What Are the Steps for GRC Installation? 2024 Standardized Installation Process and Quality Control

The key to successful GRC installation lies in standardized procedures and refined control. From preliminary preparation to final acceptance, every step must strictly follow specifications. Drawing on 28 years of hands-on experience, Qinglong GRC manufacturer has summarized standardized installation procedures for the entire process, ensuring that projects meet both quality and efficiency targets.

Preliminary Preparation: Laying the Foundation for Installation

Preliminary preparation is the prerequisite for successful installation, covering technical disclosure, site survey, and component inspection. During the technical disclosure stage, Qinglong's technical team coordinates with the construction party on design drawings and detailed installation node drawings to clarify installation requirements and quality standards. The site survey requires verifying the strength of the base structure and the positions of embedded parts, and clearing obstacles in the installation area to ensure construction conditions meet standards. Component inspection requires checking the dimensions, strength, and appearance of GRC components and removing damaged or deformed products. For example, in the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, Qinglong inspected 30,000 square meters of GRC curtain wall panels piece by piece in advance to ensure an error-free installation foundation.

Positioning and Layout: Precise Position Control

Positioning and layout directly affect installation accuracy and require professional measuring tools for precise positioning. The Qinglong team uses total stations, laser levels, and other equipment to snap reference lines, elevation lines, and position lines for component installation according to the design drawings, and to mark the positions of embedded parts or fixing points. For components with complex shapes, such as the hyperbolic GRC panels of the Guangxi New Media Center, BIM technology is also applied for 3D simulated positioning to avoid installation collision risks in advance. After positioning is completed, a review must be carried out to ensure that reference line deviation is ≤2mm and fixing point position error is ≤3mm, providing a precise basis for subsequent installation.

Lifting and Fixing: Safe and Efficient Installation

Lifting and fixing must balance safety and precision, proceeding step by step in an orderly manner. First, select appropriate lifting equipment based on the weight and dimensions of the components, and use special lifting tools for smooth hoisting to avoid collision damage to components. Second, place the components precisely at the positioned locations, temporarily fix them, and then adjust the levelness, verticality, and joint width—Qinglong requires level and verticality deviation to be ≤3mm, with uniform and consistent joint widths. Finally, perform permanent fixing using the preset fixing method (dry hanging, welding, bonding, etc.). For example, the GRC hyperbolic panels of Poly Peninsula No. 1 in Hainan use a dry-hanging system with installation precision controlled within ±2mm, ensuring firmness and reliability.

Sealing and Finishing: Perfecting Detail Quality

Sealing and finishing is the final step in safeguarding installation quality, including joint treatment and acceptance cleaning. Qinglong uses special silicone sealant to fill component joints, combined with foam strips and backing rods to ensure tight sealing and prevent rainwater penetration. Anti-corrosion treatment is applied to welded and bolted connections to extend service life. After completion, a comprehensive acceptance check is conducted to inspect installation accuracy, fixing firmness, sealing effectiveness, and other indicators. Once acceptance is passed, the construction site and component surfaces are cleaned to ensure a neat appearance. For example, in the GRC panel installation of the Wuhan Han Show Theatre, after sealing, a 24-hour waterproof test showed no water leakage whatsoever, ensuring long-term use quality.

The standardized procedures of GRC installation are the guarantee of quality and efficiency. Through refined control of the entire process, Qinglong GRC manufacturer ensures that every installation step follows established rules. Whether for large public construction projects or small decorative works, following standardized procedures combined with professional technical support achieves precise, safe, and efficient GRC installation, adding quality decorative effects to buildings.
