Explore our premium selection of oxide pigments and high-performance color solutions formulated specifically for the construction and concrete coloring industries.
Concrete is fundamentally a highly alkaline, harsh environment. To color concrete surfaces permanently, pigments must withstand severe chemical exposure and environmental elements. Unlike organic dyes, which quickly degrade under UV light and alkaline conditions, synthetic and natural iron oxide pigments (Fe₂O₃, Fe₃O₄, FeOOH) are the industry standard due to their outstanding stability.
Iron oxides remain completely stable when mixed into high-pH cementitious matrices, preventing color fading or chemical breakdown.
Inorganic pigments absorb ultraviolet radiation without structural changes, ensuring permanent color retention outdoors.
Excellent particle size distribution allows for high tinting efficiency, requiring lower dosage rates for deep color saturation.
Modern synthetic iron oxide pigments are manufactured via controlled chemical synthesis, yielding uniform particle sizes and shapes. This uniformity translates directly into consistent shade matching, batch after batch. Whether formulating deep reds, rich ochres, or dark carbon-infused blacks, synthetic iron oxides offer predictable dispersion properties within concrete slurry, preventing streaks and ensuring a uniform surface appearance.
Tianjin Xiangrui Dyestuff Co., Ltd., together with its subsidiary Tianjin Xiangrui International Trading Co., Ltd., was established in 1998 and 2021 respectively. The company is located in Dasi Industrial Park, Xiqing Economic Development Area, Tianjin, China, and currently employs several hundred staff members.
With over two decades of industry leadership, we have integrated state-of-the-art production technologies to serve the global construction and chemical coloring markets.
The global demand for colored concrete is witnessing unprecedented growth, driven by rapid urbanization, modern architectural designs, and the expansion of infrastructure networks. Municipalities and commercial developers are shifting away from plain grey concrete in favor of colored pavements, walkways, and public plazas that enhance aesthetic values and improve community branding.
Integral coloring using iron oxide pigments is highly cost-effective over the lifecycle of a structure. Unlike surface paints or coatings that peel, crack, and require frequent reapplication, integrally colored concrete embeds the pigment throughout the entire matrix. Even if the surface chips or undergoes heavy abrasive wear, the color remains intact, drastically lowering maintenance costs for commercial properties and public infrastructure.
From a supply chain perspective, China remains the leading global manufacturer of synthetic iron oxides. Companies like Tianjin Xiangrui play a vital role by offering high-purity pigments that meet rigorous international quality standards. The ability to supply bulk quantities consistently ensures that large-scale infrastructure projects—such as colored highway lanes, airport runways, and major residential developments—proceed without color deviation or supply disruptions.
Xiangrui specializes in the manufacture and supply of a wide range of different dyes, pigments, chemical auxiliaries, and intermediates, which are widely applied in industries such as textiles, papermaking, leather, coatings, inks, plastics, rubber, aluminum, cosmetics, and agriculture.
With an annual production capacity of approximately 18,000 tons, Xiangrui is able to provide stable and reliable supply to customers worldwide, bridging the gap between advanced chemical synthesis and practical industrial applications.
Oxide pigments are utilized across diverse applications in the modern construction sector. Understanding these scenarios allows architects and engineers to select the optimal coloring method and pigment dosage.
In large-scale public plazas, decorative walkways, and streetscapes, pigments are added directly to the ready-mix truck or batch plant. This ensures complete dispersion throughout the concrete mix. Typical dosage rates range from 1% to 6% based on the weight of the cementitious materials. The exact ratio determines the color intensity, from soft pastels to deep, saturated primary tones.
Precast panels, structural blocks, and concrete roof tiles demand highly precise color replication. Factory-controlled conditions allow for automated pigment dosing systems (liquid slurry or granular forms). This minimizes human error, resulting in uniform panels that fit seamlessly together on-site. The durability of iron oxides ensures that these high-exposure facades maintain their aesthetic appeal for decades under harsh weathering.
Stamped concrete replicates high-end materials like stone, brick, or slate. By combining integral oxide pigments with contrasting dry-shake color hardeners and release agents, installers achieve realistic, multi-toned textures. The base color provides depth, while the secondary accent colors highlight the stamped grout lines and surface textures, creating highly durable and visually stunning driveways, pool decks, and patio surfaces.
After years of continuous development, Xiangrui has established a fully integrated operation covering research and development, production, sales, and after-sales technical support. Supported by advanced manufacturing facilities, experienced R&D professionals, and a strict quality control system, we are committed to delivering products with consistent quality and performance.
Owing to superior product quality, professional service, and competitive pricing, Xiangrui has grown into one of the leading dyestuff manufacturers in North China, with products well recognized both in the domestic market and in overseas markets.
Our state-of-the-art facilities ensure high-volume output with rigorous quality checks at every step of the synthesis process.
As the construction industry shifts toward sustainable practices, the development of oxide pigments is keeping pace. Key innovations focus on reducing the carbon footprint of concrete coloring while introducing smart functionalities that combat urban challenges.
Urban areas suffer from the "Urban Heat Island" (UHI) effect, where dark pavements absorb solar radiation and raise ambient temperatures. Modern oxide pigment engineering has led to the development of "cool pigments" that reflect near-infrared (NIR) radiation. These pigments allow dark colored concrete surfaces to remain significantly cooler under direct sunlight, lowering energy consumption in surrounding buildings and improving urban microclimates.
Manufacturers are increasingly utilizing recycled iron sources, such as scrap metal byproducts, to synthesize iron oxides. By integrating circular economy principles, the carbon footprint of pigment production is reduced. Furthermore, these pigments are fully compatible with low-carbon concrete formulations, including geopolymers and high-volume fly ash or slag concrete mixes, supporting green building certifications like LEED.
In the digital age, matching custom colors across different cement types (white cement vs. grey cement) has historically been a challenge. The integration of AI-driven color matching software allows manufacturers and batch plants to analyze the mineral composition of raw cements and predict the exact dosage of oxide pigments needed to achieve a target shade. This reduces material waste and speeds up project execution times.
