Custom AlumaCorr signs, printed and built in our own shop — 10 mm corrugated aluminum composite panel: solid aluminum faces over a fluted core. Rigid, flat and seriously weatherproof, this is the sign you put up and leave up for years, not a season. Design yours above in any size from 12" up to a full 48" × 96" sheet — the price is quoted instantly in the designer as you pick your size, and orders ship in 2–3 working days.
What you get
- AlumaCorr 10 mm panel cut to your size — anything from 12" on a side up to 48" × 96" (a full 4×8 sheet)
- Printed on 3551 RA vinyl with 290 laminate — our premium print-and-laminate stack, built for years in the sun and rain
- Printed one side or both sides
- Full color, edge to edge — photos, logos and background colors at no extra charge
One side or both
This is the rigid sign we print double-sided. A road sign read from both directions, a development board at a subdivision entrance, a sign hanging where traffic passes both ways — pick "both sides" in the designer and it prices the second side on the spot, honestly, as its own line.
Post & rail kit
Want it standing at the road like a real estate or construction site sign? Add the optional post & rail kit — steel posts and rails your sign hangs from. The kit comes in two sizes, for 4×4 and 4×8 signs, same price either way; the designer adds it to your quote when you tick it.
Sizes and pricing
Prices start at $75 — that is our minimum for this panel, and small signs land on it. From there the price follows the size: pick your dimensions in the designer and the quote updates instantly. Need bigger than 4×8? A 5×10 oversize panel exists, but it is seamed and mounted differently, so call us on the number at the bottom of the page and we will quote it properly.

Where these signs go
Subdivision entrances, construction sites, farm gates, business road signs, real estate development boards — anywhere a sign has to stay flat, stay put and still look right a few winters on. If you only need a season — a campaign, a listing, an event — a coroplast yard sign does that job for a lot less money. And if the sign is going on a wall, single-sided, our MaxMetal wall sign is lighter and cheaper than AlumaCorr; ask us which one fits. Already have a panel that's still solid but says the wrong thing? A printed vinyl overlay re-faces it for a fraction of a new sign.
Local pickup
Rigid panels are free local pickup at our Johnsonville shop — they don't survive parcel carriers, so we don't ship them. Checkout offers pickup and we'll email you the moment your sign is ready, usually 2–3 working days.
Artwork
Use the designer above to lay out your sign — type, shapes, and your own photo or logo. It shows the panel edge and a safe area, so nothing important crowds the trim. Upload art at roughly 150 DPI at final size for the sharpest result.
