Custom H Beam Fabrication
Precision-Welded H Beams for Heavy Industrial Applications
Openex specializes in the fabrication of custom welded H beams tailored for high-strength, corrosion-resistant, and load-bearing applications across industries such as construction, bridges, shipbuilding, petrochemicals, offshore structures, and energy infrastructure. Our advanced production line, supported by proprietary welding fixtures and technology, ensures minimal distortion and superior alignment during the beam assembly process.
To overcome the typical welding deformation challenges faced in traditional H beam production, Openex developed a specialized H beam welding fixture system. This innovative solution uses synchronized rotating turntables with limit racks and clamping elements to hold web and flange plates firmly in position, allowing for controlled and distortion-free welding. This technology significantly improves both structural integrity and fabrication efficiency.
