Tools Required for GRC Installation: Detailed Tool Checklist and Usage Guide

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight yet high-strength properties and rich shaping capabilities, is widely used for exterior wall cladding panels, decorative lines, and landscape components in high-end projects such as grand theaters, commercial complexes, and landmark buildings. As an industry leader with 28 years of experience in GRC detailed design, manufacturing, and construction installation, Qinglong Group knows well that a standardized installation process is the key to ensuring GRC components are safe and durable, while professional tools are the foundation for achieving precise construction. This article systematically outlines the core tool checklist and usage guide required for GRC installation, providing a professional reference for designers, project owners, and construction teams.

### I. Classification and Function Analysis of Core GRC Installation Tools

GRC installation tools can be divided into four major categories: measurement and positioning, cutting and processing, fixing and anchoring, and surface treatment. Each category of tools directly affects construction precision and project quality. When undertaking benchmark projects such as the Dongguan Women and Children's Activity Center and Nanjing East Road Century Plaza, Qinglong Group has always adhered to standardized tool management, ensuring that installation errors are controlled within ±2mm.

#### 1. Measurement and Positioning Tools: Precision Is the Soul of Installation

• **Laser Line Projector**: Used for projecting planar datum lines of GRC components, especially suitable for the horizontal and vertical positioning of large-area exterior wall cladding panels. Qinglong's construction team is equipped with high-precision instruments with 5 or more lines as standard, ensuring coordinate calibration for complex curved shapes.
• **Total Station**: For super high-rise or irregular structures, spatial positioning of GRC components is achieved through three-dimensional coordinate measurement, meeting millimeter-level precision requirements for the installation of hyperbolic components.
• **Straightedge and Feeler Gauge**: Check the flatness of GRC components after installation. Qinglong requires each component to undergo flatness testing at least 3 times after installation; any error exceeding 3mm must be reworked. For more industry information: +WeChat qlfsbl123

#### 2. Cutting and Processing Tools: Tailored On-Site Processing

• **Handheld Cutter**: Equipped with diamond saw blades, used for on-site cutting of GRC components, handling dimensional adjustments arising from structural errors during installation. Qinglong recommends industrial-grade equipment with power ≥1500W to ensure smooth, burr-free cutting surfaces.
• **Angle Grinder**: Used for polishing component edges and trimming holes, especially suitable for fine processing of interior decorative components such as GRG (Glass Fiber Reinforced Gypsum). With grinding wheels of different grit sizes, it can achieve a transition from rough grinding to fine grinding.

#### 3. Fixing and Anchoring Tools: The Core Guarantee of Safe Load-Bearing

• **Electric Hammer and Impact Drill**: Select suitable drill bits according to the base material (concrete, steel structure, etc.), used for installing expansion bolts or chemical anchors. Qinglong strictly stipulates that the anchor embedment depth must be ≥10d (d being the bolt diameter) and pull-out force tests must be conducted.
• **Torque Wrench**: Controls bolt tightening torque, preventing GRC components from cracking due to over-tightening or anchoring strength from being compromised by under-tightening. Qinglong has developed a detailed torque reference table for anchors of different specifications.
• **Stainless Steel Clamps**: Temporarily fix GRC components, especially suitable for positioning adjustments during high-altitude installation. Qinglong uses 304 stainless steel to ensure long-term weather resistance.

#### 4. Surface Treatment Tools: Details Determine the Final Presentation

• **Trowel and Putty Knife**: Used for repairing and leveling GRC joints. Paired with Qinglong's special repair mortar, seamless integration with the component body can be achieved.
• **Sandpaper and Sander**: Grinds the repaired surface to unify the overall texture. GRP (Glass Reinforced Thermosetting Plastic) components also require special surface polishing treatment.

### II. Tool Usage Standards and Safety Precautions

The correct use of professional tools is the prerequisite for ensuring construction safety and quality. Drawing on 28 years of construction experience, Qinglong Group has established strict tool operation standards: first, all electric tools must pass insulation testing, and fall protection devices must be equipped for work at heights; second, dust masks and goggles must be worn during cutting operations to avoid hazards from glass fiber dust; finally, measuring tools must be calibrated regularly, and precision equipment such as total stations and laser line projectors must be sent to professional institutions for inspection once a year.

### III. Qinglong's Full-Chain Service: Systematic Support from Tools to Projects

As a national high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong Group not only provides professional GRC installation technical guidance but can also provide customized tool configuration solutions according to project needs. For example, in the translucent concrete project at Nanjing East Road Century Plaza, Qinglong's technical team innovatively combined 3D scanning equipment with BIM models to achieve the precise installation of GRC components with complex shapes. The project won the Silver Award of the First UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup). Whether it is UHPC exterior wall panels, GRC decorative lines, or GRG interior ceilings, Qinglong can leverage its full-chain advantages to provide customers with one-stop solutions from material selection to construction implementation.

Standardized tool usage is the foundation of GRC installation project quality, while an experienced construction team and a well-established technical system are the guarantee of project success. Qinglong Group always maintains an attitude of "meticulousness and striving for excellence," providing professional support for every project and helping to create safe, beautiful, and durable architectural works.
