Industrial mechanical metalworking

SOHRA group of companies was founded in Belarus. Today we run business in different European Union countries such as Lithuania, Romania, as well as in Eurasian Economic Union and CIS countries. The main line of our business is exports of Belarusian products (trucks, busses, tractors, loaders, mining dump trucks, agricultural and high-tech machinery, tires, ventilation systems, etc.).
