Custom structural steel fabrication, heavy equipment setting, and specialized rigging. Built for Complexity. Engineered for Precision.
Precision Fabrication. Complex Solutions.
Where aerospace standards meet industrial scale.
Our Experience
When fabrications are unusual, complex, and often one-of-a-kind, experience matters. Our team brings structural capability together with mechanical expertise to produce high-performance fabrications with actuating or mechanized features that most contractors simply cannot execute. Over time, our success in aerospace expanded into industrial, manufacturing, and mission-critical facilities where owners need fabrication they can trust.
The Foundation
Our Fabrication Group was established more than 20 years ago as a specialized operation that began in the aerospace industry, where tolerances are tighter, quality standards are higher, and complexity is expected. That foundation shaped everything about how we build.
The Sauer Group Differentiators.
Our millwright teams support equipment setting, precision alignment, heavy mechanical assembly, and specialized installations that demand coordination, technical skill, and an uncompromising commitment to safety.
Precision That Starts in the Shop
Aerospace origins mean exacting standards. Tight tolerances, meticulous planning, and QA/QC built into every step of the process.
Complex. Custom. One of a Kind.
We routinely tackle fabrications that are unusual in nature: structural systems with actuating or mechanized features, heavy assemblies requiring specialized rigging, and structural solutions that require both mechanical and structural expertise.
Fabricate It. Install It. Own the Result.
Our union crews fabricate and erect, giving you a single source accountable for fit, function, and schedule from shop floor to final installation.
Fabrication & Millwright Services
From structural steel and custom assemblies to equipment setting and specialized rigging, we deliver.
Structural Steel Fabrication & Erection
We fabricate and erect structural steel systems from equipment support structures and mezzanines to complex custom frames,with full shop-to-field accountability.
Steel & Aluminum Fabrication
Custom steel and aluminum fabrications to project-specific tolerances, including assemblies with actuating or mechanized features that require the intersection of structural and mechanical expertise.
Millwright Services — Equipment Setting & Alignment
Precision installation of heavy industrial equipment: setting, grouting, leveling, and laser alignment for pumps, compressors, turbines, conveyors, and production line machinery.
Specialized Rigging & Heavy Lifting
Safe and engineered rigging plans for moving, positioning, and setting heavy machinery and oversized fabrications. Our crews are trained in rigging operations where precision and safety are non-negotiable.
Corrosion Control
Corrosion control services for structures and shipping vessels, protecting critical assets for long-term performance in demanding environments.
Load Testing & Performance Verification
Load testing of fabrications and functional testing of mechanized and operable assemblies, ensuring every complex fabrication performs as designed before it reaches final installation.
What Millwright Work Really Demands.
Millwright work is not general labor, it is precision mechanical craft. When a production line goes down, when a critical piece of equipment needs to be set, aligned, and commissioned correctly the first time, the contractor you call matters. Sauer Group's millwright teams bring the technical rigor, safety discipline, and union craft experience that mission-critical equipment setting demands.
Equipment Setting
Heavy industrial equipment set to manufacturer specifications: anchored, grouted, shimmed, and leveled for reliable long-term operation.
Precision Alignment
Laser alignment of rotating equipment such as pumps, motors, compressors, and turbines, reducing wear, vibration, and unexpected downtime.
Heavy Mechanical Assembly
Assembly of large, complex mechanical systems in the field, including coordination with structural, piping, and electrical trades for integrated installations.
Specialized Installations
Complex one-of-a-kind installations requiring both structural and mechanical expertise, including fabrications with actuating, rotating, or mechanized features.
What We Fabricate
Structural Steel Systems
Engineered Structural Fabrication
Custom structural steel frames, equipment pads, mezzanines, pipe racks, and support structures fabricated to project drawings and erected by our union field crews. We work from 3D AutoCAD and SDS2 models, ensuring structural integrity and dimensional accuracy from shop to site.
Capabilities include:
- Structural steel frames and support structures
- Equipment support platforms and mezzanines
- Pipe racks and structural pipe supports
- 3D AutoCAD and SDS2 modeling and drafting
- Shop-to-field erection by union crews
What We Fabricate
Aluminum Fabrication
Lightweight. Strong. Precision-Built.
Aluminum fabrication for applications requiring high strength-to-weight ratios, corrosion resistance, or specialized structural requirements. We apply the same exacting standards to aluminum as we do to structural steel: precise fit, proper surface treatment, and documented quality control.
Capabilities include:
- Custom aluminum structural fabrications
- Specialty assemblies requiring lightweight structural solutions
- Fabrications with actuating or mechanized features
- Corrosion-resistant designs for demanding environments
What We Fabricate
Complex & Custom Fabrications
One-of-a-Kind. Built to Perform.
Many of our most demanding projects involve fabrications that are unusual, complex, and singular in nature, such as assemblies with moving parts, mechanized features, or structural-mechanical combinations that require capabilities most contractors don't have. Our aerospace heritage means we are built for this work.
Capabilities include:
- Fabrications with actuating or mechanized features
- Structural systems combining mechanical and structural design
- Complex custom assemblies to tight tolerances
- Load-tested and performance-verified fabrications
Built Right. Tested Right.
Every fabrication that leaves our shop is documented and verified. We don't ship until it passes.
Load Testing
Fabrications are load tested to verify structural performance before installation. No assumptions, no shortcuts.
Mechanized Performance Testing
Operable and mechanized assemblies are functionally tested to confirm all actuating features perform as designed.
Corrosion Protection
Surface treatment and corrosion control applied to specification, extending the service life of structures in demanding environments
Documentation & Traceability
Full documentation package provided for every fabrication: material certifications, weld records, testing results, and dimensional verification.
Complex Fabrication Across Critical Industries.
Our millwright and fabrication capabilities serve the industries that demand the most, where precision, safety, and reliability are non-negotiable.
Industrial & Manufacturing
Equipment setting, precision alignment, and structural fabrication for production facilities, process lines, and plant utilities. We minimize downtime and keep production schedules on track.
Data Centers
Structural support systems, equipment skids, and precision millwright services for mission-critical facilities where installation accuracy directly affects system reliability and uptime.
Healthcare & Life Sciences
Specialized structural fabrications, equipment setting, and custom assemblies for healthcare facilities and pharmaceutical environments where compliance and quality are paramount.
Higher Education & Institutional
Custom structural and mechanical fabrications for campus facilities, including occupied-space installations requiring coordination, safety, and minimal disruption.
Why Work With Sauer Group.
Aerospace-Grade Precision, Industrial Scale
Our Fabrication Group was built on aerospace standards, one of the most demanding environments for quality, tolerances, and documentation. That discipline shapes every project we take on, regardless of industry.
One Team. Shop to Site.
We self-perform both fabrication and installation. Our union crews know what they built, how it was designed to fit, and how to set it correctly. That continuity eliminates coordination gaps and protects your schedule.
Fifth-Generation Experience
Since 1876, Sauer has taken on the work other contractors won't. Complex, custom, one-of-a-kind fabrications are not new to us. They are where we have always excelled.
