Facts / Chronicle

The corporate history allows discovering the roots of STAG.

Since its foundation, STAG has developed into a highly specialised company in the bulk material technology sector. Today, the four business areas (projects, products, service, rail wagon) shape the business activity of STAG (Schüttgut Technik AG).

Created as a transport company specialised in the bulk transportation of bulk products, we have always been an expert in the handling of bulk material ( in powder and granular form).

In addition to its core business “System engineering projects”, STAG has become a broadly-based and globally operating company in the area of bulk material technology.

Corporate histories are always shaped by people, and both the founders and the employees have made history. Without their commitment, capabilities, loyalty and motivation, the continuity and development of the company would not have been possible.

Foundation: 1954
