Massive Load-Bearing Structural Fabrication
Large-scale industrial facilities, offshore platforms, and heavy mining machinery require robust, highly engineered structural frameworks. These massive structures must support extreme static and dynamic loads, requiring absolute perfection in deep-penetration welding and geometric alignment.
With 180 acres of factory space and overhead lifting capacities up to 250 tons, Openex is built for heavy structural fabrication. We specialize in the turnkey manufacturing of oversized structural steel frames, heavy equipment chassis, and complex modular grid structures that simply will not fit in standard fabrication shops.
Structural Frame Specifications & Limits
We build to your exact structural CAD models, complying strictly with global welding codes. Below are our facility parameters for massive frames:
| Maximum Envelope Size | Virtually unlimited. Fully assembled modules up to 30m x 8m x 6m inside the shop. |
|---|---|
| Maximum Weight | Up to 250 Tons (Overhead Crane Limits) |
| Welding Codes | AWS D1.1 (Structural Steel), ASME Section IX, EN 15085. |
| Metrology & Metrology | Large-volume Laser Trackers (Leica/Faro) for extreme dimensional accuracy over long spans. |
| Materials Handled | Carbon Steel (A36, Q345, S355), HSLA Steels, Heavy I-Beams, H-Beams, and Tubular profiles. |
Our Work: Structural Frameworks
The Manufacturing & QC Process
Using CNC plasma, laser, and heavy sawing centers, we process massive I-beams, H-beams, structural tubing, and heavy gusset plates to exact lengths and bevel angles.
Our certified welders execute multi-pass Submerged Arc Welding (SAW) and Flux-Cored Arc Welding (FCAW) to ensure maximum joint strength across the entire load-bearing frame.
Structural failures are not an option. We utilize Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) to inspect critical welds, followed by Laser Tracker inspection to verify overall frame geometry.
To protect against extreme weather or corrosive industrial environments, completed frames are moved into our massive steel grit blasting booths, followed by multi-coat epoxy or polyurethane painting.
