Mining & Construction

Severe-Duty Fabrication

Built to Survive Extreme Environments

Equipment used in mining, quarrying, and heavy construction is subjected to continuous high-impact loading, severe abrasion, and structural fatigue. At Openex, we possess the massive lifting capacity (up to 250 tons), heavy CNC machining centers, and wear-resistant steel processing expertise required to build the toughest components on earth.
