What Are Sheet Metal Parts Assembly Services?
Sheet metal parts assembly is the process of combining fabricated components into finished products using fasteners, welding, adhesives, and hardware installation.
We cut, bend, weld, and coat your parts, then assemble them before shipment. This means one supplier, one quality standard, and one point of contact from raw material to finished product.
The result? Shorter lead times, lower total cost, and consistent quality across every component in your assembly.
Component Fabrication
Laser cutting, stamping, bending, welding—all in our facility
Surface Finishing
Powder coating, plating, or other finishes applied
Assembly & Hardware
Components joined per your specifications
Ready to Ship
Finished products, inspected and packaged

Why Integrated Assembly Matters
Most contract assemblers receive parts from multiple suppliers. We make everything under one roof—and that changes everything.
Integrated Manufacturing
- ✓ Single Source: One PO, one quality standard, one point of contact
- ✓ Better Fit: Components made together fit together perfectly
- ✓ Faster Delivery: No waiting for parts from other suppliers
- ✓ Clear Accountability: If there's an issue, we own it and fix it
- ✓ Lower Total Cost: Eliminate multi-vendor margins and logistics
Typical Contract Assemblers
- ✕ Multiple Suppliers: Coordinate vendors, manage multiple POs
- ✕ Fit Issues: Parts from different sources may not align
- ✕ Longer Lead Times: Wait for slowest supplier in the chain
- ✕ Finger-Pointing: Quality issues? "Not our parts"
- ✕ Hidden Costs: Freight, handling, and coordination overhead
"When we manufacture the components AND assemble them, we control every variable that affects your final product quality."
