What Is the Production Process of GRC?

The GRC production process is complex, which affects product quality. Drawing on 28 years of experience, Qinglong Group has developed a four-step method—batching, forming, curing, and finishing—to ensure high-quality products. Automated production lines with precise control deliver excellent product consistency.

Batching is the first step. Raw materials are precisely weighed with an error of ≤0.5%. The water-binder ratio is controlled at 0.30–0.35 for excellent workability. Qinglong Group uses an automatic batching system for high efficiency and stable quality. Fibers are added evenly to prevent clumping and ensure reinforcement performance.

Forming is critical. Spraying or casting achieves dense formation. Robotic operation ensures high uniformity. In the Wuhan Hanxiu Theater project, Qinglong Group perfectly realized complex shapes. Vibration removes entrapped air to avoid defects. Fine craftsmanship yields superior products.

Curing promotes strength development. Temperature and humidity are controlled with sufficient curing time. Qinglong Group's intelligent curing ensures stable performance. Finishing and trimming meet all requirements. Quality craftsmanship creates excellent products.
