Fine Black Granite Slab, 20mm Polished Finish, Countertop Grade

Fine Black Granite

The Fine Black Granite Slab provides a dense, low-porosity surface designed for high-traffic installations in commercial and residential environments. This igneous rock features a consistent fine-grained mineral structure that ensures structural integrity during fabrication and long-term use. It meets the rigorous demands of kitchen surfacing and exterior cladding due to its high compressive strength and resistance to environmental stressors.

Built for the Job

This material is a staple for contractors and stone masons requiring a uniform aesthetic without the large veining patterns found in other natural stones. The tight grain structure makes it less susceptible to chipping during edge profiling or sink cut-outs. Site supervisors select this specific stone for its predictable performance under heavy loads and its ability to withstand high temperatures in culinary applications.

• Fabrication of heavy-duty kitchen countertops and island tops.

• Installation of high-traffic floor tiles in lobbies and hallways.

• Exterior wall cladding and threshold plates for commercial builds.

Product Highlights

Surface Durability

The material achieves a high Mohs hardness rating, ensuring it resists scratching from steel utensils and heavy foot traffic.

Thermal Resistance

• Withstands direct contact with heated cookware without structural cracking.
• Maintains dimensional stability across varying temperature gradients.

Technical Specifications

What’s Included

• 1 x Fine Black Granite Slab (Dimensions vary by stock lot)

On-Site & Workshop Notes

• Always verify slab dimensions and dye lot consistency before starting multi-slab installations.

• Use diamond-tipped wet saws for cutting to prevent overheating the stone matrix and edge micro-cracking.

• Apply a high-quality penetrating sealer post-installation to enhance the moisture barrier on the polished surface.

• Ensure sub-structures or cabinetry can support a dead load of approximately 54kg per square meter.
