Bold Color. Built for the Streets.

Some people see cars as transportation. Point A to point B. Done.

But if you're reading this, you already know that's not the whole story.

Your car isn't just what gets you around. It's what you think about at work. What you're tweaking in the garage on a Tuesday night. What you're dialing in even though nobody else will notice half the details you obsess over.

That's car culture. And it's always been about one thing: making your build unmistakably yours.

Custom paint used to be the only way. Weeks in a booth. Tape, prep, cure time, clear coat. Then you wait. And hope. And if you want to change it later? Start over.

Wraps changed all that.

Color change films let you go bold without being locked in forever. Want something aggressive now and something cleaner next year? You can do that. Want to try a color you've been thinking about but weren't sure you'd commit to permanently? Now you can.

Arlon Premium Color Change films are built around that freedom. Smooth to work with. Built for curves, edges, and real-world installs. Finishes that look as good in sunlight as they do under your shop lights.

This is for people who care how their car looks, how it feels, and how it's seen on the street.

Because bold doesn't blend in. It stands out.

Want to see what's possible? We've got the full Arlon PCC line in stock at Sacramento and Oakland.

What if your next wrap didn't look like everyone else's?

New Arlon colors dropping soon. The kind that turn heads but don't turn into install nightmares.

Bold, saturated finishes that look incredible on camera and actually lay down smooth. You're not stuck choosing between "this looks amazing" and "I can actually work with this."

This is what installers have been asking for.

When you're working on a display that has to look clean and stay flat, the material you choose makes all the difference.

That close-up edge in the photo? It's exactly what sets UltraBoard apart from standard foam core.

UltraBoard is engineered for rigidity, consistent print quality, and a smoother finish. Your POP displays, menu boards, and mounted graphics look sharp from day one — and stay that way.

Why shops keep it stocked:

- Rigid core — resists bending and bowing
- Smooth facers — clean, vibrant prints
- Sharp cuts — no tearing or flaking
- Reliable results across all applications

Tired of foam boards that warp, curl, or fight you during installs? UltraBoard fixes that.

We stock the full UltraBoard lineup in both Sacramento and Oakland. Have a project coming up? Send us a message or stop by — we'll help you pick the right board for the job.

When a sign needs to look clean up close — and actually stay flat once it's installed — UltraBoard makes a big difference.

From restaurant menus to retail displays, event signage to wall graphics — UltraBoard performs in high-traffic environments where clean edges and flat surfaces matter. The rigid core and smooth facers give you that polished, professional finish without the warping or bowing you get from cheaper foam boards.

What makes it work:

- Stays rigid after mounting — no sag, no curl
- Cuts clean for sharp edges
- Great print surface for bold, vibrant color
- Lightweight enough to handle, tough enough for daily traffic

Whether you're updating a restaurant menu wall, building out a retail display, or producing signage for an event, UltraBoard gives your work a cleaner, more consistent final look.

We stock the full UltraBoard lineup in both Sacramento and Oakland. Got a project coming up? Send us a message or stop by — we'll help you pick the right board for the job.

Foam board might seem like the simple option for quick displays — until it warps, bows, or refuses to lay flat. UltraBoard was built to solve exactly that.

UltraBoard isn’t standard foam core. It’s a full lineup of rigid substrates engineered to stay straight, print clean, and support professional-quality signage.

Here’s what each board brings to the table:

UltraBoard Classic
A dependable, rigid choice for POP displays, menu boards, and everyday retail signage.

UltraBoard White DP
Bright white facers designed for sharp, vibrant flatbed prints when color accuracy matters.

UltraBoard Mount
Lightweight and easy to handle. Ideal for mounting posters, photo prints, and presentation graphics.

UltraBoard Aluminum
A premium metal look without added weight. Great for interior displays that need long-term rigidity with a clean finish.

From retail signage to mounted client work, UltraBoard provides the structure and print quality that make your projects look intentional — not rushed.

We stock the full UltraBoard lineup in both our Sacramento and Oakland warehouses.

Painted aluminum panels might look simple, but anyone who fabricates signs knows how much the material impacts the final result. A good panel bends cleanly, takes vinyl or ink without fighting you, and still looks sharp months after it goes up.

Shops lean on painted aluminum for property signs, retail panels, regulatory work, and custom fabrication because the factory finish delivers—smooth, consistent, and built to hold color through sun, weather, and everyday wear. Whether you're dealing with valley heat, coastal fog, or high-altitude UV, these panels are made to perform.

We stock multiple colors and thicknesses at our Sacramento and Oakland warehouses, and we supply sign shops throughout Northern California, Reno, and Lake Tahoe. So whether you're running a few panels or prepping for a larger install, you can grab exactly what you need without waiting on long freight times.

If you've got a project coming up and need the right panel for the job, send us a message or stop by either warehouse — we're here to help you get it done.

When you need a clean, durable panel that’s ready for vinyl, printing, or screen work, aluminum blanks are still the material shops trust. They stay flat, print clean, and hold up outside—exactly what you want on a job that needs to last.

We stock the everyday sizes Northern California shops run constantly (12×18, 18×24, 24×24, 24×36) in .040, .063, and .080. No guessing, no weird cuts—just the core blanks fabricators actually use.

Perfect for parking signs, property signage, regulatory panels, and custom printed work, each sheet gives you a smooth, consistent surface that behaves the way it should.

And because we stock locally in Sacramento, you’re not stuck waiting on freight or delays. If you need blanks today, they’re on the rack.

If you’ve got a project coming up and need the right size or gauge, send us a message or drop by the warehouse — we’ll get you what you need.
