CNC Routed Traffic Signs for Precision and Durability
Built for roadway compliance and long-term performance, our CNC routed traffic signs deliver exact sizing, clean cutouts, and reflective finishes, ideal for DOT, municipal, and custom applications.
CNC Routed Traffic Signs
At Diamond Metal Finishing, our CNC routed traffic sign fabrication combines accuracy, compliance, and outdoor durability. Using high-speed CNC routers, we cut aluminum substrates into precise DOT-specified shapes, radii, and borders—ensuring every sign meets visibility, safety, and installation requirements.
From regulatory stop signs to custom wayfinding panels, our CNC routing process guarantees consistent dimensions, smooth edges, and repeatable results. Backed by ISO 9001:2015 certification, DOT/MUTCD compliance, and 3M MCS™ Warranty, our CNC fabricated signs are engineered to withstand long-term outdoor exposure and heavy-duty use.
Why Choose Diamond Metal Finishing For CNC Routed Signs?
- DOT & MUTCD-Compliant Shapes and Sizes: All signs are routed to Department of Transportation and MUTCD standards for regulatory accuracy.
- CNC Routing for Precision Cutouts and Shapes: We use high-speed CNC routers to create clean, accurate shapes, corners, and sign borders—ensuring exact sizing every time.
- Reflective Sheeting Integration: CNC-routed panels are finished with Diamond Grade, High-Intensity, or Engineer-Grade reflective films for maximum visibility.
- Chem Film Treatment for Durability: Every aluminum panel receives chromate conversion coating (chem film) to improve corrosion resistance and adhesion of reflective sheeting.
- UV-Stable Printing for Legends & Graphics: Legends, arrows, and graphics are applied using UV-cured digital printing for clarity and fade resistance.
- Mounting & Installation Ready: Pre-drilled holes and hardware options ensure every routed sign arrives installation-ready.
- 3M Certified Production: Manufactured under the 3M Matched Component System (MCS™) Warranty, ensuring outdoor performance and resistance to UV degradation, peeling, and fading.

Frequently Asked Questions
What is CNC routing in traffic sign manufacturing?
CNC routing uses precision-controlled cutting machines to create clean, exact sign shapes, borders, and holes per DOT specifications.
What materials are used for CNC routed signs?
We primarily use .080″ and .125″ aluminum panels, treated with chem film before applying reflective sheeting.
Are CNC routed signs DOT-compliant?
Yes. All routed signs meet MUTCD and DOT standards for dimensions, reflectivity, and materials.
Can you make custom shapes beyond standard regulatory signs?
Yes. CNC routing supports custom cutouts, arrows, shields, and unique formats.
Do you pre-drill mounting holes?
Yes. All CNC routed signs come with DOT-standard or custom hole patterns.
How long do CNC routed signs last outdoors?
With 3M reflective sheeting and overlaminate, routed signs are UV, weather, and graffiti resistant, lasting 7–12 years depending on material grade.
Can you handle bulk orders?
Yes. We can produce both small runs and large-volume DOT projects with consistent quality.
What is the lead time for CNC routed traffic signs?
Standard lead time is 3–5 business days, depending on order size and complexity.
