What Tools Are Needed for GRC Installation? Tool List and Qinglong Group's Standardized Operation System

The tools required for GRC installation vary according to installation stage and component type. A complete tool system should cover five key stages: surveying and layout, component handling, positioning and adjustment, fixing and connection, and sealing. Based on 28 years of construction experience across more than a thousand projects, Qinglong Group divides GRC installation tools into two categories: basic general-purpose tools and specialized professional tools. Basic tools include laser levels, impact drills, torque wrenches, screwdrivers, lifting slings, etc.; specialized tools include 3D laser scanners, vacuum suction cup lifters, and dedicated adjustable anchors. In the Nanning Wuxiang China Resources MixC One project, we equipped the installation team with vacuum suction cups fitted with pressure sensors to ensure absolute safety when hoisting large GRC panels. A scientific and rational tool configuration is the material foundation for ensuring GRC installation quality, efficiency, and safety.

Surveying and Layout Tools Are the Starting Point of Precision

Accurate surveying is the first step toward a perfect installation. Basic projects need to be equipped with high-precision laser levels, theodolites, steel tape measures, chalk lines, etc. For projects with complex shapes or extremely high installation precision requirements, such as the double-curved panels of the Wuhan Han Show Theatre, the Qinglong team introduced 3D laser scanners and total stations to scan and verify the main structure, generating digital point cloud models that provide accurate benchmarks for subsequent installation, avoiding installation difficulties caused by structural deviations at the source.

Handling and Hoisting Tools Ensure Safety and Efficiency

GRC components are fragile, so handling and hoisting require special care. For small components, manual suction cups or simple lifting slings are sufficient. For large panels (e.g., over 2 square meters), mechanical assistance such as small winches, gantry frames, or tower cranes must be used. Qinglong Group widely uses vacuum suction cup lifters on large projects; their multiple suction cups distribute the suction force evenly for smooth hoisting, and they are equipped with anti-fall safety devices, greatly improving safety and efficiency.

Adjustment and Fixing Tools Achieve Precise Positioning

After components are initially positioned, fine-tuning tools are needed to bring them to their design positions. Common tools include crowbars, jacks, rubber mallets, etc. The core lies in the connectors themselves: the '3D adjustable metal anchors' developed by Qinglong Group are themselves precision adjustment tools. By tightening or loosening the bolts, fine adjustments can be made in three dimensions—up and down, left and right, front and back—and finally tightened with a torque wrench to the design values, ensuring reliable connections.

Sealing and Finishing Tools Complete the Final Process

Treating panel joints after installation is crucial. Caulking guns, masking tape, scrapers, etc. are needed. Choosing special nozzles with good compatibility with both GRC and the sealant produces uniform and full sealant joints. In the roofing works of the Hainan International Convention and Exhibition Center, we set strict requirements on the sealant application environment as well as joint width and thickness, and used dedicated edge-pressing tools to ensure the sealant joints are aesthetically pleasing and durable.

Qinglong Group prepares a detailed 'Installation Work Instruction' for each project, including a tool list and usage specifications. Through standardized tool management and operating procedures, it provides a solid guarantee for GRC installation quality.
