Heavy Plate Fabrication

Precision & Power

Mastering the Art of Heavy Steel Plate Fabrication

Heavy plate fabrication is the cornerstone of industrial manufacturing, requiring immense power, precision engineering, and a deep understanding of material science. At Openex, we specialize in transforming thick steel plates—often exceeding 20mm (1") in thickness—into the foundational components for the world's most demanding industries.

From massive pressure vessel shells to robust structural frames for heavy machinery, our facility is built to handle the unique challenges of thick-plate work. We mitigate risks like weld distortion and material stress through controlled processes, advanced equipment, and a team of certified experts. Our integrated approach ensures that every cut, bend, and weld contributes to a final product of superior strength and dimensional accuracy.

Core Heavy Plate Fabrication Processes

1 Thick Plate Cutting

We utilize high-definition plasma and multi-torch oxy-fuel cutting systems to accurately profile carbon, stainless, and alloy steel plates up to 300mm (12") thick.

Applications of Heavy Plate Fabrication

Quality Control is Critical

Ensuring the Integrity of Heavy Plate Weldments

Thick plate welding demands rigorous inspection. We employ a suite of Non-Destructive Testing (NDT) methods, including Ultrasonic (UT) and Radiographic (RT), to verify weld penetration and integrity, ensuring your components are free from defects.
