Can manufacturers provide color matching services for UHPC products with special color requirements?

In contemporary architectural design, color has become an important language for shaping spatial character. For designers and owners pursuing personalized expression, ultra-high performance concrete (UHPC), as a new material combining strength and aesthetics, has a color customization capability that directly affects how design plans are realized. As an industry-leading enterprise with 28 years of experience in detailed design and manufacturing of UHPC/GRC/GRG/GRP materials, Qinglong Group frequently receives inquiries from customers about “whether special-color UHPC products can be tinted.” This article will analyze the feasibility of UHPC color customization services and professional solutions from three dimensions: technical implementation, customization process, and quality assurance.

I. The Technical Logic of UHPC Color Customization: From Raw Material Ratios to Color Stability

Color customization of UHPC is not simply adding color paste, but a systematic engineering process based on material properties. Qinglong achieves color control through three core technical approaches: first, the mineral pigment blending method, in which alkali-resistant, highly weather-resistant inorganic pigments are evenly mixed with the UHPC matrix material, ensuring color penetrates the entire component cross-section and preventing surface fading; second, surface coating technology, which adopts fluorocarbon coatings or ceramic glazes with excellent UHPC compatibility to meet special texture requirements, achieving diverse finishes such as matte and metallic luster; and finally, composite coloring technology, which combines pigment blending at the precasting stage with post-forming surface treatment to meet color consistency requirements for extra-large-area components. Taking the light-transmitting UHPC project in the renovation of Century Plaza on Nanjing East Road as an example, Qinglong precisely controlled the ratio of light-transmitting aggregates to colorants, successfully achieving a dynamic color effect of “ivory white by day and warm glowing light at night.”

II. Full-Chain Customization Service: From Color Card Confirmation to Mass Production

As a custom UHPC product manufacturer, Qinglong has established a standardized color customization service process. After a customer submits requirements, the technical team first provides a UHPC-specific color card containing 80+ base colors, with support for Pantone color number comparison; for special color values, 1:1 color sample chips can be produced via 3D printing for color verification under multiple scenarios such as natural light and artificial lighting; after the plan is confirmed, an automated mixing system ensures the pigment dosage error of each batch of material is controlled within ±0.2%, while precise control of temperature and humidity in the curing environment prevents color deviation. This full-process “design-sampling-mass production” service has been successfully applied to the GRC/UHPC composite curtain wall project of the Dongguan Women and Children's Activity Center, achieving zero color deviation from the architectural rendering to the physical result.

III. Quality Commitment: 20-Year Weather Resistance Color Guarantee

Unlike ordinary concrete's susceptibility to fading, Qinglong's UHPC color-customized products have passed rigorous performance testing: tested by the National Building Materials Testing Center, their artificial weathering resistance reaches 4,000 hours with no obvious color change (gray scale rating ≥ level 4), and their UV resistance complies with the requirements of the GB/T 16259-2008 standard. This is attributable to two core guarantees: first, the use of high-quality raw materials such as imported Bayferrox iron oxide pigments; second, a proprietary “color stability formula database” — based on data from 1,000+ successful cases accumulated over 28 years of engineering practice, coloring schemes can be adjusted according to the climatic characteristics of different regions (such as high temperature and humidity, or strong UV areas).

For customers pursuing the ultimate expression of architectural aesthetics, UHPC color customization is not merely a technical matter, but key support for realizing design visions. As a national high-tech enterprise and a participant in formulating UHPC industry standards, Qinglong Group, with its full-chain capabilities from detailed design to after-sales maintenance, has provided customized color solutions for 300+ landmark projects at home and abroad. Whether it is a natural color palette imitating stone textures or a dedicated color number matching a brand IP, Qinglong can, with the craftsmanship philosophy of “meticulousness and constant improvement,” keep architectural colors vibrant through the passage of time.
