DRILLSTAR INDUSTRIES

DRILLSTAR Industries was founded in 1986, from the determination and know-how of a team specialized in designing and producing oil & gas drilling and fishing equipment. Among our employees, many managers and manufacturing or servicing operators have more than 20 years experience in this field of activity, and speak the same language as the customers do wherever oil and gas are being drilled for. Since the early days of the company, DRILLSTAR Industries has successfully applied its core competence to other fields of activity which require comparable levels of quality, reactivity, and competitiveness, such as the aerospace, rail, medical, textile, and paper industries. Moreover, the company now offers a broader range of services, that includes integration capabilities, testing and turnkey supply of complete sets or subsets of industrial equipment.
