What to Do About GRC Product Damage During Transportation? Causes, Solutions and Prevention Measures Explained

What to Do About GRC Product Damage During Transportation? A Complete Analysis of Causes, Solutions and Preventive Measures

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight high-strength properties and rich design flexibility, is widely used in key parts such as exterior wall cladding panels and decorative mouldings of high-end projects including grand theatres, commercial complexes and landmark buildings. However, damage to GRC products during transportation often becomes a pain point affecting project schedules and costs. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group, drawing on its integrated service practice from detailed design and manufacturing to after-sales maintenance, systematically analyzes the core causes of GRC transport damage and provides professional solutions and preventive strategies.

Typical Causes and Risk Points of GRC Product Transport Damage

Transport damage to GRC products is not accidental; behind it lie multiple factors including material characteristics, packaging design and transport conditions. In terms of the material itself, although GRC components possess high flexural strength (quality products can reach over 20MPa), they may still suffer edge cracking or surface damage if subjected to severe vibration or improper stacking during transport. Secondly, lapses in packaging are a major trigger: to cut costs, some companies use simple wooden frames or packaging lacking cushioning materials, causing components to collide with each other on bumpy roads. In addition, the choice of transport vehicle (e.g., not using flatbed trucks or dedicated fixing devices), complex road conditions (e.g., sudden braking, rough road sections) and extreme weather (high-temperature exposure reducing material toughness) all increase the risk of damage. In one commercial complex project, the failure to modularly secure double-curved GRC exterior wall panels during transport resulted in honeycombing on the surface of 3 components, directly affecting installation progress and aesthetic results.

Emergency Solutions and Loss Control for Transport Damage

Once GRC product transport damage occurs, an emergency response mechanism must be activated promptly to minimize losses. First, during on-site acceptance, photos should be taken immediately to preserve evidence, and the extent of damage confirmed jointly by the supplier and the buyer—for minor edge damage (area <5%), Qinglong's special repair mortar can be used for on-site repair; with its high adhesion to the GRC substrate and matching strength, component integrity can be restored. If the damage involves structural safety (e.g., through cracks), a return/exchange process must be initiated; relying on the rapid supplementary production capacity of Qinglong's nationwide production bases (e.g., the Guangxi Nanning base with an annual capacity of 600,000 square meters), resupply within 72 hours can be ensured. Notably, the repair process must strictly follow the Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018) to avoid secondary cracking caused by improper repair. Meanwhile, through Qinglong's comprehensive after-sales maintenance system, repaired components can be provided with quality tracking for up to 5 years, ensuring long-term project stability.

Full-Chain Prevention: Eliminating GRC Transport Risks at the Source

The core of preventing transport damage lies in building a full-chain control system covering "design–packaging–transport–delivery". During the detailed design stage, Qinglong's technical team modularly splits components according to their dimensions (e.g., shaped components over 3 meters) to reduce the transport weight and fragility of individual pieces. In the packaging stage, triple protection of "EPE pearl cotton + wooden frame + metal reinforcement" is applied, with additional cushioning air bags at key positions to ensure component displacement during transport is ≤2cm. For transport plans, dedicated vehicles equipped with GPS positioning and shock-absorption devices are selected, and drivers receive specialized training on GRC product transport to avoid dangerous operations such as sudden acceleration and hard braking. In addition, Qinglong's original "transport simulation testing" technology uses computer simulation of stress conditions under different road conditions to optimize fixing plans in advance—for example, in the Nanjing Road Century Plaza renovation project, light-transmitting UHPC-GRC composite panels achieved zero-damage transport through this technology. For overseas projects (e.g., Malaysia, Saudi Arabia), moisture-proof and anti-rust treatments are added based on the characteristics of the maritime shipping environment to ensure the safety of cross-border transport.

As a national high-tech enterprise and a participant in setting GRC/UHPC industry standards, Qinglong Group has always upheld the attitude of "meticulous attention to detail and constant pursuit of excellence", incorporating the transport stage into product life-cycle management. Whether it is the cost control valued by real estate developers, the product integrity emphasized by designers, or the stringent safety requirements of public projects, Qinglong can safeguard GRC products through professional technical solutions and a mature service system. Choosing Qinglong means not only choosing high-quality UHPC/GRC/GRG/GRP materials, but also choosing a worry-free full-process experience from design to delivery.
