Do GRC Manufacturer Products Crack Easily?

In the field of architectural decoration materials, GRC (Glass Fiber Reinforced Concrete) is widely used in all kinds of construction projects thanks to its advantages such as light weight, high strength, and flexible shaping. However, the question “Do GRC manufacturers’ products crack easily?” has always been a core concern for many potential customers when choosing GRC materials. As a GRC manufacturer with 28 years of industry experience, Qinglong will give you an in-depth analysis of the truth about GRC product cracking from multiple dimensions, including material properties, production processes, and quality control.

To judge whether GRC products are prone to cracking, you first need to understand the nature of the material. GRC is a composite of raw materials such as glass fiber, cement, and sand. The addition of glass fiber greatly improves the material’s flexural strength and toughness, fundamentally overcoming the crack-prone weakness of ordinary cement products. High-quality GRC products can reach a bending strength of over 20MPa, a performance indicator far higher than that of traditional cement components. So why are there still cases of GRC cracking on the market? The key lies in the differences in production technology and quality control standards among different GRC manufacturers. To cut costs, some small factories may reduce the glass fiber content or use inferior raw materials, resulting in insufficient structural stability, and such products are prone to cracking under the influence of environmental factors such as temperature changes and wet-dry cycles.

Qinglong GRC manufacturer eliminates cracking risks at the source by establishing a full-process quality control system. In the raw material screening stage, we strictly select highly alkali-resistant glass fiber and premium cement to ensure that every batch of materials meets the requirements of the Technical Standard for the Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018). During production, automated mixing and precise material distribution processes are adopted to ensure that the glass fiber is evenly distributed in the matrix, preventing localized strength weakness caused by fiber agglomeration or insufficient fiber content. In addition, Qinglong has also introduced steam curing technology. Through scientific control of temperature and humidity, it promotes full cement hydration, reduces internal stress, and lowers the risk of cracking at the process level.

Beyond materials and processes, the cracking of GRC products is also closely related to detailed design and construction installation. As a GRC manufacturer that integrates detailed design, production, and construction installation, Qinglong fully understands the principle that “installation counts for more than the product itself.” In the early stage of a project, the professional design team conducts structural analysis and joint optimization of GRC components based on the building’s structural characteristics and environmental conditions—for example, setting reinforcement ribs in large-span components and reserving expansion joints in areas susceptible to thermal deformation. During the construction phase, 3D laser scanning positioning and modular installation technologies are used to ensure installation precision and prevent cracking caused by concentrated installation stress. The successful application of Qinglong GRC translucent concrete components in the Nanjing East Road Century Plaza renovation project is a model of coordinated design, production, and construction, and the project has not shown any cracking problems to date.

Maintenance during long-term use is also a key part of preventing GRC products from cracking. Qinglong GRC manufacturer provides customers with comprehensive after-sales maintenance services, carrying out regular project inspections and promptly addressing issues such as surface stains and hairline cracks. At the same time, we provide customers with detailed maintenance guides—for example, avoiding the use of highly corrosive cleaning agents and checking component conditions after extreme weather—to help customers extend the service life of GRC products. Over more than 20 years, over a thousand projects undertaken by Qinglong, including the Dongguan Women and Children’s Activity Center, have kept their GRC components in good condition through scientific maintenance, fully demonstrating the durability of high-quality GRC products.

In summary, whether GRC products crack easily is not determined by the material itself, but by the overall strength of the GRC manufacturer. Choosing a GRC manufacturer like Qinglong, which has 28 years of experience and focuses on technological R&D and quality control, can fundamentally reduce the risk of cracking. As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong has always maintained a meticulous and excellence-pursuing attitude, providing customers with reliable GRC solutions so that architectural beauty endures through time.
