What do Zorra Granite treads look like?
Zorra Granite is a deep, uniform dark grey granite with a fine-to-medium grain structure that gives it a clean, sophisticated appearance. It's a popular choice for staircases that need a classic, timeless black surface.
What finish options are available for Zorra Granite treads?
Zorra Granite is commonly finished with flamed, waterjet, and brushed treatments for slip-resistant stair applications, with polished, honed, and bush-hammered options also available depending on the setting. Flamed remains the standard recommendation for exterior stair treads specifically.
How durable is Zorra Granite for high-traffic staircases?
Zorra Granite has a compressive strength of 200–230 MPa and low water absorption of 0.2–0.4%, giving it strong durability and frost resistance for high-traffic staircases in both residential and commercial settings. It holds up reliably across seasons and heavy foot traffic.
Is Zorra Granite suitable for exterior staircases?
Yes. Zorra Granite is frost-resistant and weather-resilient, making it well suited to exterior staircases, entryways, patios, and garden steps in addition to interior applications. Its dense, uniform surface performs consistently across a wide range of weather conditions.
How does Zorra Granite compare to Alston Granite?
Both are grey granites with similar strength and density ranges, but Zorra Granite is typically finished with a waterjet-and-brushed combination for a distinctive texture, while Alston Granite is more commonly flamed. The choice often comes down to preferred surface texture rather than performance.
