Product Overview


Quarried from select global deposits renowned for superior quality, these slabs undergo precision polishing to achieve a mirror-like finish that enhances their inherent mineral patterns. Compliant with ASTM C18 standards for dimension stone, our indoor granite slabs meet rigorous criteria for strength, uniformity, and surface quality. With a service life exceeding 25 years under normal conditions, these slabs represent a long-term investment in both aesthetics and functionality, adding enduring value to any interior space.


Key Features


Large-Format Aesthetic Advantages

The 300x600mm dimensions create fewer grout lines than smaller tiles, resulting in a seamless, expansive look that visually enlarges interior spaces. This modern format minimizes visual interruptions, allowing the natural beauty of granite's unique veining and color variations to take center stage. The larger surface area creates a sense of luxury and sophistication, making these slabs particularly popular for open-concept living areas and contemporary designs. Despite their substantial size, the slabs maintain manageable weight for professional installation, ensuring versatility across various interior applications from residential foyers to high-end retail spaces.


Superior Surface Durability

Indoor granite slabs boast exceptional hardness rating 6-7 on the Mohs scale, providing superior resistance to scratches, dents, and daily wear. This hardness ensures the polished surface remains pristine even in high-traffic areas such as hallways, kitchens, and commercial lobbies subjected to constant foot traffic and furniture movement. The slabs exhibit excellent resistance to impact from dropped objects, a critical advantage for family homes and busy commercial environments. Unlike synthetic flooring materials, granite's durability increases with proper maintenance, maintaining its polished appearance for decades without significant degradation.


Stain Resistance and Easy Maintenance

Our polished granite slabs feature a low porosity of ≤0.5% that minimizes liquid absorption, providing inherent resistance to common indoor stains from food, beverages, and household chemicals. This non-porous surface simplifies routine maintenance—regular cleaning requires only mild detergent and water, with no need for specialized cleaners. A single application of penetrating sealer upon installation, followed by resealing every 3-5 years, further enhances stain resistance and simplifies care. The smooth polished surface prevents dust accumulation and allows for effortless cleaning, making these slabs ideal for environments where hygiene is a priority.


Thermal Stability and Comfort

Granite exhibits excellent thermal stability, maintaining consistent temperature properties that contribute to comfortable indoor environments. Unlike ceramic tiles that can feel cold underfoot, granite retains ambient warmth, enhancing comfort in living spaces. The material's low thermal expansion coefficient minimizes dimensional changes with temperature fluctuations, preventing cracking or loosening over time. This stability makes granite slabs suitable for installation over radiant heating systems, providing efficient heat distribution while maintaining structural integrity—a valuable feature for luxury residential and hospitality applications.


Applications


Residential Interior Spaces

In residential settings, 300x600mm granite slabs transform living spaces with enduring elegance. They create stunning kitchen floors that complement cabinetry and countertops, providing a cohesive look while withstanding cooking activities. Living room and dining room installations benefit from the slabs' large format, creating a sophisticated foundation for furniture arrangements. Entryways and foyers make memorable first impressions with granite's natural beauty, offering a durable surface that handles heavy foot traffic from outside. Bedroom sanctuaries utilize these slabs for their warm, natural appearance and easy maintenance, particularly in en-suite bathroom transitions where moisture resistance is valuable.


Commercial and Hospitality Environments

Commercial spaces leverage these granite slabs to convey quality and luxury to clients and visitors. High-end retail stores use them to create inviting shopping environments that reflect brand prestige while withstanding heavy customer traffic. Hotel lobbies and reception areas benefit from the slabs' elegant appearance and durability, maintaining a pristine look despite constant use. Restaurant dining rooms and cafes utilize granite flooring to create upscale atmospheres that complement culinary experiences, with the material's stain resistance handling occasional food spills. Office buildings specify these slabs for elevator lobbies and common areas, combining professional aesthetics with long-term performance.


Specialized Indoor Applications

Beyond standard flooring, 300x600mm granite slabs excel in specialized interior applications. They create striking accent walls in feature rooms, adding texture and visual interest to contemporary designs. Custom staircase treads benefit from granite's durability and slip resistance when properly finished, combining safety with elegance. Commercial restrooms utilize the slabs' moisture resistance and easy cleaning properties, maintaining a premium appearance in high-usage facilities. Exhibition spaces and museums employ granite flooring to provide a neutral, durable foundation that complements displayed artifacts while handling large crowds during events.


Storage Guidelines


Proper Storage Conditions

Store 300x600mm polished granite slabs in a climate-controlled indoor facility protected from extreme temperature changes and direct sunlight. Maintain a consistent humidity level between 40-60% to prevent natural stone from absorbing excess moisture or drying out. Place slabs on sturdy wooden pallets elevated at least 150mm above the floor, ensuring air circulation beneath and around stored materials. Use non-abrasive separators between individual slabs to prevent surface scratching and allow for proper ventilation. The storage area should be clean and free from dust, dirt, and chemical contaminants that could stain or damage polished surfaces.


Handling Recommendations

Always handle granite slabs with at least two people per slab, using proper lifting techniques that distribute weight evenly. Employ suction cup lifting tools rated for ≥200kg capacity when moving individual slabs to reduce manual strain and prevent dropping. Never drag slabs across any surface, as this can damage edges and polished finishes. Prior to installation, inspect each slab for shipping damage and sort them by color variation to ensure a balanced appearance in the final layout. Acquire 5-8% additional material beyond project requirements to account for cutting waste, fitting around obstacles, and potential future repairs.


Preparation Before Installation

Allow slabs to acclimate to the installation environment for 48-72 hours before installation, ensuring temperature equilibrium with the space. Clean all slab surfaces with a neutral pH stone cleaner before installation to remove any storage dust or residues that could affect adhesive bonding. Store slabs in the same room where they will be installed to prevent thermal shock during placement. Handle slabs with clean gloves to prevent oil transfer from hands to polished surfaces, which can create difficult-to-remove stains after installation. By following these storage and handling procedures, you ensure the granite slabs maintain their pristine condition until they are permanently installed.
