Integrated Solutions from Workshop to Mine Site
OJ Mining Projects and Services is an integrated fabrication, engineering and logistics partner. We design and fabricate structural and process-critical steelwork, weld and install HDPE piping, and keep plants running with planned and shutdown maintenance.
Because fabrication, transport and installation are handled by one team, each stage is planned around the next — reducing hand-offs, cutting downtime and keeping projects on schedule.
