Prefabricated Component House Decoration

Prefabricated components are widely used in house decoration, covering scenarios such as exterior walls, indoor ceilings, wall shapes, and artistic spaces. They offer advantages such as lightweight and high strength, efficient construction, and strong durability, making them an important choice for modern green decoration.

I. Material Types and Characteristics

1. GRC (Glass Fiber Reinforced Concrete)
   • Matrix and Reinforcement: Using cement mortar as the matrix, mixed with alkali-resistant glass fibers (AR glass fibers), it has an flexural strength 2-3 times that of ordinary cement mortar, with a thickness controllable to 1-2 centimeters.
   • Shaping and Surface Treatment: Formed through molds, it can replicate European-style carvings, new Chinese-style lines, or modern curved components; the surface can be treated to resemble stone, plain concrete, or painted colors to meet diverse design needs.
   • Lightweight Advantage: Weighing approximately 20-30 kilograms per square meter, it is only one-fourth the weight of dry-hung stone, eliminating the need to reinforce the main structure during old building renovations.
   • Durability: Properly cured GRC components can be used for decades in normal outdoor environments, with durability superior to wood decoration or plaster products.
2. GRG (Glass Fiber Reinforced Gypsum)
   • Curved Surface Shaping Capability: It can shape any curved surface, widely used in indoor ceilings, wall decorations, and artistic spaces, meeting designers' needs for complex forms.
3. UHPC (Ultra-High Performance Concrete)
   • Ultra-High Strength and Durability: With a compressive strength of 120-180 Mpa, it supports a maximum hollow-out rate design of 70%, suitable for building facades, landscape components, and ultra-thin curtain walls.
   • Surface Texture: It has a high finish and fine texture, capable of simulating the textures of different materials such as stone and metal, meeting creative design needs.

II. Construction Efficiency and Environmental Advantages

• Standardized Production and Assembly: Prefabricated components are produced in factories in a standardized manner and assembled on-site, shortening the construction period by more than 50% compared to traditional methods, reducing on-site dust and noise by more than 80%, and reducing carbon emissions by more than 40%.
• Typical Process: Taking GRC as an example, the production process includes mold making, material spraying and forming, 7-day curing, surface treatment, and then transportation to the site for fixation through embedded parts and keels.

III. Policy and Market Drivers

• Policy Support: The 2026 "15th Five-Year Plan for Carbon Peaking Action" clearly supports the large-scale development of prefabricated buildings. The Ministry of Housing and Urban-Rural Development's "Opinions on Improving Housing Quality" promotes prefabricated decoration technology, and many localities have issued technical guidelines to drive industry upgrades.
• Market Demand: Old building renovations account for more than 55%, with over 20 billion square meters of old residential buildings across the country entering the renovation cycle. GRC has become the preferred choice for exterior wall renovations due to its cost-effectiveness; UHPC prefabricated components are priced at 260-300 yuan per meter, with a total supply of 100,000 meters.

IV. Material Selection Considerations

• GRC must use alkali-resistant glass fibers (AR glass fibers) to avoid corrosion and cracking caused by ordinary glass fibers in the alkaline environment of cement.
• Choose reputable manufacturers and prioritize products that provide purchase vouchers and test reports to ensure material compliance.
• Balance effects and budget according to design needs, reasonably selecting materials such as GRC, GRG, or UHPC.
