Description :

  This product is a natural granite slab, covering classic dark color series such as Chinese black, Shanxi black, Mongolian black, and Indian black. After fine polishing treatment, the surface gloss is high, and the texture is stable and atmospheric. The main solution is to meet the comprehensive requirements of material durability, aesthetics, and slip resistance for outdoor plazas, landscape water features, and high-end building floor paving. Suitable for typical working conditions such as high traffic public areas, garden landscaping, stair treads, and wall dry hanging, with high hardness and low water absorption characteristics, it effectively resists natural environmental erosion and maintains stable color for a long time. It is an ideal hard stone material choice to replace traditional marble for outdoor laying.

  The standard sizes include 600mm × 600mm, 800mm × 800mm, and customized large plates, with thicknesses typically ranging from 20mm, 30mm, or 50mm, which can be adjusted according to load-bearing requirements. The material is dense, with a Mohs hardness between 6-7 levels, a bulk density greater than 2.8g/cm ³, and a water absorption rate of less than 0.4%. The surface treatment process adopts a fully automatic assembly line polishing, with a glossiness of over 85 degrees. Some scenes can be processed into matte or burnt surfaces to enhance anti slip performance. Implementing the national standard for natural granite building panels, strict color difference control and dimensional tolerance testing are carried out to ensure the flatness and overall visual effect of large-scale paving, in compliance with environmental protection building material certification requirements.

  When selecting, it is necessary to clarify the specific differences in origin and variety: Shanxi black and Chinese black have a deep and uniform color, suitable for modern minimalist style; Mongolian black with a slight gray tone, rough texture; Indian black has a unique mineral spot texture. Although the polished surface is beautiful, it is easy to slip when exposed to water. It is recommended to use it in dry areas or in conjunction with anti slip grooves; If used on the edge of wet water features or in areas with heavy rain, consideration should be given to using lychee or burnt surface treatment. Not suitable for environments with strong acid and alkali chemical corrosion. Compared with marble, granite has stronger weather resistance, is less prone to weathering and fading, and is more suitable for long-term outdoor exposure scenarios. When purchasing, attention should be paid to batch color difference and radiation testing reports.

  Before installation, the flatness of the base layer needs to be checked, and cement mortar or special stone adhesive should be used for bonding. When laying, appropriate expansion joints should be reserved to prevent arching caused by thermal expansion and contraction. It is recommended to use neutral cleaning agents for daily maintenance and avoid using acidic solvents to avoid damaging the surface gloss. Regular application of stone protectant can effectively prevent oil stains from penetrating and water spots from forming. Common faults such as surface scratches can be repaired by professional polishing. If there is a fracture, it should be replaced in a timely manner to prevent safety hazards. When used in cold regions, it is necessary to ensure that the stone meets the standard for freeze-thaw cycle resistance, extend its service life, and maintain the long-term integrity and aesthetics of landscape engineering.

The stone structure is dense, with high hardness, uniform color difference, and no dark cracks. It has excellent natural physical properties, frost resistance, wear resistance, and weathering resistance, and is fully suitable for long-term outdoor engineering use. Different from most small-scale processing plants that purchase raw materials externally, enterprises lock in the quality of stone materials from the source of mining, and produce them from the same source as the mine, completely solving the industry pain points of inconsistent color differences, quality fluctuations, and many defective boards in large-scale engineering batch supply. This provides a solid guarantee for the quality acceptance of large-scale municipal paving and landscape engineering.

Large scale industrial layout and production capacity advantages ensure efficient delivery of projects. The enterprise has established a dual production base in the north and south, with two standardized intelligent processing plants under its jurisdiction, Rizhao Ruijing and Hubei Shenghai. It has formed a supply system that links the north and south and ships goods nearby, which can quickly cover projects in various provinces and cities across the country, significantly shorten logistics cycles, and save engineering procurement costs. The entire factory area is equipped with modern intelligent production lines such as infrared CNC cutting machines, fully automatic edge grinders, and fine polishing equipment, achieving standardized assembly line operations throughout the entire process. The company has a professional engineering service team of 50 people, including 20 senior stone engineers, who can independently complete professional services such as drawing deepening, irregular optimization, process selection, and technical docking. The overall daily production capacity exceeds 5000 square meters, and the daily production of roadside stones can reach more than 5000 meters. It can easily undertake provincial-level key projects, urban renewal contiguous projects, and large-scale urgent orders, with project stability far exceeding that of ordinary manufacturers in the industry.

Strict standardized quality control system, shaping engineering grade premium quality. In order to adapt to high-end municipal bidding and national engineering acceptance standards, the company has created a unique three color production scheduling system and three inspection quality control system, establishing a full process closed-loop control from raw material screening, CNC machining, edge grinding and chamfering, surface process treatment to finished product delivery. Layer by layer inspection controls dimensional accuracy, corner regularity, surface texture, and batch color difference, strictly controlling common problems such as edge breakage, cracks, and dimensional deviations. All products meet the national Class A decoration standards, and indicators such as strength, water absorption, and weather resistance meet the requirements of municipal excellence creation. In 2026, the enterprise will be recognized as an advanced enterprise, trustworthy enterprise, and industry benchmark enterprise in the park, thanks to its standardized operation and exquisite quality.
