As a trusted supplier of Super Grey Granite, we are committed to delivering excellence, ensuring your vision is realized with the highest quality natural resources available.
Super Grey Granite is a dense, igneous rock renowned for its exceptional hardness and uniform coloration. Geologically, it is a true biotite granite, formed from cooling magma deep within the earth, which gives it a granular and crystalline structure. Unlike softer stones that may wear down over time, this material is built to endure. In the market, it is sometimes referred to by specific trade names depending on the quarry (often in central Iran), but it is universally recognized for its consistent grey background. It is a preferred material for construction projects requiring a balance of aesthetic neutrality and extreme structural resilience.
The structural integrity of Super Grey Granite makes it one of the most durable options for modern construction. Its physical makeup is characterized by high density and low water absorption (commonly ≤0.5% by mass), meaning it resists cracking and moisture damage effectively. This stone typically boasts a high compressive strength (often ~150–220 MPa), allowing it to support heavy loads without compromising its form. Flexural strength for comparable greys typically ranges ~10–20 MPa, and the material shows excellent abrasion resistance. Whether used for foundations, exterior paving, or structural cladding, its measurable attributes, such as bulk density and porosity, consistently meet the demands of rigorous engineering standards.
This stone is primarily composed of quartz and feldspar minerals, which provide its signature hardness. The texture is typically granular with a tight interlocking crystalline structure. You will often find small amounts of mica (biotite) or amphibole, which add subtle dark depth to the matrix without compromising the overall homogeneity of the stone.
The dominant hue is a sophisticated, medium-to-dark grey that remains consistent across large surfaces. Unlike marble, it does not feature wild or chaotic veining. Instead, it presents a uniform, salt-and-pepper pattern with subtle tonal variations, providing a clean and contemporary look that is highly sought after in modern architecture.
Typical bulk density is ~2.63–2.75 g/cm³. Apparent porosity is generally very low (often <1%), resulting in a water absorption rate commonly ~0.1–0.3%. This tight structure means there are very few open pores, making the stone naturally resistant to liquid penetration and freeze-thaw damage.
Scoring about 6–7 on the Mohs scale, this material is highly resistant to scratching. It possesses high compressive and useful flexural strength, meaning it can withstand significant weight and pressure. This inherent toughness makes it suitable for areas that experience heavy mechanical stress or high foot traffic.
The stone is generally very clean, with few naturally occurring defects like large clay seams or weak points. While microscopic fissures can exist in any natural stone, this grade is selected for its structural continuity. Oxidation spots or significant inclusions are infrequent in first-choice selections, helping the material maintain integrity during cutting and installation.
Visually, Super Grey Granite offers a sleek, industrial elegance that works beautifully in contemporary designs. Its appearance is consistent, avoiding the unpredictable variations often found in other natural stones. This reliability in look allows designers to plan large spaces with confidence, knowing the color will flow seamlessly from one area to another. Beyond looks, the stone is chemically stable and performs well under stress. It does not react negatively to common environmental factors, making it a safe choice for varied climates. The surface finish can be tailored to enhance its natural grey tones, ranging from deep polish to matte.
When polished, the stone achieves a high gloss, reflecting light beautifully to create a mirror-like depth. It also responds exceptionally well to honed or brushed finishes, which soften the color to a matte grey. Its semi-translucent quartz particles can catch the light, adding a subtle sparkle to the surface.
In a polished state, the surface is glass-smooth and cool to the touch, offering a premium feel. If a textured finish is applied, such as flaming, leathering, or bush-hammering, the stone takes on a tactile, non-slip quality. Even with texture, the stone remains robust, without the micro-pitting seen in softer materials.
This granite demonstrates excellent resistance to ultraviolet light, meaning its grey color will not fade even after years of direct sun exposure. It is also highly resistant to freeze-thaw cycles, preventing cracking in cold climates. Properly textured surfaces provide reliable slip resistance for exterior walkways.
Chemically, this stone is silicate-based and contains very little calcium carbonate, making it far more resistant to acids than calcitic stones. Unlike marble, it will not etch immediately if exposed to lemon juice or vinegar. However, prolonged exposure to strong acids can still impact the surface sealant or minor mineral inclusions.
We understand that different projects require specific formats, and this granite is available in a wide range of dimensions. The quarry yields large, shapely blocks, which allows for the production of expansive slabs and varied tile sizes. Whether you need standard flooring tiles or massive panels for wall cladding, the material can be processed to meet those needs. It is important to verify availability for specific custom sizes, but generally, the consistency of the deposit allows for flexible cutting. The stone’s structural strength permits cutting into thinner profiles for wall applications or thick blocks for landscaping.
We provide large gang-saw slabs, typically available in 2 cm and 3 cm thicknesses. These slabs maximize the visual impact of the stone, allowing for seamless countertops and large wall panels. The dimensions are generally generous, often reaching lengths of ≥250 cm, making them ideal for fabricating expansive kitchen islands or feature walls.
Standard tile formats are readily produced to suit various flooring patterns. Common sizes include 30×60 cm, 60×60 cm, and larger formats like 80×80 cm. These tiles are calibrated for precise installation. The consistency of the stone ensures that tiles from different crates will match well, creating a uniform look across the entire floor surface.
For specialized architectural needs, we offer precise cut-to-size services. This includes custom dimensions for window sills, stair treads, and risers. The stone’s hardness allows for clean, sharp edges during the cutting process. We can produce specific geometrical shapes or linear strips based on the detailed requirements of your architectural drawings.
While less common for hard granite due to the difficulty of cutting small pieces, mosaics can be fabricated for feature areas. These are typically mounted on mesh sheets for easy installation. They offer a unique way to introduce texture, detail, and slip resistance in shower floors or backsplashes using the same durable material.
For exterior landscaping, we produce thick pavers, with pedestrian areas commonly 3–4 cm and vehicular zones typically ≥5–6 cm, to withstand traffic loads. These can be supplied with flamed, bush-hammered, or sandblasted finishes to ensure safety and slip resistance. They are perfect for driveways, walkways, and patios, providing a durable and cohesive transition from indoor living areas to outdoor spaces.
To complete the flooring look, matching skirting boards and baseboards are available. These are typically cut from the same batches as the floor tiles to ensure a perfect color match. They usually feature a polished or honed top edge, providing a neat and professional transition between the floor and the wall.
For factories and large-scale processors, we supply raw blocks directly from the quarry. These blocks are carefully selected for their cubic shape and lack of internal defects. Purchasing in block form allows for maximum flexibility in custom processing and is often the preferred method for international buyers with their own cutting facilities.
Super Grey Granite is a versatile material suitable for a vast array of applications in both residential and commercial sectors. Its extreme durability makes it a top candidate for high-traffic flooring in airports, malls, and office lobbies. Additionally, its resistance to weathering allows it to be used confidently for exterior facades and outdoor landscaping. The stone bridges the gap between indoor elegance and outdoor ruggedness. It is also a popular choice for kitchen countertops and vanity tops, where hygiene and resistance to scratching are paramount. The stone’s neutral color allows it to blend with various design palettes.
The cost of this granite varies depending on several technical and logistical factors, so it is impossible to give a single fixed price. The final investment required will depend on the specific requirements of your project. Factors such as the uniformity of the stone, the size of the order, and the type of finish selected all play a role. Generally, premium-grade selections with zero visual defects command a higher value. It is best to request a detailed quote based on your bill of quantities to get an accurate understanding of the costs involved for your specific needs.
The visual quality or “grade” of the stone is a primary price driver. First-choice material, which is free from dark spots, veins, or color variations, is more expensive. Commercial grades, which may accept slight variations or minor natural imperfections, are typically offered at a more economical price point for large-scale projects.
The size of the raw block extracted from the quarry affects the price. Larger blocks that yield expansive, waste-free slabs are rarer and thus more costly. Smaller or irregular blocks are less expensive but may result in higher wastage during processing or be limited to smaller tile sizes.
The quality and type of processing applied to the stone influence the cost. Advanced finishes like leathering or high-gloss polishing require more time and abrasives than simple honed finishes. Additionally, the precision of the cutting and the application of any resin treatments to reinforce the slab add to production costs.
Different surface treatments come with different price tags. A standard polished or honed finish is usually the baseline. However, more complex texturing processes, such as flaming, bush-hammering, or sandblasting, involve additional labor and machinery steps, which can slightly increase the final cost per square meter of the material.
The volume of material used directly impacts the price. Thicker slabs, such as 3 cm or 5 cm pieces used for countertops or pavers, contain more stone and are heavier to transport than standard 2 cm tiles. This increase in raw material usage and shipping weight results in a higher overall cost.
Logistics play a significant role in the final landed cost. The distance from the quarry or factory to your project site determines shipping fees. Availability of containers and current sea freight rates also fluctuate. Working with a supplier that manages export logistics efficiently can reduce landed-cost variability.
The journey of Super Grey Granite begins in the rugged mountains where the quarries are located. Here, massive blocks are carefully extracted from the earth using advanced diamond wire cutting technologies. This method ensures that the stone is removed without causing stress fractures, preserving its natural integrity. The quarry masters select the best sections of the bedrock, looking for consistent color and structure. Once cut, these heavy blocks are inspected and marked before being loaded onto heavy-duty trucks. They are then transported from the mine site to the processing facility, ready for the next stage of transformation.
Upon arrival at the factory, the blocks undergo a precise transformation process. They are mounted onto large gang saws or multi-blade cutters that slice them into slabs of the desired thickness. Following this, the slabs move to the polishing line, where a series of abrasive heads grind the surface to a perfect finish, revealing the stone’s true color and depth. Quality control technicians monitor every step, ensuring thickness calibration is exact. Finally, the finished slabs or tiles are carefully crated and prepared for shipment, ensuring they reach the client in pristine condition, ready for installation.
Proper installation is the foundation of long-term performance for Super Grey Granite. We recommend using high-quality, latex-modified thin-set mortars compliant with international standards for heavy stones. When grouting, ensure the joint width is appropriate for the tile size to allow for minor movement. Although this granite is dense, applying a penetrating sealer upon installation is a wise preventative measure. This creates an invisible barrier against potential oil stains or grime. In busy commercial zones, resealing annually may be prudent; in lighter-use residential areas, every 18–24 months is typical.
Avoiding common maintenance pitfalls will extend the life of your stone surfaces significantly. While granite is acid-resistant, we still recommend avoiding acidic or abrasive cleaners, such as bleach or bathroom descalers, as these can degrade the sealer over time. Instead, opt for pH-neutral stone cleaners or mild soap and water for routine mopping. It is also important to sweep or vacuum floors regularly to remove grit and sand, which can act like sandpaper underfoot (though granite is highly scratch resistant, surface hazing can occur over long periods). Promptly wiping up spills, especially oils or wines, prevents them from settling into the micropores. With these simple habits, your granite will maintain its beauty for decades.
