Gallegas 37 (Formerly SIGA 37)

One of our most popular slates from the Commercial Range, Gallegas 37 is a reasonably uniform second selection of our best-selling Gallegas 39. An affordable W1 (≤ 0,6%) T1, S1 slate, it will require sorting on site, but provides a distinctly natural look to the roof. Aesthetically and technically well suited to new build and refurbishment projects in both the residential and commercial sectors.
