What is the density range of GRC material? What are its advantages compared to natural stone?

GRC density is typically 1800-2200kg/m³, with a surface density of 30-50kg/㎡ (at 20mm thickness). Compared with natural stone (density 2600-2800kg/m³, surface density 50-70kg/㎡), it is 40%-50% lighter, 3-5 times stronger, and offers greater design flexibility.

In a super high-rise project in Shenzhen, GRC curtain walls (surface density 35kg/㎡) were used to replace stone (surface density 60kg/㎡), reducing structural load by 40% and saving 15% of the main structure cost. Meanwhile, GRC can achieve complex curved surfaces that are difficult to process with stone, providing greater scope for architectural design. Evaluation after 5 years of use showed that GRC maintenance costs are 60% lower than stone, with significant overall benefits.

Lightweight Advantages

40%-50% lighter, reducing structural load; easy to transport and install, improving efficiency; lowering foundation costs, saving investment. These advantages are evident.

Strength Performance Comparison

Flexural strength of 18-25MPa, 3-5 times that of stone; impact strength of 15-25kJ/㎡, 5-8 times that of stone; these properties enhance safety.

Design Capability Advantages

Complex shapes such as double-curved surfaces can be created; ultra-thin designs (minimum 3mm) are achievable; these advantages expand creative possibilities.

Overall Benefits Analysis

Initial investment is comparable to premium stone; maintenance costs are 60% lower; service life reaches up to 50 years. These benefits are significant.

GRC offers clear overall advantages. Qinglong GRC fully leverages the material's characteristics to create maximum value for customers.
