Granite — Glossary entry
Category: Glossary entry
Extremely hard natural stone for interior and exterior stairs.
Granite is one of the hardest natural stones and thus ideal for heavily used stair treads. It is extremely abrasion-resistant, frost-proof and easy to maintain. Granite is suitable for both representative interior stairs and outdoor stairs, as it permanently withstands weathering. The surface can be polished, flamed or blasted — flamed and blasted variants offer higher slip resistance.
