Import Black Galaxy Granite Tile — Buy in Bulk from Supplier in India

Black galaxy granite tile from C K Sons Granera is a homogeneous, compact, holocrystalline rock quarried in India. Its composition includes orthopyroxene (bronzite) at 20% by volume, with grain sizes from under 1 mm to 2 mm, clinopyroxene at 40%, and labradorite at 30%. Accessory minerals, magnetite, olivine, biotite, and hornblende, make up the remaining 10%. The stone registers a hardness of 6 on the Mohs scale and a specific gravity of 3. This medium to coarse grained hypoabyssal rock features porphyroblasts of orthopyroxene, giving it a distinctive dark colouration and the classification of bronzite-dolerite.

The mineral structure of this granite tile directly affects its performance in commercial and residential installations. The scattered orthopyroxene crystals create the characteristic metallic fleck pattern that defines black galaxy granite in the global market. Labradorite content contributes to subtle blue-grey iridescence under certain lighting conditions. With a hardness of 6, the material resists scratching from common household and light industrial abrasives. The specific gravity of 3 indicates moderate density, relevant for load calculations in vertical cladding applications. Standard industry practice for black galaxy granite includes water absorption testing and flexural strength measurement, though the listing does not state values for either property. Typical slab dimensions for export-grade material range from 600 mm x 600 mm to 1200 mm x 2400 mm, with thicknesses of 20 mm or 30 mm being standard for tiles.

Buyers of this material include interior design firms, monument and memorial manufacturers, premium residential developers, and precision instrument manufacturers seeking surface plates. The stated applications, interior decorations, wall linings, tombstone memorials, and instrument surface plates, reflect the stone's dimensional stability and aesthetic uniformity. Importers should confirm with C K Sons Granera the exact tile dimensions, thickness tolerances, and surface finishes available (polished, honed, or flamed). Packaging for ocean freight typically involves wooden crates with foam separation, but this should be verified directly. The supplier's tier is marked as imported, with a harbor trust classification, indicating they handle export documentation for international shipment.

C K Sons Granera operates from #16/33, First Floor, Wuthucattan Street, Periamet, Chennai 600003, Tamil Nadu, India. The company's tier classification is imported, indicating they source material from domestic Indian quarries for re-export or direct international trade. Their trust tier is harbor, which in marketplace terminology suggests a verified business registration without full supplier verification. The response rate shows 0.00% with zero average response hours, meaning no response data is available from recent buyer inquiries. This absence of response metrics should factor into communication planning for prospective buyers.

The listing provides no information about company history, annual turnover, number of employees, production capacity, or specific quarry relationships. What is known is limited to the Chennai office address and the product-specific geological description they publish. Buyers should independently verify C K Sons Granera's quarry access or trading relationships, their ability to provide consistent material batches, and their experience with export packaging and documentation. The company does not claim any certifications on this listing, nor do they state MOQ, lead times, or incoterms. Direct negotiation will be necessary to establish these commercial terms.
