S.I.G.MA. S.r.l. was founded in the year 1990 in Locate Varesino by people who had more than thirty years of experience in refractory manufacturing with the aim to become a specialist in the glass market.
In 2014 S.I.G.MA. S.r.l. became S.I.G.MA. GROUP with the construction of a new plant in Plovdiv, Bulgaria, becoming the largest European manufacturer of special shapes for glass furnaces.
To meet the growing demand of our refractories the production capacity was doubled, bringing it up to 500 tons per month.
S.I.G.MA. GROUP is able to provide the glass industry with a truly comprehensive range of refractory thanks to the cooperation with reliable partners, each specializing in its own field.
