What Tools Are Needed for GRC Installation: Detailed List and Usage Guide

A good workman must first sharpen his tools — Professional configuration of GRC installation tools and Qinglong's 28 years of experience

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its lightweight, high-strength, and flexible-forming characteristics. As a national high-tech enterprise with 28 years of experience in GRC detailed design, manufacturing, and installation, Qinglong Group understands well the decisive role that professional tool configuration plays in engineering quality. This article systematically outlines the core tool list and usage guide for GRC installation, providing industry peers with technical references drawn from frontline practice.

I. Classification and Function Analysis of Core GRC Installation Tools

1. Measurement and Positioning Tools: The Foundation of Millimeter-Level Precision

Accurate measurement is the prerequisite for GRC installation, requiring laser line projectors, total stations, and 3D scanning equipment. In the Nanjing East Road Century Plaza renovation project, Qinglong achieved spatial coordinate errors of ≤2mm with a Leica TS60 total station, and used a Faro 3D scanner to complete pre-assembly simulation of complex curved components, ensuring "zero-error" on-site connection. For routine flat installations, a combination of a 2-meter straightedge and feeler gauges can quickly check substrate flatness, ensuring even load distribution across GRC components.

2. Cutting and Processing Tools: Professional Equipment Suited to GRC Characteristics

Fine on-site adjustments of GRC components require cutting saws with diamond blades; fine-tooth blades with 120 teeth or more are recommended to reduce glass fiber scatter. Electric angle grinders fitted with resin grinding wheels are used for edge grinding, while water-drill hole-making techniques should be adopted for openings in special-shaped components, avoiding the material cracking caused by traditional impact drills. The CNC cutting equipment at Qinglong's production base can complete 90% of component processing in advance, greatly reducing on-site workload.

3. Anchoring and Installation Tools: Key Assurance of Structural Safety

Mechanical anchor installation requires dedicated torque wrenches. Qinglong recommends adjustable torque wrenches (range 20-200N·m) to ensure anchor pretension meets the requirements of the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018). For large GRC cladding panels, pneumatic rebar planting guns and epoxy anchoring adhesives should be equipped, with pull-out force reaching at least 15kN. The undercut anchor connection system innovatively adopted by Qinglong in the Dongguan Women and Children's Activity Center project achieves 3D adjustment of components through dedicated installation sleeves, significantly improving construction efficiency.

4. Auxiliary Tools: Detail Configurations for Improved Efficiency

Suction cup lifting equipment (load capacity ≥500kg) is suitable for moving large GRC components, and enables fine positioning when used with manual chain hoists. Joint treatment requires airless sprayers and special repair mortar; Qinglong's self-developed GRC repair material has over 90% compatibility with the substrate, effectively preventing later cracking. In addition, protective equipment such as dust masks and safety goggles is essential for ensuring construction safety.

II. Tool Management System in Qinglong's Full-Chain Services

As a GRC manufacturer integrating detailed design, manufacturing, and installation, Qinglong has established a standardized tool management process: all construction tools are regularly calibrated by third-party metrology institutions, and key equipment such as total stations undergo annual accuracy checks. In its overseas project in Malaysia, efficient cross-border construction scheduling was achieved through modular tool packing and an electronic ledger system. This standardized management model enables Qinglong to maintain a first-pass installation success rate of over 98% at an annual production capacity of 600,000 square meters.

III. Three Core Principles for Tool Selection

1. Matching principle: select tools according to GRC component thickness (usually 8-20mm) and installation height; high-rise curtain wall installation requires electric suspended platforms with anti-fall functions. 2. Safety principle: give priority to CE-certified tools, such as the German Hilti series of anchoring tools. 3. Efficiency principle: use lithium brushless tools to reduce cable constraints; the Milwaukee cordless tool sets equipped by Qinglong's construction teams can support 8 hours of continuous operation on a single charge.

Professional tool configuration is the foundation of GRC installation quality, and 28 years of industry experience have given Qinglong a deep understanding: the value of tools lies not only in precision and efficiency, but also in achieving the perfect presentation of material characteristics through scientific configuration. From the double-curved GRC curtain wall of a commercial complex in Guangzhou to the oversized special-shaped components of an airport in Saudi Arabia, Qinglong has always worked with meticulousness and the constant pursuit of excellence, integrating tool management into its full-chain service system to provide customers with expert-level solutions from design to maintenance. Choosing a professional GRC manufacturer means not only choosing quality materials, but also choosing a mature technical system validated across a thousand projects.
