Selco Manufacturing is an AISC-certified structural and miscellaneous steel fabricator serving civil and infrastructure contractors across the country. Our team supports complex public works projects that demand precision, documentation, and strict adherence to regulatory standards.
Selco delivers steel fabrication solutions built to perform in high-load, high-visibility environments, ranging from bridge fabrication, highway structures, and transit platforms to stairs, canopies, and safety railings
Steel Fabrication Services
At Selco, we provide comprehensive steel fabrication services tailored specifically to infrastructure and public works applications. Our capabilities extend beyond standard fabrication to include complex assemblies, heavy structural components, and miscellaneous steel required for transportation and public projects.
We work closely with civil contractors, engineers, and public agencies to ensure that every structural steel component meets project specifications and performance requirements. Whether we are fabricating large bridge elements or detailed safety structures, our team prioritizes accuracy, traceability, and on-time delivery with every project.
In addition, we help contractors reduce field modifications while maintaining compliance with agency requirements by keeping a tight control over fabrication processes and documentation.
Our fabrication services support:
- Bridge and overpass construction
- Highway and transportation infrastructure
- Transit stations and rail facilities
- Municipal and public works projects
- Industrial and utility structures
Infrastructure-Focused Steel Fabrication Capabilities
Custom Fabrication
Every infrastructure project presents unique design constraints. Selco provides custom steel fabrication built around project-specific drawings and engineering requirements. We fabricate to exact specifications, supporting both primary structural members and miscellaneous steel components.
Our team collaborates during the detailing phase to identify potential fabrication efficiencies and constructability improvements. Addressing these details early helps to minimize delays during installation and inspection.
Bridges, Overpasses, and Highway Structures
Bridge and overpass projects are among the most demanding applications for steel fabrication. Components need the ability to withstand dynamic loads, environmental exposure, and long service lifespans.
We understand the importance of dimensional accuracy and proper fit-up in these applications. That’s why our fabrication processes emphasize precision to ensure seamless field installation and reduced rework.
Selco fabricates structural steel for:
- Overpass framing systems
- Highway support structures
- Bridge rehabilitation
- Bridge Railing
- Historic Bridge Replacement
Platforms, Walkways, Stairways, and Catwalks
Transit stations, industrial facilities, and public infrastructure often require elevated access structures. You can count on Selco to fabricate steel platforms, walkways, stairways, and catwalks that prioritize durability and safety.
These components must meet structural load requirements while complying with safety codes and accessibility standards. Our fabrication team ensures that each assembly aligns with project drawings and regulatory guidelines, delivering dependable structures that support daily public use. We also dry-fit components before installation to confirm proper fit-up and ease of field assembly.
Railings, Guardrails, and Safety Structures
Safety structures are critical in public infrastructure environments. From pedestrian railings on overpasses to guardrails along transit platforms, these elements protect the public and must meet strict design standards.
Our steel fabrication processes ensure consistent weld quality, proper material selection, and adherence to project-specific safety codes for projects like:
- Pedestrian and traffic railings
- Guardrails and protective barriers
- Handrails and safety enclosures
Materials and Fabrication Expertise
Material selection directly impacts performance, longevity, and compliance in infrastructure projects. Selco works with a range of metals to meet the structural and environmental requirements of each application.
Carbon Steel, Stainless Steel, Aluminum, Copper Alloys
Carbon steel remains a primary material in steel fabrication due to its strength and cost efficiency. For projects requiring corrosion resistance or reduced weight, we also fabricate using stainless steel and aluminum. In specialized applications, copper alloys may be incorporated to meet specific design or performance objectives.
We align material choice with project demands to help contractors achieve both performance and cost objectives. Our material expertise allows us to recommend appropriate solutions based on:
- Load-bearing requirements
- Environmental exposure conditions
- Agency specifications
- Budget considerations
- Lifecycle performance expectations
In-House Detailing and Engineering Support
Steel fabrication for infrastructure projects requires detailed coordination. Selco provides in-house detailing and engineering support to ensure fabrication drawings accurately reflect project intent.
In-house detailing streamlines communication and reduces the risk of discrepancies between design and fabrication. This integrated approach helps maintain schedule integrity and supports smoother inspections.
Our detailing capabilities include:
- Shop drawing development
- Coordination with engineering teams
- Material tracking and documentation
- Compliance with project submittal requirements
Certifications and Quality Standards
Quality and compliance are central to public infrastructure work. Selco maintains rigorous quality systems to meet industry and agency expectations.
AISC Certification and Compliance
Selco is an AISC certified simple bridge & building fabricator, demonstrating our adherence to nationally recognized quality management and fabrication standards. AISC certification reflects a commitment to documented procedures, qualified personnel, and consistent inspection protocols.
AISC certification supports compliance with many public agency requirements and reduces audit and inspection risk.
For civil contractors and public agencies, this certification provides confidence that:
- Fabrication processes meet established industry benchmarks.
- Weld procedures and personnel are qualified to the most stringent standards
- Material traceability and documentation are maintained.
- Quality control measures are consistently applied.
Infrastructure Project Experience
Selco has extensive experience supporting infrastructure projects that demand coordination, accountability, and technical expertise. We understand the layered approval processes and documentation requirements associated with public works contracts.
