Grey Basalt combines a fine, uniform charcoal-grey grain with compressive strength of 250–350 MPa, notably higher than most of our granite tread options. This density makes it especially well suited to high-traffic staircases that need to perform for decades without visible wear.
Grey Basalt treads are typically finished all-sides flamed and brushed, combining slip resistance on the walking surface with a refined, finished edge. Polished, honed, and bush-hammered finishes are also available for entryways, patios, or interior applications with different needs.
Grey Basalt is highly frost-resistant, with water absorption of just 0.1–0.3%, making it a dependable choice for exterior staircases and garden steps in cold climates. It's sourced from Vietnam, China, and Mongolia, all regions known for producing dense, weather-resilient basalt.
Yes. Grey Basalt's charcoal-grey tone and exceptional strength suit both a contemporary residential staircase and a heavy-traffic commercial or public entryway. Its uniform fine grain gives a clean, modern look that pairs well with a wide range of architectural styles.
Grey Basalt offers higher compressive strength than most granites at a typically lower price point, though Soho Granite has even lower water absorption and a wider finish range, including leather and brushed. Grey Basalt is often the better value choice for a dark, durable tread.
