Can You Produce GRC Yourself? DIY Feasibility Analysis vs. Professional Production Value

Individuals or small teams producing GRC on their own face extremely high technical barriers and equipment requirements, making actual feasibility very low. GRC production requires professional raw material mix design, specialized production equipment, a strict quality control system, and extensive process experience—conditions that ordinary DIY efforts can hardly meet. Qinglong Group's 28 years of industrialization experience shows that producing high-quality GRC is technology-intensive work, and DIY attempts often fail to meet product performance standards due to problems such as uneven fiber distribution and improper curing, and may even pose safety hazards.

Equipment investment is the primary obstacle. GRC production requires specialized equipment such as forced-action mixers, spraying equipment, and vacuum dewatering devices, with a single set costing over one million yuan. Small mixers can hardly ensure uniform fiber distribution, and manual mixing easily causes fiber clumping. The curing stage requires a constant temperature and humidity environment, which DIY conditions cannot precisely control. Qinglong Group has introduced a fully automated production line from Germany and monitors process parameters in real time through sensors to ensure stable product quality.

Technical experience is crucial. The mix design of GRC requires deep knowledge of materials science, with precise calculations needed for fiber content, water-binder ratio, admixture selection, and more. The control parameters for each stage of the production process require long-term accumulated experience. Qinglong Group has a provincial-level engineering technology center and invests more than 5% of annual sales revenue in R&D—technical accumulation that DIY cannot match.

Quality risks cannot be ignored. When GRC is used in building envelope systems, its flexural strength must exceed 18 MPa, and its durability must meet a 50-year service life requirement. DIY products lack testing means and show large performance variability, which may cause safety accidents in engineering applications. Every batch of Qinglong Group's products undergoes third-party testing, with impact resistance exceeding 10 kJ/m², so quality is guaranteed. Users are advised to purchase from professional manufacturers, which both ensures quality and reduces overall costs.
