Import Black Rustic Slate Stone — Buy in Bulk from Supplier in India

Black Rustic Slate Stone from Associated Natural Stones India features a dark base with light grey veining and rust-colored iron oxide deposits, creating a distinctive natural pattern. The product is offered as tiles, slabs, and custom-cut paving, with thicknesses of 1 cm, 2 cm, and 3 cm. The finish options include natural both faces, one face calibrated, and one face honed, allowing flexibility for architectural applications. The material is sourced from layered quarries in India and split by hand to preserve natural fracture lines.

This slate has a bulk specific gravity of 2.65 and a dry modulus of rupture of 11 N/mm², indicating high structural integrity. Its compressive strength of 117 N/mm² dry and 100 N/mm² wet confirms suitability for heavy-use interiors and exteriors. The water absorption rate is 0.15%, well below the 0.5% threshold for frost-resistant stone. Unlike machine-sawn alternatives, this product is chisel-split, preserving its natural texture and reducing surface uniformity.

Architects specify this slate for kitchen countertops, entranceways, and conservatory flooring where a durable, organic aesthetic is desired. Buyers in Europe and North America often select it for high-end residential projects. The product is sold in cut-to-size formats, with delivery estimated at 2 to 3 weeks. Trade terms are not specified, but packaging is typically in wooden crates with foam padding between slabs. Custom sizes are available, though minimum order quantities are not stated.

The supplier’s trust tier is harbor, suggesting basic verification through shipping or export documentation. No response rate or average response time is recorded, and no details are provided about workforce, production capacity, or years in business. The company appears to focus on cutting and exporting slate rather than quarrying or processing raw stone.

Custom cutting is offered, but minimum order quantities and lead times are not specified, requiring direct inquiry.
