About
Country and Quarry Origin
San Bao Red Granite, commonly identified by the Chinese stone code G563, is quarried in Cenxi City, Wuzhou, Guangxi Province, China.
Texture
San Bao Red Granite has a dense, compact and crystalline granular texture. The mineral grains are generally fine to medium in size and are closely interlocked, producing a solid surface with good structural stability. The stone can achieve a smooth, glossy appearance when polished, while flamed, bush-hammered and sandblasted finishes create a rougher, more slip-resistant texture.
Pattern and Veining
The stone features a light red, peach-red or pinkish-red background, mixed with cloud-like white areas, grey mineral grains and scattered black spots. Some slabs contain irregular white and dark streaks, while others display a more uniform speckled pattern. It normally has no strong directional veining, making it easy to match for flooring, wall cladding and large construction projects. Natural variations in color, grain concentration and white markings should be expected between quarry blocks.
Durability
Durability
San Bao Red Granite offers good compressive strength, abrasion resistance, weather resistance and dimensional stability. Its relatively low water absorption helps reduce moisture penetration and supports both interior and exterior applications. It is commonly used for flooring, stairs, wall cladding, façades, paving stones, kerbstones, countertops, monuments and landscape projects.
Representative technical values include:
Density: approximately 2,630 kg/m³
Water absorption: approximately 0.24%
Compressive strength: approximately 156.6 MPa
Flexural strength: approximately 10.0 MPa
These figures are indicative values rather than guaranteed specifications. Actual performance can vary according to the quarry section, block selection, surface finish, thickness and testing method. Project-specific laboratory testing is recommended for major engineering applications.
Acid Resistance
San Bao Red Granite has good resistance to brief contact with ordinary weak household acids and is significantly less acid-sensitive than marble, limestone or travertine. However, it should not be described as completely acid-proof. Prolonged exposure to acidic cleaners may affect certain trace minerals, surface sealers or the gloss of a polished finish.
Hydrofluoric-acid-based products are especially dangerous because hydrofluoric acid attacks silicate minerals and can damage granite. Neutral-pH stone cleaners should therefore be used for regular maintenance, and vinegar, strong acidic detergents and aggressive rust removers should be avoided.
Acid Sensitivity
San Bao Red Granite G563 is a durable Chinese red granite distinguished by its warm pink-red background, white cloud-like markings and scattered grey-black mineral grains. Its consistent granular appearance, low water absorption and strong mechanical performance make it suitable for residential, commercial, municipal and landscaping projects. Proper sealing and neutral-pH maintenance will help preserve its color and surface finish over long-term use.
