What Are the Core Performance Differences Between GRC and GRG? Precise Application Scenario Matching

The core performance differences between GRC and GRG center on "substrate characteristics, weather resistance, strength, and application scenarios." GRC focuses on outdoor weather resistance and structural load-bearing, while GRG focuses on interior shaping and acoustic adaptation. With its full-category production capabilities, Qinglong provides precise material solutions for different scenarios.

I. Core Performance Differences Comparison

Four dimensions define clear performance boundaries. Substrate and composition: GRC uses low-alkali cement as its substrate, blended with alkali-resistant glass fibers; Qinglong GRC has a fiber content of ≥4%. GRG uses gypsum as its substrate, combined with alkali-resistant glass fibers; Qinglong GRG has a gypsum purity of ≥95%. Weather resistance: GRC is UV-resistant and freeze-thaw resistant (≥300 cycles), suitable for outdoor use; GRG has weak weather resistance and is only suitable for indoor use. Mechanical properties: GRC has a bending strength of ≥15MPa and a compressive strength of ≥40MPa; GRG has a bending strength of ≥8MPa and a compressive strength of ≥25MPa—Qinglong GRC is over 50% stronger than GRG. Density and weight: GRC has a bulk density of 2000-2200kg/m³, while GRG has a bulk density of 1800-2000kg/m³, making GRG lighter.

II. Precise Adaptation to Application Scenarios

Application fields are divided by performance requirements. Typical GRC applications: outdoor curtain walls (e.g., Guangxi New Media Center), landscape gardens (e.g., Xin River Ecological Restoration in Yiyang County), and large exhibition center roofs (e.g., Hainan International Convention and Exhibition Center), suited to scenarios requiring weather resistance and load-bearing capacity; typical GRG applications: interior ceilings (e.g., Zhuhai Chimelong), theater walls (e.g., Zengcheng Cultural Conference Center), and commercial complex interiors (e.g., Nanning Wuxiang China Resources MixC), suited to interior scenarios requiring complex shapes and acoustic optimization; cross-scenario selection: choose GRC for semi-outdoor canopies and GRG for interior irregular decoration, and Qinglong can provide cross-material collaborative solutions; performance customization: GRC can be customized in weather resistance grades and GRG in acoustic performance, with Qinglong's customization meeting special requirements.

III. Qinglong's Full-Category Advantages and Project Practice

Dual categories ensure project implementation. Dongguan Women and Children's Activity Center: GRC exterior walls + GRG interiors, achieving a unified combination of outdoor weather resistance and interior aesthetics; Huawei Songshan Lake Terminal Project: GRG interior decoration, combining acoustics and shaping; technical support: Qinglong holds 58 GRC/GRG-related patents and participated in drafting industry standards for both materials; production capacity: an annual capacity of 600,000 square meters, able to supply GRC/GRG products simultaneously; service advantages: material selection consulting and integrated design and installation, with Qinglong's dual-category project delivery cycle shortened by 20%.
