GRA2003 GREY SPI ALPALHÃO GRANITE

Gra2003 bought a quarry of the well known SPI Alpalhão, in the Alentejo region (Portugal).

Under the ground of the city with the same name Alpalhão granite is also known as SPI granite a fine/medium grained stone. The quarries in the Alpalhão region are made of fine or medium-grained granite with an elongated shape.

We consider this grey granite the number one grey granite because it has the most uniform colour/ pattern, high resistance but due to its fine/medium grain is great to transform.

SPI is also one of the favourite granite of world class architects, as you may see here.

«Gra2003 Grey SPI Alpalhão» is from now on the official name of every stone extracted from our Alpalhão quarry.

Other names: Alpalhão Blue – Nomenclature EN 12440, Alpalhão Blue Gray, SPI, MFI, Alpalhão Grey.
