The existing company was born in Milan-Italy in 1928, on the ruins of an old factory, which manufactured some rubber items and products.
The charters members, who were technicians specialized in the execution of industry rubber articles, belonged to the family that is still present in the society.
In '50s and '60s, the company knew a great expansion period, during which it developed its own technologies to manufacture special tubes, industry wheels and other rubber items.
The first modern unit, where the new industrial production started, was built in 1968 and it specialized its production on textile and steel carcass rubber conveyor and elevator belts.
SIG was among the first Italian industries to develop a foreign market, at first all around Europe, and then also in Americas, Africa, Asia and Australia.
During the '80s and '90s the continuous touch with foreign countries allows SIG to improve its range of production with considerable investments in new technologically advanced manufacturing lines.
In the new millennium, SIG SpA, UNI EN ISO 9001/2000 certified, is the only Italian producer and one of the most qualified world manufacturer in the field of textile and steel rubber conveyor belts for elevators and heavy applications, snowmobile tracks and other technical rubber items.
