Stone Quarry

Triângulo de Pedra stands out from the Portuguese stonework market, mainly because it is equipped with a diamond wire saw mechanism that allows quarrying frontal cuts, either in vertical, horizontal or diagonal sections.

This extracting process is mostly done with no use of explosives, which minimizes the negative effects caused by quarry waste.

This also allows a high percentage of stone exploitation, both on quarry section cuts, as well as on raw stonework blocks.

The diamond wire saw extracting mechanism combines perfectly, two of our main concerns: innovation and environmental sustainability.


Our company’s main goal is to take competitiveness to a whole new level.

Our team of experienced and dynamic professionals, allows us to respond quickly and efficiently to all our customers’ demands.

Besides the transformation of raw material coming from our own stone quarries, we are also experienced in processing any type of ornamental stones.
