HSS Group was founded as a family business by trade professionals experienced in international trade and in the mining and marble industry. What started as a small marble production and trading company has grown into a multifaceted group with a global reach.
While shipping marble from our quarries in Bilecik to many markets, led by India and China, we expanded into marine supplies and ship spare parts, construction and software.
Today each business line works with its own specialist team. As a group we share one goal: to deliver efficient, reliable and lasting solutions for our partners.
