Advanced Manufacturing for Structural Steel
Heavy-Duty Steel Fabrication Engineered for Strength, Safety & Scale
Flue gas cooling and waste heat recovery
Capturing waste energy to lower the cost of carbon capture
LJUNGSTRÖM’s Advanced Manufacturing division delivers precision-engineered structural steel components built to perform under heavy loads, harsh environments, and rigorous construction timelines. With some of the largest fabrication, machining, and coating capabilities in the U.S., we produce the steel that critical infrastructure depends on.
High-Consequence Performance Requirements
Structural components must withstand:
- Extreme and repeated loading
- Vibration, fatigue, uplift, and wind forces
- Thermal expansion and environmental exposure
- Tight tolerances for erection and fit-up
Any misalignment, weld inconsistency, or dimensional error becomes a costly delay or a safety hazard.
Compressed Project Schedules
General contractors and EPCs face relentless timeline pressures:
- Fast-track delivery schedules
- Supply chain bottlenecks
- Long lead times from traditional fabricators
- Coordination across trades and phases
Missed steel delivery means missed milestones—and costly penalties.
Increasing Structural Complexity
Today’s facilities—data centers, distribution hubs, manufacturing plants, and energy systems—require:
- Larger and heavier members
- More complex assemblies
- Multi-process steel components
- Strict QA/QC and traceability
- Integrated machining and coating
Most fabricators simply cannot handle this scale. LJUNGSTRÖM can.
Reliable, heavy-duty steel built to engineered specifications
High-volume repeatability for multi-site or multi-story builds
Superior coatings for long-term corrosion and environmental resistance
Precision machining for bolt patterns, interfaces, and connection points
Documentation, traceability, and certification
Predictable timelines from a vertically integrated partner
This is exactly what LJUNGSTRÖM delivers.
