Sealing Treatment Methods and Construction Key Points for GRC Panel-Metal Component Connections

In the field of modern architectural decoration, GRC panels are widely used in high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to their advantages of light weight, high strength, and rich styling. The connection sealing between GRC panels and metal components, a key factor affecting building safety and durability, has always been a focus of industry attention. Qinglong Group, with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, combined with its full-chain service advantages, provides you with an in-depth analysis of solutions to this technical challenge.

Core Technical Points of Connection Sealing Between GRC Panels and Metal Components

The connection sealing between GRC panels and metal components must balance structural stability with waterproofing performance. Qinglong adopts BIM technology for joint simulation at the detailed design stage, using 3D scanning and positioning to ensure precise matching between metal connectors and GRC panels. In material selection, elastic sealants and anti-corrosion metal fittings are preferred. The sealant must meet weather resistance requirements from -40°C to 80°C, while metal components undergo hot-dip galvanizing to effectively enhance corrosion resistance. Construction strictly follows the "one pad, two coats, three seals" process: elastic gaskets are placed at the base to reduce stress transfer, interface agents are applied on contact surfaces to enhance adhesion, and finally double-layer sealant filling forms a closed-loop waterproofing system.

Quality Control Standards Throughout the Construction Process

As a national-level high-tech enterprise, Qinglong has established a full-process quality control system from detailed design to after-sales maintenance. In the GRC panel production stage, automated production lines ensure panel dimensional errors are controlled within ±2mm; during transportation, custom tooling racks are used to prevent edge and corner damage; on-site installation employs 3D laser positioning technology, achieving metal connector installation accuracy at the 0.5mm level. For different climate zones, Qinglong also provides differentiated sealing solutions: additional thermal insulation sealing layers for cold northern regions, and reinforced drainage slope design for humid southern environments. This refined construction management has enabled projects undertaken by Qinglong, such as the Dongguan Women and Children's Activity Center, to maintain excellent sealing performance after years of use.

Industry Innovation and Standard Practice Cases

As a participating unit in drafting the Technical Standard for Glass Fiber Reinforced Cement (GRC) Building Applications, Qinglong deeply integrates standard practice with project innovation. In the Nanjing Road Century Plaza renovation project, its self-developed connection joint between light-transmitting GRC panels and metal frames, through special sealing treatment, achieved a perfect balance between structural safety and light transmission. The project won the Silver Award of the First UHPC Construction Engineering Innovation Award. Qinglong's technical team has also developed adjustable connectors and displacement compensation sealing systems to address common issues in GRC-to-metal connections, effectively solving the sealing failure problem caused by thermal deformation. Related technologies have obtained multiple utility model patents.

One-Stop Solutions for Professional Clients

Addressing the core needs of professional clients such as real estate developers and architectural design institutes, Qinglong provides "turnkey" services from scheme optimization to later-stage maintenance. In the early project stage, the technical team provides detailed design solutions for GRC panel and metal component connections based on factors such as architectural styling and usage environment; the production stage achieves quality traceability through RFID chips; after installation, 2 years of free maintenance and regular inspection services are provided. This full-chain service model has been highly recognized by well-known real estate groups such as Poly and China Overseas, becoming Qinglong's core competitiveness in establishing industry influence in the GRC segment.
