SinaiGrey is the natural grey stone identity of Shalash Group — shaped around the material we quarry in Sinai, Egypt.
Since 2003, our work has followed the stone from its geological origin through extraction, selection and preparation for architectural use.
Each block is considered for its physical and mechanical characteristics, natural colour and distinctive surface. The result is a collection of stones with their own character, ready to be specified for considered spaces.
From private residences to commercial and public environments, we believe the material should speak for itself.
A closer look at the people, machinery and careful work that bring the stone out of the Sinai landscape.

The journey of the stone
From the quarry to the finished surface.
A connected journey of extraction, selection, transport and preparation — with the stone at the centre of every decision.
Our quarries
Our stone begins in the natural grey formations of Sinai, where the landscape reveals each block’s character.
Extracting blocks
Specialist cutting equipment and experienced crews work through the stone with care. Each block is selected and graded according to its natural characteristics.
Transport to our Cairo factory
Selected blocks are prepared for safe handling, loaded by experienced crews and transported to the next stage of processing in Cairo.
Manufacturing
Slabs and tiles are prepared to project requirements, with standard thicknesses of 2 cm, 3 cm and 5 cm. Slabs can reach up to 2.5 m × 1.5 m, with careful selection to maintain a considered visual match.
