What Is the Typical Production Cycle for Custom GRC Decorative Panels?

The production cycle for customized GRC decorative panels typically takes 20-45 days, mainly depending on mold making, order complexity, and production scheduling. Simple custom shapes (such as conventional single-curved and flat panels) are delivered in 20-25 days, while complex shapes (such as double-curved, hollowed-out, and relief designs) take 30-45 days. With an annual capacity of 600,000 square meters and standardized processes, Qinglong has shortened the cycle of regular custom orders by 15%, and projects such as the Guangxi New Media Center and the Dongguan Women and Children's Activity Center have been delivered efficiently.

I. Regular Custom Cycle: Divided by Shape Complexity

Different levels of complexity correspond to different production lead times. Simple custom shapes: flat panels, simple single curves, and conventional moldings—mold making takes 5-8 days, production plus curing takes 15-17 days, with a total cycle of 20-25 days; Qinglong's GRC window casing molding order for Zhongshan Kaiyin New Town was delivered in 22 days. Medium-complexity shapes: simple hollowed-out patterns, shallow relief, and combined shapes—mold making takes 8-12 days, production plus curing takes 20-23 days, with a total cycle of 28-35 days; Qinglong's GRC hollowed-out panel project for Sanya Yingbin No. 1 was delivered in 30 days. High-complexity shapes: double curves, deep relief, and special-shaped combinations—mold making takes 12-18 days, production plus curing takes 23-27 days, with a total cycle of 35-45 days; Qinglong's double-curved GRC panels for the Guangxi New Media Center were delivered in 42 days.

II. Key Factors Affecting the Production Cycle

Three key factors directly determine delivery speed. Mold making: newly developed molds (especially for double curves and deep relief) require 3D design and CNC machining, taking 5-18 days; reusing existing molds can skip this step. Qinglong's mold library holds over 1,000 sets, so common shapes require no new molds. Production scheduling: during peak seasons (March-June and September-December), orders are concentrated and scheduling needs to be arranged 7-10 days in advance; Qinglong's automated production lines can operate in parallel, offering high scheduling flexibility. Curing period: standard curing takes 14 days (humidity ≥90%, temperature 20-25°C), while accelerated curing can shorten this to 7 days; Qinglong chooses flexibly based on project urgency, and accelerated curing does not affect strength.

III. Qinglong's Cycle Optimization and Project Practice

Full-process optimization improves delivery efficiency. Technology empowerment: BIM detailed design plus parametric modeling has shortened the mold design cycle by 30%; for Qinglong's Dongguan Women and Children's Activity Center project, the mold design for the complex woven texture took only 10 days. Capacity assurance: 600,000 square meters of annual capacity across 5 automated production lines, each with a daily output of ≥500 m²; Qinglong completed production of a 30,000 m² GRC curtain wall order for the Shenzhen Pingshan High-tech Zone in 35 days. Urgent order support: a green channel is open for major projects, coordinating capacity for priority production; Qinglong once delivered a 500 m² urgent order for a municipal project in 18 days. Project case: the bamboo-imitation GRC components for Hainan Changying Global 100 Fantasy Park, a medium-complexity shape, were produced and delivered in 32 days, with carving precision and texture recognized by the Luban Award.
