The journey of Ailsa Craig granite begins with quarrying. Massive blocks of rock are extracted using heavy machinery, such as hydraulic drills, wire saws, and explosives. Once removed, the blocks are roughed out, then transported to the company's processing plant on the mainland.

After initial processing, the granite is further cut and shaped according to the client's specifications. This includes precision cutting for paving slabs, louvers, and bespoke architecture pieces. The final product is then quality-checked, packaged, and dispatched to destinations across the globe.
