From custom stainless steel enclosures to architectural features and food processing equipment, our fabrication capabilities ensure the highest quality standards and finishes for stainless steel products.


Aluminum Fabrication

Our aluminum fabrication services cater to projects that demand lightweight, durable, and corrosion-resistant components. Using advanced aluminum welding and forming techniques, we produce custom aluminum structures, panels, and enclosures for aerospace, automotive, marine, and architectural applications.



Structural Steel Fabrication

Sigma Source is a leading provider of structural steel fabrication services for construction projects of all sizes and complexities. Our expertise in structural steel design, fabrication, and erection ensures the successful delivery of high-quality steel structures, including buildings, bridges, industrial facilities, and infrastructure projects.



Sheet Metal Fabrication

We offer comprehensive sheet metal fabrication services for producing custom metal components and assemblies. With state-of-the-art equipment and skilled craftsmen, we fabricate sheet metal parts with precision, efficiency, and consistency, meeting the exact specifications and requirements of our clients.


Rigging Fabrication

Our rigging fabrication services encompass the design and manufacture of custom rigging equipment and components for lifting, hoisting, and securing heavy loads. From wire rope slings to lifting beams and spreader bars, we provide reliable rigging solutions that ensure safety, efficiency, and compliance with industry standards.


High Strength Steel

Sigma Source specializes in working with high-strength steel alloys to produce components and structures that require exceptional strength-to-weight ratios and durability. Our expertise in high-strength steel fabrication enables us to deliver innovative solutions for demanding applications in aerospace, automotive, construction, and other industries.



Mild Steel

Our alloy steel fabrication services cater to projects that demand enhanced mechanical properties, corrosion resistance, and heat resistance. Whether it’s alloy steel pipe fittings, valves, or structural components, we have the expertise and resources to fabricate custom alloy steel products to meet the most stringent requirements and specifications.



Alloy Steel

Acoustic hangers offer an effective solution to impede airborne noise transmission from the space below and prevent noise or vibration from the floor above infiltrating the room below. Sigma Source, a renowned elastomer, serves as a valuable component, providing additional isolation that can significantly enhance the acoustic isolation of the room.


Cold Roll

Sigma Source provides cold roll forming services for producing complex metal profiles and shapes with high precision and efficiency. Our cold roll forming process ensures uniform material properties and dimensional accuracy, making it ideal for applications that require tight tolerances and consistent quality.


Pickled & Oiled

We offer pickled and oiled steel fabrication services for projects that require clean, corrosion-resistant surfaces and improved formability. Our pickling and oiling process removes mill scale and impurities from the surface of hot-rolled steel, enhancing its weldability and paint adhesion while providing superior corrosion protection for long-lasting performance.




Custom Strut Channels

We provide custom-designed strut channels for supporting and securing piping, conduits, and other mechanical systems in commercial and industrial applications. Our strut channels are available in various sizes, materials, and configurations to accommodate the unique requirements of each project, offering versatility, durability, and ease of installation.
