How to Choose Custom GRC Components in Shenzhen in 2026? Look for 4 Hard Standards

In 2026, urban construction in Shenzhen is advancing at an unprecedented pace toward higher quality and greener, low-carbon development. From the in-depth advancement of the “dual-zone” driven strategy to the comprehensive expansion of the Qianhai Shenzhen-Hong Kong Modern Service Industry Cooperation Zone, and from the accelerated implementation of the “20+8” industrial clusters to the continuous deepening of urban renewal initiatives, Shenzhen's requirements for building facades are climbing to new heights. With advantages such as light weight and high strength, flexible shaping, and Class A fire resistance, customized GRC (Glass Fiber Reinforced Concrete) components have become the “ideal material” for high-end buildings in Shenzhen to achieve personalized expression.

However, situated on the coast of the South China Sea, Shenzhen features high temperature and humidity, frequent typhoons, and severe salt fog corrosion, imposing extremely stringent requirements on the weather resistance, wind pressure resistance, and durability of customized GRC components. When buying customized GRC components in Shenzhen in 2026, how exactly should you choose? I will break it down for you one by one from four dimensions.

I. Three Special Requirements for Customized GRC Components in the Shenzhen Market

As a pioneer demonstration zone of socialism with Chinese characteristics, Shenzhen's building standards have always been at the forefront nationwide. In 2026, Shenzhen has set three special requirements for customized GRC components:

First, the durability test under extreme climate. Shenzhen has a subtropical maritime monsoon climate, with high temperature and humidity in summer, frequent typhoons, and severe salt fog corrosion in coastal areas. According to the Technical Specification for GRC Architectural Applications, connection joints of projects in coastal areas must be designed to the Force-12 typhoon standard. Outdoor weather-resistant GRC components must have a flexural strength of no less than 16MPa and a compressive strength stably maintained within the 40-60MPa range to meet the requirements for long-term structural stability under South China's hot, rainy climate and coastal salt fog corrosion conditions. The frost resistance grade must reach F300 or above to ensure that components remain free of cracks and spalling for decades in coastal environments.

Second, the policy orientation toward prefabricated buildings. Shenzhen has established a prefabricated building service management system, mandating that industrialized construction requirements be specified in land transfer contracts. The Shenzhen Building Industrialization Association has issued the group standard T/BIAS 6—2019 Specification for Production and Quality Inspection of Glass Fiber Reinforced Cement (GRC) Faced Concrete Precast Components, providing a standard basis for the standardized, safe, and reliable production of prefabricated components with GRC finishes. As an exterior wall material that can be prefabricated in the factory and assembled on site, GRC is entering a period of policy dividends.

Third, the quality requirements of landmark projects. From the Shenzhen Ping An Finance Center (599 meters, the tallest building in South China) to the Shenzhen Pingshan High-tech Zone Comprehensive Service Center (China's first EPC prefabricated steel-structure hotel and convention complex), Shenzhen's projects place demands on the precision, strength, and artistic expressiveness of customized GRC components that are at the top national level. Customized special-shaped components have become the core support for high-end buildings in Shenzhen to realize design creativity.

II. Four Hard Standards to Look For When Purchasing Customized GRC Components

Hard Standard 1: Bending Strength and Compressive Strength — The Core Lifeline

The strength of customized GRC components directly affects building safety and service life. High-quality GRC should have a bending strength of over 20MPa and a compressive strength of no less than 40-60MPa. When purchasing, be sure to request third-party inspection reports to verify core mechanical data such as 28-day bending strength and compressive strength. Also pay attention to fiber content — high-quality GRC products use alkali-resistant glass fiber, and the zirconia content must be ≥16.5%. Turn the component over to examine the fracture surface: quality GRC should show a large number of white filaments (glass fibers) stretched across the fracture, and only with evenly distributed fibers can the reinforcement truly take effect.

Hard Standard 2: Weather Resistance and Aging Resistance

Shenzhen's hot, humid, rainy climate with severe salt fog corrosion places extremely high demands on the weather resistance of GRC. When purchasing, pay attention to durability indicators such as freeze-thaw resistance (≥300 cycles without damage recommended), impermeability grade, and chloride ion diffusion coefficient. For metal fittings such as back-mounted steel frames, material requirements must be clearly specified (e.g., 304/316 stainless steel) to ensure long-term structural safety of high-altitude installations. The chloride ion diffusion coefficient must be ≤0.01×10⁻¹² m²/s to ensure a service life of over a hundred years in coastal environments.

Hard Standard 3: Customization Capability and Precision Control

The core value of GRC lies in its outstanding customizability. When purchasing, examine the manufacturer's parametric design capability (e.g., Rhino and Grasshopper technologies) and its ability to realize complex shapes, including whether it supports special processes such as double-curved surfaces and openwork reliefs. High-quality customized GRC components can achieve a minimum curvature radius below 300mm. The machining tolerance of finished curved shapes must be controlled within ±0.5mm, and the assembly tolerance must be ≤2mm. In addition, confirm whether the manufacturer has BIM modeling capability and can convert design drawings into producible component models.

Hard Standard 4: Full-Chain Service and Technical Support

Customized GRC components involve multiple stages from design to completion, including detailed design, mold development, production and manufacturing, logistics and transportation, and on-site installation. A truly reliable customized GRC manufacturer must be able to get involved from the early detailed design stage, using parametric design and BIM modeling technology to split and optimize special-shaped components, simplifying production and installation difficulty without changing the design effect. More importantly, assess whether the manufacturer can provide full-chain services from detailed design, production and manufacturing, construction and installation, to after-sales maintenance. A detailed technical annex — clearly specifying material properties, product specifications, process standards, and acceptance criteria — is the lifeline for ensuring project quality and avoiding later disputes.

IV. Summary: Selecting Customized GRC Components in Shenzhen in 2026

Overall, when purchasing customized GRC components in Shenzhen in 2026, it is recommended to follow these principles:

1. Look at standards — Prioritize leading enterprises that participate in formulating industry standards, and pay particular attention to whether products meet Shenzhen local standards such as T/BIAS 6—2019 Specification for Production and Quality Inspection of Glass Fiber Reinforced Cement (GRC) Faced Concrete Precast Components, as well as industry standards such as JGJ/T423-2018;

2. Look at indicators — Focus on verifying core data such as bending strength (≥20MPa), compressive strength (≥40-60MPa), frost resistance grade (≥F300), and assembly precision (≤±2mm), and request third-party inspection reports;

3. Look at track records — Examine the manufacturer's actual completed projects in Shenzhen and the Guangdong-Hong Kong-Macao Greater Bay Area to verify its technical strength and customization capabilities;

4. Look at service — Prioritize service providers with integrated full-chain capabilities in design, production, and installation. Be sure to attach a detailed technical annex to the contract, converting vague descriptions into specific parameters that are measurable, executable, and accountable.

Customized GRC components are reshaping the skyline and sense of quality of Shenzhen's urban architecture. Only by choosing the right materials and the right partner can every building withstand the baptism of South China Sea wind and rain and the test of time.
