Performance electronics enclosures
Our capabilities scale from prototype development through production—delivering consistent quality whether building one specialty component or 500 units.
WHY AUTOMOTIVE AFTERMARKET BUILDERS CHOOSE METALFAB GROUP
Automotive aftermarket fabrication demands performance quality, precision dimensional accuracy, appearance standards, and the ability to scale from prototype to production volumes. Our capabilities address these critical requirements.
Zero-Defect Quality Heritage
Our Stainless Works performance exhaust background established zero-defect manufacturing discipline across all automotive applications. This heritage means more than quality certification—it means systematic processes preventing defects before they occur.
​
Approach to quality:
-
First-article inspection validates production setup with dimensional verification
-
Final inspection confirms 100% compliance with engineering specifications
-
Documented procedures ensure consistency across production runs
-
Quality documentation available for traceability and customer requirements
This discipline extends to every automotive application we fabricate—structural brackets, exhaust components, and custom performance assemblies. It's foundational to our process.
Integrated Tube & Sheet Metal Fabrication — Our Core Differentiator
Most fabrication shops specialize in either sheet metal or tubular work. We excel at both— we integrate them seamlessly for exhaust systems, brackets, and performance components.
​
Our 4 core capabilities working together:
-
BLM Laser Tube Cutting: Precision laser cutting of tubing profiles with complex geometries, exact wall thickness transitions, and custom mounting provisions.
-
Tube Bending: Production-grade tube bending up to 2" diameter with tight bend radius control and wall thickness consistency. Creates precise structural bends and components that integrate perfectly with sheet metal flanges and mounting brackets.
-
TIG Welding: Precision TIG welding for smooth, aesthetic joints in exhaust manifolds, downpipes, and performance assemblies. Stainless steel (304/316) welding ensures corrosion resistance and appearance performance customers demand.
-
Sheet Metal Laser Cutting: Precision laser cutting of flanges, mounting brackets, and sensor provisions that integrate seamlessly with tubular assemblies. Mounting holes and features bolt directly—no field adjustment required.
Most aftermarket builders coordinate between separate tube and sheet metal shops. We do it all under one roof—one quality system, one point of contact, no delays.
Precision Fabrication for Performance & Appearance
Performance and aftermarket components demand tight dimensional tolerances and professional
appearance. Every detail matters—from exhaust flow to bracket positioning to weld quality.
​
Precision capabilities:
-
Exhaust System Precision: BLM laser tube cutting for manifold collectors with exact internal geometry, TIG welding for smooth thermal-cycling joints, and laser-cut sheet metal flanges that mount perfectly.
-
Structural Integration: Precision tube bending for suspension and frame components combined with laser-cut sheet metal gussets. Components integrate seamlessly without field modification.
-
Dimensional Accuracy: Precision laser cutting for tubing and sheet metal. Tight bend radius control. Every mounting hole and flange positions components exactly as designed.
-
Appearance Quality: TIG welding produces smooth joints without polishing.
Precision fabrication means components work right the first time—manifolds flow smoothly, brackets integrate without adjustment, and appearance meets professional performance standards.
Quality Documentation & Traceability
Performance and aftermarket customers require quality documentation, material traceability, and assurance that components meet specifications consistently. ​
​
Our documentation capabilities:
-
First Article Inspection reports with dimensional verification and material traceability
-
Material certifications and mill test reports for all components
-
In-process inspection records documenting production consistency
-
Final inspection documentation confirming specification compliance
-
Production documentation archived for future reference and change control
-
Specific inspection criteria and documentation per customer requirements
​
Material Selection for Automotive Applications
Performance and aftermarket applications demand materials suited to specific environments—thermal cycling in exhaust systems, corrosion exposure in underbody components, and appearance for aesthetics.
​
Material options:
-
Carbon Steel: Structural brackets, suspension components, and cost-effective powder-coated applications. 22 ga to 10 ga gauges depending on load requirements.
-
Stainless Steel (304/316): Exhaust system components requiring thermal and corrosion resistance. Maintains appearance without coating for performance-critical aftermarket applications.
-
Aluminum (5052/6061): Weight-reduction for performance efficiency. Non-magnetic for sensor integration. Natural corrosion resistance with excellent surface finishing.
-
Galvanized Steel: Cost-effective corrosion protection for underbody and structural components in washdown or salt-air environments.
​
