strictly implements the "three-inspection system" during construction and achieves quality traceability through RFID chips. In the Nanjing East Road Century Plaza renovation project it undertook, the fixing precision of GRC translucent concrete components was controlled within ±1mm, winning the Silver Award of the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

Maintenance and inspection during long-term use are equally critical. It is recommended to conduct a comprehensive inspection of the GRC fixing system annually, focusing on connector corrosion, bolt tightness, and sealant aging. Qinglong's after-sales maintenance services include on-site evaluation by a professional inspection team; for coastal high-humidity environments or severely cold regions, customized anti-corrosion and anti-rust solutions are available. The GRC fixing system of its overseas project (a commercial complex in Malaysia) remains intact after 10 years of use. As a vice-chairman unit of the China GRC Association, Qinglong always adheres to the principle of "meticulousness and excellence," delivering safe and reliable GRC decorative projects for clients through full-chain services covering in-depth design, manufacturing, construction and installation, and after-sales maintenance.
