Welded Structural Components Fabrication
High-Precision Welded Structures for Heavy Industry
Openex specializes in the fabrication of welded structural components for a wide range of sectors including construction equipment, mining, energy, marine, heavy machinery, and infrastructure. Our facilities are equipped to handle large welded assemblies with strict dimensional and strength requirements, leveraging over two decades of experience in fabricating robust structural frames, assemblies, platforms, and enclosures.
Whether it's high-load structural frames for cranes, reinforced chassis for mining trucks, or offshore platforms with extreme fatigue resistance, Openex delivers welded structures that meet both mechanical integrity and international fabrication standards.
