How to Evaluate Surface Treatment Processes of GRC Manufacturers: Key Indicators, Procedures, and Optimization Strategies Explained

In the field of architectural decoration materials, surface treatment processes are the core factor determining the quality and value of GRC products. As a Qinglong GRC manufacturer with 28 years of industry experience, we deeply understand the critical role a scientific process evaluation system plays in project success. This article analyzes the evaluation methodology for GRC surface treatment processes from three dimensions—key indicators, whole-process control, and optimization strategies—to provide the industry with practical quality improvement solutions.

Core Indicator System for GRC Surface Treatment Process Evaluation

The evaluation of GRC surface treatment processes must be built on both quantitative data and visual standards. In terms of physical performance indicators, Qinglong GRC manufacturer focuses on surface flatness (error controlled within ±2mm/m²), coating adhesion (Grade 0 standard in cross-cut testing), and weather resistance (no cracking or discoloration after 1,000 hours of UV aging tests). Take the Nanjing East Road Century Plaza renovation project as an example: its translucent concrete surface treatment, achieved through precision grinding and nano-coating technology, delivered a light transmittance of ≥85% with uniform surface gloss, thanks to strict control of surface porosity (kept below 3%) and color difference (ΔE≤1.5).

Standardized Practice of Whole-Process Control

Qinglong GRC manufacturer integrates surface treatment process evaluation into the entire production cycle: in the detailed design phase, BIM technology simulates surface texture flow to ensure the machinability of complexly shaped components; in production, a "three-inspection system" is implemented, with the first article requiring joint confirmation of surface standards by the technical, production, and quality inspection departments; during installation, 3D laser scanning positioning ensures surface flatness at on-site joints. In the Dongguan Women and Children's Activity Center project, this process control kept the overall error of the GRC curtain wall surface within 5mm, far surpassing the industry average standard of 8mm. This full-chain control capability is precisely the core competitive strength of Qinglong as a national-level high-tech enterprise.

Technical Pathways and Innovation Directions for Process Optimization

In response to high-end projects' pursuit of perfection in surface effects, Qinglong GRC manufacturer has established a three-tier optimization mechanism: at the basic level, adjusting fiber ratios and vibration parameters to reduce surface bubble formation; at the process level, introducing robotic automated grinding systems to boost processing efficiency by 30%; at the innovation level, developing a library of 8 types of surface effect processes, including stone-look and metal-look finishes, to meet diverse design needs. Notably, the "dual-coating protection system" we innovatively applied in a landmark project in Malaysia raised the GRC surface's salt spray resistance to over 5,000 hours in tropical marine climates—a technology that has been granted a national invention patent.

The evaluation of surface treatment processes is not only a quality control measure but also a key path to enhancing product value. Through 28 years of technical accumulation, Qinglong GRC manufacturer has built a complete system spanning indicator definition, process control, and technological innovation—this is the professional confidence we hold as a contributing unit to the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)". In the future, as UHPC/GRC/GRG/GRP materials see widespread application in architectural decoration, refined surface treatment processes will become a key manifestation of manufacturers' core competitiveness, while a scientific evaluation system will remain the cornerstone of quality assurance.
