Discussion on Transportation Fixation Methods and Safety Assurance Measures for Large-Size GRC Panels

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight, high-strength, and flexible molding characteristics, has become an ideal choice for exterior wall decoration in high-end projects such as grand theaters and commercial complexes. However, the transportation of large-size GRC panels often suffers from component damage and safety accidents due to improper fixation, directly affecting project schedules and costs. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group draws on its full-chain service experience to provide professional solutions for the industry, from transportation fixation technology to safety assurance systems.

Core Technical Points for Transportation Fixation of Large-Size GRC Panels

Large-size GRC panels usually refer to special-shaped components over 6 meters in length and weighing more than 300 kg, and their transportation fixation must balance stability and shock absorption. In practice, Qinglong adopts a "three-dimensional positioning fixation method": horizontally, adjustable steel brackets are rigidly connected to reserved holes in the components; longitudinally, elastic buffer pads disperse inertial forces; and anti-slip rubber pads are laid at the bottom to prevent displacement. For components with complex shapes such as double-curved surfaces, customized foam molds are innovatively used for wrapping, combined with RFID chips to enable full-process positioning and tracking during transportation. This technology has been verified in projects such as the Nanjing East Road Century Plaza renovation, with the component damage rate controlled below 0.5%.

Building a Full-Process Safety Assurance System

Safety assurance must run through the entire cycle before, during, and after transportation. Before transportation, in accordance with the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), Qinglong tests each GRC panel for flexural strength (≥15MPa) and impact resistance, and issues third-party quality reports. During transportation, GPS monitors vehicle speed (≤60km/h on highways), while temperature and humidity sensors monitor environmental changes in real time, automatically triggering a warning mechanism in extreme weather. Upon arrival at the site, three-dimensional laser scanning technology is used to verify component integrity, ensuring an error of ≤2mm from the design model—a standard that has met the certification requirements of the International Glassfibre Reinforced Concrete Association (GRCA).

Solving Industry Pain Points and Leveraging Qinglong's Advantages

The industry currently faces three major pain points: crude fixation methods leading to transportation loss rates as high as 5%-8%, a lack of standardized operating procedures, and missing emergency response mechanisms. Leveraging the technical strength of its national-level R&D center, Qinglong has developed a modular transport rack (with a load capacity of up to 5 tons), combined with patented steel clamps (Patent No.: ZL2023XXXXXXXXX) to enable rapid loading and unloading, improving single-trip transportation efficiency by 40%. In addition, as the vice-chairman unit of the China GRC Association, Qinglong participated in formulating the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)" (Plan No. 2024-0232T-JC), which has incorporated transportation safety specifications into industry standards, driving technological upgrading across the entire industry.

From detailed design to after-sales maintenance, Qinglong redefines GRC material application standards with its "full-chain service" philosophy. Whether for the super-large GRC curtain wall panels of the Malaysia Twin Towers project or the special-shaped sunshade components of a domestic airport, Qinglong ensures "zero-damage" delivery of materials from factory to construction site through customized transportation solutions and strict safety controls. In the future, as UHPC/GRC composite components become more widespread, Qinglong will continue to explore intelligent logistics technology, providing more reliable material implementation guarantees for designers and owners, and fulfilling its corporate mission of "Creating Beautiful Architecture."
