Natural Slates

Slate is a fine grained metamorphic stone that may be split into thin slabs or slates. It is waterproof, fireproof, resistant to weather extremes, and requires little or no maintenance.

The range comes from Tegral ThrutonePlus, LBS and SSQ, all offering Haldane Fisher customers a wide selection of beautiful, yet durable natural slates.
