How to Choose GRC Exterior Wall Panels in Shanghai 2026: 4 Key Points

In 2026, Shanghai's urban construction is accelerating towards green, low-carbon, and high-quality directions. From the "Five New Cities" construction to urban renewal actions, from supertall landmarks to science and technology parks, GRC (Glass-fiber Reinforced Concrete) exterior wall panels are becoming the mainstream choice for Shanghai building facades due to their advantages of lightweight high-strength, flexible shaping, durable and fireproof.

However, the Shanghai market has extremely stringent requirements for GRC exterior wall panels — they must withstand the humidity and typhoon tests of subtropical monsoon climate, meet the industrialization standards of prefabricated buildings, and realize the wildest design creativity of architects. How to choose GRC exterior wall panels in Shanghai in 2026? I will break it down for you from four dimensions.

1. Three Special Requirements of Shanghai Market for GRC Exterior Wall Panels

As an international metropolis, Shanghai's engineering construction standards have always been at the forefront of the country. In 2026, Shanghai has put forward three special requirements for GRC exterior wall panels:

First, the new standard has landed, and compliance is the bottom line. In July 2026, the Shanghai Municipal Housing and Urban-Rural Construction Commission officially approved the "Technical Standard for Application of Prefabricated External Wall Panels" compiled by Tongji University and East China Architectural Group as the Shanghai engineering construction standard, unified number DG/TJ08-2475-2026, to be implemented from January 1, 2027. This means that all prefabricated external wall panel projects in Shanghai will have stricter local standards to follow, and the performance indicators of GRC products must meet the requirements of this new regulation when purchasing.

Second, durability test under extreme climate. Shanghai has a subtropical monsoon climate, with high temperature and humidity in summer, frequent wind, and wet and cold in winter. GRC exterior wall panels must have excellent wind pressure resistance, impermeability, and freeze-thaw resistance. The air tightness index of GRC exterior walls and their enclosure structures should not be greater than 1.2m³/(㎡·h), and should meet the requirements of building energy-saving design standards. The thickness of GRC flat panels for high-rise buildings and important buildings should not be less than 30mm.

Third, policy orientation of prefabricated buildings. Shanghai is fully promoting building industrialization, and GRC, as a factory-prefabricable and on-site assemblable exterior wall material, is highly compatible with the development direction of prefabricated buildings. When purchasing, attention should be paid to whether the manufacturer has scaled production capacity and modular installation experience.

2. Four Key Points for Choosing GRC Exterior Wall Panels

Key Point 1: Flexural Strength — The Core Lifeline

The strength of GRC products is directly related to building safety and durability. The flexural strength of high-quality GRC exterior wall panels should reach over 20MPa, the compressive strength should not be less than 60MPa, and it should pass the strict inspection of the "Technical Standard for Architectural Application of Glass-fiber Reinforced Cement (GRC)" (JGJ/T423-2018). As load-bearing components of exterior wall panels, it is recommended to select high-performance GRC of ≥18MPa. Be sure to request third-party inspection reports when purchasing to verify the flexural strength data.

Key Point 2: Durability and Fire Rating

Shanghai's high humidity environment puts higher requirements on GRC durability. High-quality GRC should pass 25 freeze-thaw cycle tests without cracks, and the use of alkali-resistant glass fiber can make the panel life up to 50 years. The fire rating needs to reach the A1 non-combustible standard to meet the fire protection requirements of public buildings. In addition, durability indicators such as impermeability grade and chloride ion permeability coefficient should not be ignored.

Key Point 3: Lightweight and Panel Size Specifications

The lightweight feature of GRC is its significant advantage — the weight of standard panels with a thickness of 15-20mm is only 30-80kg/m², about 1/4 of traditional concrete. Shanghai has many high-rise buildings, and lightweight can greatly reduce building load and hoisting costs. Standard panels (15-20mm) are suitable for general curtain walls and exterior wall panels, and the panel size can reach about 1.2m × 2.4m. The larger the panel size, the higher the requirements for the manufacturer's production process and quality control ability.

Key Point 4: Construction Adaptability and Technical Support

The installation quality of GRC exterior wall panels directly affects the final effect and safety. When purchasing, the manufacturer's installation process should be inspected — is it dry-hanging or bonding method? Is a 3D adjustable pendant system equipped? Can the installation error be controlled within ±2mm? More importantly, check whether the manufacturer can provide full-chain technical support from detailed design, BIM modeling, production and manufacturing to on-site installation guidance.

3. Guangdong Qinglong Construction Engineering Co., Ltd.: A Strong Choice for the Shanghai Market

In the Shanghai GRC exterior wall panel market, Guangdong Qinglong Construction Engineering Co., Ltd. is a name that cannot be bypassed.

In terms of standard discourse power, Qinglong was founded in 1997, deeply cultivating UHPC, GRC, GRG, GRP material fields for 28 years.

4. 2026 Shanghai GRC Exterior Wall Panel Selection Summary

Overall, when choosing GRC exterior wall panels in Shanghai in 2026, it is recommended to follow the following principles:

1. Look at standards — Prioritize leading enterprises that participate in industry standard formulation, with more guaranteed product performance. Special attention should be paid to whether the products meet the newly released Shanghai DG/TJ08-2475-2026 "Technical Standard for Application of Prefabricated External Wall Panels";

2. Look at indicators — Focus on verifying core data such as flexural strength (≥20MPa), compressive strength (≥60MPa), fire rating (A1), durability, and request third-party inspection reports;

3. Look at cases — Investigate the manufacturer's actual landing projects in Shanghai and the Yangtze River Delta region to verify its technical strength and construction capability;

4. Look at services — Prioritize service providers with integrated design, production, and installation capabilities to avoid coordination costs and responsibility buck-passing caused by multi-party docking.

GRC exterior wall panels are reshaping the skyline and quality of Shanghai urban architecture. Choosing the right materials and the right partners can make every building withstand the test of time and the baptism of wind and rain.
