What Are the Steps of GRC Installation? Standardized Process and Customized Execution Explained

GRC installation is a systematic project that must follow the standardized process of "preparation - precise construction - acceptance and maintenance", while making customized adjustments based on component type and project scenario. Scientific installation steps not only ensure construction quality and safety, but also improve efficiency and reduce later maintenance costs. As a full-chain service provider with 28 years of experience, Qinglong has broken the installation process down into six core steps, whose feasibility and reliability have been verified across thousands of projects.

Preliminary Preparation: Laying the Foundation for Installation. Three major tasks must be completed before installation: technical disclosure, component acceptance, and site preparation. During the technical disclosure stage, Qinglong's design and construction teams brief site personnel on the installation plan, technical requirements, and safety regulations, and provide detailed installation node drawings, especially for complex-shaped components; during component acceptance, GRC components must be checked for dimensional accuracy, surface quality, and reserved hole positions to ensure compliance with design requirements. Components produced by Qinglong undergo strict inspection before leaving the factory, so on-site acceptance only requires verifying numbers and appearance; site preparation includes cleaning the substrate and erecting scaffolding or working platforms to ensure a safe and orderly installation environment. For example, in the Hainan Changying Universal 100 Fantasy Park project, Qinglong completed the scaffolding and substrate treatment around the theme buildings in advance, paving the way for subsequent installation.

Substrate Treatment and Layout Positioning: Precisely Controlling Installation Benchmarks. Substrate treatment requires ensuring the substrate is flat, firm, and clean; for uneven substrates, cement mortar leveling or welded brackets are used for adjustment. Layout positioning is the key to installation accuracy: Qinglong uses professional tools such as laser rangefinders and theodolites, combined with BIM technology, to precisely project design coordinates onto the substrate, defining the installation position, elevation, and spacing of components. In the Guangxi New Media Center project, since the building features a twisted irregular shape, Qinglong used three-dimensional layout technology to define precise installation positions for each unique GRC hyperbolic panel, ensuring the coordination of the overall form.

Component Installation and Temporary Fixing: Advancing the Core Process in an Orderly Manner. The appropriate installation method is chosen according to component type: standardized components can be installed sequentially by number, while complex components require step-by-step hoisting. During installation, the GRC component is first aligned with the positioning lines, its position, elevation, and flatness are adjusted, and then it is temporarily fixed to prevent displacement. In the Wuhan Han Show Theatre project, when installing 15mm-thick GRC carved panels, Qinglong used suction-cup lifting devices to place them gently, together with temporary supports, ensuring that the thin-walled components were neither damaged nor deformed during installation; for large GRC components, segmented hoisting and point-by-point fixing were adopted to guarantee installation safety and precision.

Permanent Fixing and Sealing: Ensuring Long-Term Stability. Once the temporary fixing is confirmed to be correct, permanent fixing is carried out: dry-hung components are connected to the substrate through hangers and bolts, while bonded components are reinforced with special adhesives. All fixing materials selected by Qinglong have passed corrosion-resistance and aging-resistance tests to ensure long-term safety of use. Sealing is key to waterproofing and moisture resistance: high-performance sealant is filled into the joints between components. Qinglong's construction team uses professional caulking guns to apply the sealant evenly, ensuring tight sealing without air bubbles, while cleaning off excess sealant to keep the appearance neat. For example, in the Hainan International Convention and Exhibition Center project, Qinglong's thorough sealing effectively withstood erosion from the rainy climate.

Acceptance and Later Maintenance: Closing the Loop on Installation Results. After installation is completed, acceptance is carried out according to industry standards, checking indicators such as component installation accuracy, fixing strength, and sealing effectiveness. Qinglong's acceptance team issues a detailed acceptance report to ensure the project meets standards. In the later maintenance stage, regular inspections and maintenance guidance are provided, such as reminding customers to regularly clean stains from component surfaces, check the aging of sealant, and carry out timely repairs. This installation process, combining standardization with customization, keeps Qinglong's GRC installation projects consistently high-quality, making them an industry benchmark.
