Custom metal signs printed in our own shop — MAXMETAL Lite 3 mm aluminum composite: two aluminum faces bonded to a solid poly core. Flat, rigid and professional, this is the wall sign that stays outdoors for years. 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 most orders ship in 2–3 working days.
What you get
- MAXMETAL Lite 3 mm ACM panel, cut to your exact size — 12" minimum side, up to 48" × 96" (a 4 × 8 sheet)
- Printed on 3551 RA vinyl with 290 laminate — our premium print-and-laminate stack, the build we put on signs that have to look good for years
- Full-color print, edge to edge — no extra charge for photos, background colors or as many colors as you like
- Printed on one side — it mounts flat against a wall, so one side is the honest build
How long it lasts
This is the years-outdoors panel. The aluminum faces will not warp, swell or rot, and the laminate over the print takes the sun and the weather so the ink does not have to. If a coroplast yard sign is built for a season, this is built for the life of the business on the wall.
What it costs
Prices start at $75 — that is our minimum for a metal sign, and everything up to about 8.5 square feet lands on it. In plain terms: a 24" × 36" sign and a 12" × 24" sign cost the same, so if you are under the minimum anyway, order the bigger sign. Above that the designer prices your exact size by the square foot, instantly, as you drag the size sliders.
Popular sizes & prices
| Size | Price |

These are the exact prices, not estimates — and every size in between is priced instantly in the designer above.
Mounting
Two honest ways to put it up: screws straight through the panel — simple, strong, done in minutes — or standoff mounts for the finished storefront look that holds the sign just off the wall. We can drill the holes for either before it ships; just tell us hole placement in the order notes and we will take care of it.
What people use it for
Storefront wall signs, office and building identification, parking and directional signs, shop signs, menu boards — anywhere a sign hangs flat on a wall and has to look professional for a long time. Need a sign readable from both directions out on posts, like a road-side or entrance sign? Ask us about our AlumaCorr post & rail signs instead — that panel is built for exactly that job. And if the sign you have is still solid but the message changed, a printed vinyl overlay gives it a new face without buying a new panel.
Local pickup
Metal 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 lands too close to the trim. Upload art at roughly 150 DPI at final size for the sharpest result.
