Wushan Outdoor Landscape GRC Panels, Anti-Weathering Treatment Process for Scenic-Area Irregular GRC Components

As the core carrier of special-shaped components in scenic areas, the long-term service stability of Wushan outdoor landscape GRC panels directly determines the lifecycle and operation/maintenance costs of the scenic area landscape. Many scenic area projects, at the early material selection stage, often encounter problems such as surface powdering, uneven color variation, and localized cracking within 1-2 years of component delivery due to insufficient understanding of GRC weathering resistance processes, which not only undermines the overall aesthetic effect of the landscape but also adds extra maintenance pressure on the scenic area later on. As a manufacturer with nearly 30 years of full-chain GRC service experience, the Qinglong GRC team has participated in dozens of landscape component customization projects for well-known domestic 5A-level scenic areas. For the weathering resistance treatment of GRC components in extreme outdoor environments, it has developed a complete process system covering everything from raw material ratios to later-stage protection, effectively ensuring that special-shaped GRC components in mountainous scenic areas like Wushan serve stably in outdoor environments for more than 15 years.

I. Analysis of the Core Causes of Outdoor Weathering of Special-shaped GRC Components in Scenic Areas Unlike GRC cladding panels on ordinary building exterior walls, the mountainous scenic area environment where Wushan outdoor landscape GRC panels are located faces the combined impact of multiple weathering factors: on one hand, scenic areas see large day-night temperature differences, year-round rainwater scouring and direct ultraviolet exposure, along with freeze-thaw cycle erosion in winter, so the surface mortar layer of ordinary GRC components easily develops powdering caused by pore expansion; on the other hand, the curved corners and joint gaps of special-shaped components are stress concentration points that, under conventional treatment processes, easily become breakthrough points for weathering erosion, ultimately leading to safety hazards such as component deformation and local detachment. Many project owners easily fall into the early-stage misconception that "standard GRC raw materials alone ensure weathering resistance," ignoring process optimization specific to special-shaped components, which is also the core reason why many landscape projects suffer appearance deterioration shortly after delivery.

II. Qinglong's Core Weathering Resistance Treatment Processes for Wushan Outdoor Landscape GRC Panels To meet the special requirements of special-shaped GRC components in scenic areas, the Qinglong GRC team's weathering resistance treatment process is implemented mainly from three dimensions: first, dedicated ratio optimization on the raw material side—adjusting the proportion of mineral admixtures in the basic GRC (glass fiber reinforced concrete) formula to raise the density of the component matrix by more than 30%, fundamentally reducing penetration channels for water and corrosive media, while keeping the flexural strength of special-shaped components stable above 22MPa to meet the wind load requirements of mountainous environments; second, dedicated protective layer treatment for special-shaped components—for edge and corner positions of complex shapes such as double curved surfaces and openwork designs, a process of two roller-coating passes plus partial brush coating is adopted to ensure dead-angle-free coverage of the protective layer, avoiding the uneven coating thickness at corners that occurs with conventional spray coating processes; third, special sealing treatment for joint nodes—node adaptation for pre-assembly is completed before components leave the factory, and joint gaps are pre-treated with weather-resistant sealing materials to prevent water ingress into gaps after on-site installation.

III. The Core Value of Full-Process Assurance for Scenic Area GRC Components For scenic area project owners, choosing a mature GRC manufacturer to provide full-chain services ensures long-term performance far better than simply purchasing components. As an industry organization that participated in drafting the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)," Qinglong has an annual GRC production capacity of 600,000 square meters. For scenic area projects like Wushan, it gets involved from the early detailed design stage, anticipating in advance the stress concentration points and weathering-vulnerable positions of special-shaped components, while matching subsequent installation guidance and regular maintenance services, keeping project owners from falling into the predicament of repeated later repairs. To date, multiple similar mountainous scenic area projects in China delivered with this process system have recorded appearance deterioration rates over 5 consecutive years that are 15% lower than the industry average, fully verifying the stability of the process.
