Compressive ≥150MPa Thickness 20-30mm Weight -60% Lifespan 100+ years

Why Choose UHPC for Building Curtain Walls?

Modern building facade design increasingly pursues thinness, transparency, rich shapes, and durability. Traditional natural stone, ceramic panels, GRC panels, and ordinary concrete panels have limitations in thickness, weight, strength, and durability. UHPC, as a new facade material, combines ultra-high strength, ultra-thinness, excellent formability, and ultra-durability, making it the ideal choice for modern building facades.

Handan Chengyuan Technology supplies UHPC premix concrete, carefully formulated with special cement, silica fume, quartz powder, quartz sand, steel fibers, and high-range water reducer, with compressive strength ≥150MPa, flexural strength ≥25MPa, chloride ion diffusion coefficient <0.1×10⁻¹² m²/s, meeting high-quality facade requirements.

Types and Applications of UHPC Curtain Wall Panels

1. UHPC Flat Hanging Panel

UHPC flat hanging panel is the most basic form, with thickness 20-40mm and size up to 1.5m×3m or even larger. Compared with natural stone, UHPC flat panel is 60% lighter, 5 times stronger, has better durability, and the price is only 50%-70% of high-grade stone. The surface can be treated with various effects such as fair-faced concrete, sandblasting, polishing, and dyeing, capable of simulating the visual effects of various materials such as stone, metal, and ceramics. Suitable for building facades of office buildings, commercial complexes, and residences.

2. UHPC Shaped Hanging Panel

UHPC has excellent formability, capable of producing hanging panels of various complex shapes, including curved panels, folded panels, perforated panels, relief panels, and textured panels. The high fluidity of UHPC can perfectly replicate the fine texture of molds, with a minimum texture depth of 0.5mm. Shaped hanging panels can bring unique visual effects and artistic expression to building facades, and are a popular choice in modern architectural design. Suitable for cultural buildings, exhibition halls, commercial complexes, and landmark buildings.

3. UHPC Sunshade Louvers (Brise-soleil)

UHPC sunshade louvers are building components that combine decoration and functionality, effectively blocking direct sunlight, reducing building energy consumption, while creating rich facade light and shadow effects. UHPC sunshade louvers can be as thin as 15-20mm, with length up to 2-3m and cantilever length up to 1-1.5m, with sufficient strength and stiffness. Compared with metal louvers, UHPC louvers have better durability, lower maintenance costs, and richer shapes. Suitable for public buildings such as office buildings, schools, and hospitals.

4. UHPC Perforated Panels

UHPC perforated hanging panels form various perforated patterns by pre-embedding in molds or post-processing, combining decoration and light transmission. The ultra-high strength of UHPC allows perforated hanging panels to achieve a large perforation rate (up to 40%-60%) while maintaining sufficient structural strength. Perforated hanging panels can bring unique light and shadow effects and visual hierarchy to building facades, suitable for commercial buildings, cultural buildings, and parking buildings.

5. UHPC Stone-imitation Hanging Panel

UHPC stone-imitation hanging panels simulate the texture and color of various natural stones, including marble, granite, limestone, and slate, by incorporating colored aggregates, mineral pigments, or using special surface treatment processes. Compared with natural stone, UHPC stone-imitation hanging panels are lighter, stronger, more durable, have less color difference, and are more customizable, with the price only 50%-70% of natural stone. Suitable for facade decoration of various buildings.

6. UHPC Metal-texture Hanging Panel

UHPC metal-texture hanging panels simulate the visual effects and texture of metals (aluminum, copper, stainless steel, Corten steel, etc.) by incorporating metal powders on the surface, using special coatings or surface treatment processes. Compared with metal panels, UHPC metal-texture hanging panels have lower cost, better durability, do not rust, do not require frequent maintenance, and have richer shapes. Suitable for industrial-style buildings, commercial buildings, and cultural buildings.

Are UHPC Panels More Expensive or Cheaper Than Natural Stone?
From direct material cost perspective, UHPC panel price is equivalent to mid-range natural stone, 30%-50% cheaper than high-end natural stone (such as Italian marble, Spanish sandstone, etc.). But from full life cycle cost perspective, UHPC panels have obvious advantages: (1) Lightweight, reduces supporting structure cost and wall installation cost; (2) Durable, service life over 100 years, no need for regular maintenance; (3) Customizable, can achieve shapes and surface effects that natural stone cannot; (4) Stable supply, not affected by natural resources and market fluctuations.
What is the Minimum Thickness of UHPC Panels? Will They Break if Too Thin?
The minimum thickness of UHPC panels depends on element size, support conditions, and design loads. Generally: (1) Small panels (<1m²): thickness can be 15-20mm; (2) Medium panels (1-3m²): recommended thickness 20-30mm; (3) Large panels (>3m²): recommended thickness 30-50mm. Thanks to UHPC ultra-high flexural strength (≥25MPa) and steel fiber reinforcement, thin panels will not break under normal loads. However, structural calculations should be performed to determine appropriate thickness based on specific usage conditions.
Can UHPC Color and Surface Effect Be Customized?
Yes, UHPC has strong customizability. In terms of color: (1) Concrete body color can be adjusted by mixing inorganic mineral pigments (iron oxide series, chromium oxide series, etc.); (2) Gradient or multi-color effects can be achieved through special mixing techniques. In terms of surface effect: (1) Any mold texture can be replicated, including natural stone, wood, metal, sand texture, etc.; (2) Bare concrete, polished concrete, ground concrete effects can be achieved; (3) Functional surface coatings can be added, such as anti-fouling coating, anti-bacterial coating, heat-reflective coating.
How is the Fire Performance of UHPC Panels?
UHPC panels have excellent fire performance, classified as non-combustible material (Class A fire protection). Main advantages: (1) UHPC main raw materials are cement, quartz sand, silica fume, etc., all inorganic non-combustible materials; (2) At high temperatures, UHPC does not produce toxic gases or smoke, and does not melt or drip; (3) UHPC has good thermal spalling resistance, as steel fibers can constrain concrete thermal expansion and prevent spalling; (4) After standard fire testing, UHPC retains over 80% of its original strength. For building facades, UHPC is a safe and reliable material.
Do UHPC Panels Need Maintenance? What is the Service Life?
UHPC panel maintenance costs are extremely low, classified as "maintenance-free" building material. Main reasons: (1) UHPC porosity is extremely low (<5%), water absorption rate <1%, preventing penetration of water and harmful substances; (2) Chloride ion diffusion coefficient <0.1×10⁻¹² m²/s, 1/100 of ordinary concrete, excellent chloride corrosion resistance; (3) Freeze-thaw resistance >1000 cycles, suitable for cold regions; (4) Good resistance to UV radiation and thermal cycling, no color change or surface peeling over long term. UHPC service life exceeds 100 years, 2-3 times traditional facade materials. Under normal conditions, UHPC panels do not need special maintenance, only regular cleaning with clean water.
