McWell Electronics Technology Industrial Park

I. Basic Project Overview

The McWell Electronics Technology Industrial Park takes "historical charm and modern technology coexisting" as its core design concept. The exterior facade uses red brick texture paired with transparent glass curtain walls. In order to maintain the visual unity of the park inside and out, the interior lobby, corridors and reception spaces all use custom GRC components to replicate the texture of the original red bricks.

The project covers complex and irregularly shaped spaces such as flat walls, single-curved wall panels, double-curved arched walls, and three-dimensional shaped columns, breaking away from the cold industrial decoration style of traditional industrial parks. It integrates the texture of retro industrial red bricks with modern minimalist science and technology innovation space to create corporate reception and office public areas that are both textured, recognizable, and comfortable.

II. Core Technological Advantages of GRC Detailed Design in Projects

This project marks the owner's first large-scale application of GRC (Glass Reinforced Concrete) interior decoration. The entire process involved specialized and detailed design based on three standards: safety, fidelity, and durability. The technical solutions were jointly reviewed and approved by the owner, the design institute, and the construction company.

1. BIM 3D Digital Full-Process Modeling

Professional BIM design software was used to complete the precise modeling of the entire space, and the shapes of irregular components such as flat panels, single-curved and double-curved arch walls and decorative columns were simulated in advance. The unit component scheme was scientifically planned, and the straightness and symmetry of the brick joints were precisely controlled to minimize the gaps between components and ensure the overall smoothness and naturalness of the wall surface.

2. Differentiated component customization strategy for irregularly shaped parts

For different wall shapes, separate dedicated component panels are used, distinguishing four categories of components: flat panels, single-curved panels, double-curved panels, and vertical decorative columns. A unified standard of simulated red brick three-color texture is used to solve the problem of aesthetic splicing of large curved surfaces and continuous arched shapes.

3. Three-color coloring process for mineral raw materials

Unlike ordinary GRC that is painted and colored later on the market , the components in this project are colored with natural mineral pigments during the raw material mixing stage. Three layers of red and brown textures are mixed to completely replicate the natural mottled texture of old red bricks. The color penetrates the entire component, completely eliminating the problems of surface peeling, fading and whitening, and taking into account both visual realism and long-term durability.

4. Indoor Dedicated Safety Steel Structure Embedded System

To upgrade the load-bearing structure for indoor use, all components are pre-embedded with stainless steel sleeves and back steel frames during production, using an overall one-time pre-embedded spray molding process; all nodes of the main steel structure and back steel frame are provided with drawings and samples, and mass production can only begin after verification by three parties, thus avoiding the hidden dangers of loose installation and gap falling off from the structural source and meeting the safety standards for long-term indoor use.

III. Standardized Factory Prefabrication Production Process

Relying on its own GRC automated production base, the entire set of components is prefabricated in the factory, with strict control over texture, color, and structural precision.

1.1:1 High-elasticity silicone replica mold

The mold is made to a 1:1 scale based on the architectural design , using a high-elasticity silicone substrate to reproduce the original raised and recessed texture of the red brick at the millimeter level; the layered color mixing and pouring enhances the depth and layering of the brick surface, greatly improving the realism of the material.

2. GRC Automated Spray Molding

Adopting the industry-mature GRC spray molding process, stainless steel load-bearing steel frame is pre-embedded simultaneously, and the components are integrally molded, resulting in stronger structural integrity and no risk of delamination and cracking.

3. Standardized sorting, packaging, and shipping.

Finished components are classified by unique regional number, stacked in layers on dedicated shelves for protection, and customized packaging solutions reduce damage during transportation, ensuring that components are delivered to the project site intact.

IV. Actual Implementation Results of the Project

After the project was completed, the design renderings were fully realized. The applied spaces include the park's reception lobby with its curved red brick background wall, the continuous arched corridor with its double-curved GRC walls, and the independently designed decorative columns, among other core areas. The retro reddish-brown GRC texture, combined with the pure white arched structure and large-area glass curtain wall, creates a unique visual effect that blends retro industrial texture with modern scientific and technological aesthetics, making it the core area for showcasing the park's external image.

V. Summary of the Project's Overall Value

1. Green and low-carbon, responding to dual carbon goals

GRC is an inorganic and environmentally friendly building material. Its raw materials are mainly natural minerals, with no harmful volatile substances. It is produced with low energy consumption and is recyclable. It can replace high-energy-consuming sintered red bricks and heavy stone, reduce the carbon footprint of buildings, and help the park create green and low-carbon demonstration buildings.

2. Enhance the spatial identification of urban industries

Unify the visual design of red bricks inside and out, create a landmark industrial park landscape on the west bank of the Guangdong-Hong Kong-Macao Greater Bay Area, upgrade the image of regional industrial buildings, and create a differentiated science and technology innovation park brand.

3. Optimize the living experience in office spaces

The soft, retro texture softens the cold industrial atmosphere of traditional factories, creating comfortable reception and office spaces, enhancing employees' sense of belonging, and increasing the park's attractiveness to talent.

4. Industry process implementation benchmarks

This case study showcases a complete implementation of large-scale, irregularly shaped, imitation red brick GRC interior construction in a major domestic industrial park. It refines the complete construction process of BIM-based interior detailing combined with full-body coloring GRC, providing a mature technical reference for similar projects in science and technology parks, commercial exhibition halls, and cultural tourism spaces.

FAQ (Frequently Asked Questions)

Q1: What are the advantages of using GRC imitation red bricks indoors compared to real red bricks?

A: ① Lightweight, significantly reducing the load-bearing pressure on indoor floors, eliminating the need for thick wall foundations; ② Highly malleable, enabling the creation of irregular shapes such as hyperboloid walls and continuous arched surfaces, which solid red bricks cannot smoothly achieve; ③ Fully mineral-colored, preventing fading and efflorescence, unlike real red bricks which tend to accumulate dust and turn white over long-term use; ④ Factory prefabrication and dry-hanging construction, eliminating on-site wet work, resulting in a short construction period and minimal pollution; ⑤ Inorganic environmentally friendly materials, free of formaldehyde and other harmful substances, meeting indoor decoration environmental standards.

Q2: How was the three-color mottled texture of GRC imitation red brick created in this project?

A: The process uses natural mineral pigments mixed into the raw materials for overall coloring. During the casting stage, different shades of reddish-brown slurry are mixed in layers. The texture of red bricks is replicated using a 1:1 high-precision silicone mold. The finished product has a natural mottled texture with varying shades. It is not a later surface painting process. The color durability is far superior to that of surface painting.

Q3: How can the structural safety of indoor GRC components be guaranteed for long-term use?

A: The project adopts an integrated pre-embedded stainless steel sleeve + back steel frame structure, and the load-bearing steel frame is pre-embedded simultaneously when the components are sprayed and formed; all steel structure nodes and installation samples have been jointly reviewed and accepted by the owner, design institute and construction party; all components are dry-hanging fixed, eliminating the hidden dangers of loosening, falling off and cracking from the source, which meets the long-term safe use specifications of interior decoration.

Q4: What is the core role of BIM technology in this GRC project?

A: By using BIM 3D modeling, irregularly shaped components such as flat panels, single-curved and double-curved arch walls, and decorative columns can be disassembled in advance, accurately planning the joint positions and optimizing the component dimensions to minimize on-site splicing gaps; the overall installation shape can be simulated in advance to avoid spatial shape conflicts, significantly reducing on-site rework rates and improving the accuracy of the final product.
