Aluminum Flat Cut-Out Letters — The Architectural Choice for Lobbies, Facades & Monuments
Solid aluminum plate, precision CNC cut, finished in brushed metal, painted, anodized, or powder-coated. Non-illuminated, no electrical, no permit in most jurisdictions — just clean, permanent, architectural-grade letters that last 20+ years in any climate.
What Are Aluminum FCO Letters?
"FCO" stands for flat cut-out — solid aluminum plate, CNC-routed or waterjet-cut to the exact shape of each letter, then finished and mounted to a wall. No electrical, no illumination, no permit hassle. Just dense, dimensional, permanent signage.
Anatomy of an aluminum FCO letter
No wiring, no diffusion, no power supply — just solid metal, a precision edge, a finish, and a clean mounting system. The simplicity is what makes it last.
-
1
Aluminum plate face
5052 or 6061 architectural-grade aluminum plate, 1/8" to 1" thick. Dense, rigid, and dimensionally stable in any climate.
-
2
Laser-cut edge
CNC waterjet or fiber-laser profiled to the exact letter outline. Edges are deburred and broken so the profile reads crisp from any angle.
-
3
Painted finish
Mathews Paint, powder coat, brushed, clear anodize, or mirror-polish — specified to your brand palette or architect's drawings.
-
4
Standoff hardware
Tapped blind-hole on the back of each letter accepts threaded studs or stainless standoff pins for flush, pad, or floated mounting.
What Aluminum FCO Letters Cost in LA
Case-by-case — we quote firm after a site visit or artwork review.
Pricing is case-by-case. Every Aluminum FCO letter project is custom — letter count, height, thickness, finish (matte/brushed/polished), mounting method — all affect cost. We provide a firm quote after a site visit or artwork review.
Permits are a fixed $1,500 — our flat fee for permit runners, drawings, and city coordination. City fees (plan check, inspection, use permits) are billed at cost with zero markup and paid directly by the client. See Sign Permits for the full policy.
Standard lead time is 2–3 weeks for production after permit approval. Complex fabrication may add time; we tell you upfront.
Three Ways to Mount Aluminum Letters
FCO letters give you three distinct visual effects on the wall. We pick the right one by walking the site and checking wall type, interior access, and architectural intent.
Standoff Pins
Stainless steel pins hold each letter 1/2"–2" off the wall, creating a crisp drop-shadow and a pronounced architectural depth. The default for lobbies, HQ signs, and premium commercial facades.
Flush / Pad Mount
Each letter sits tight to the wall, adhered with VHB tape or set onto hidden foam pads. Minimal shadow, reads as part of the wall plane. Fastest install and the approach for brick, stone, and delicate finishes.
Pin-Mount (Painted Hardware)
Threaded studs tapped into blind holes on the back, with hardware color-matched to the letter finish. Zero visible fasteners, zero shadow gap — used where the architect specifies a "letters sit on the wall" aesthetic.
Concept to Installed Letters in 4 Steps
No permits mean no waiting on city plan-check. FCO letters skip that step entirely, compressing the whole project to 3–5 weeks door-to-door.
Design
Site measurements, elevation photos, font and letter-height selection, layout mockup on your actual facade or lobby wall.
Material Selection
Plate thickness, aluminum grade, finish sample (brushed, anodized, paint chip, or polished) — signed off before anything goes on the router.
CNC / Laser Fabrication
Waterjet or fiber-laser cut, edges deburred, back-tapped for hardware, finish applied, QA photo set delivered before ship.
Install
Licensed crew arrives with a full-size paper pattern, levels the layout, drills, sets standoffs or adhesive, installs letters in one visit.
Six Reasons Architects Specify Aluminum
Architectural Grade
The sign language of banks, museums, hospitals, and Class A towers. Reads as part of the building envelope, not an applied sign.
No Electricity Required
Zero wiring, zero power supplies, zero ongoing utility cost. Install anywhere there's a wall — no conduit needed.
No Permit in Most Cases
Non-illuminated exterior letters are exempt from sign permit requirements in most LA-area jurisdictions — saving weeks of plan-check.
Indoor / Outdoor
Aluminum doesn't corrode, warp, yellow, or fade. The same letter works on an exterior facade in Gardena or an interior lobby in Century City.
Timeless Aesthetic
Brushed aluminum, bronze anodize, and polished stainless don't go out of style. Install today, look current in 20 years.
Specify-to-Spec
Any thickness, any finish, any font, any mounting spec. AIA/SE drawing-grade shop production — no surprises, no substitutions.
Where Aluminum FCO Letters Belong
Corporate Lobbies
Brushed or anodized letters on the reception wall — the visual handshake before anyone even shakes your hand.
Law Firm Reception Walls
Bronze anodize or painted-satin letters signal confidence and permanence. The unofficial default for partners' name walls.
Hotel Monuments
Stand-alone monument signs with large dimensional metal letters — weather-proof for decades, always on-brand.
Building Address Numerals
The street number above the entrance — large, legible, structurally permanent. Specified by architects, loved by fire inspectors.
Architects' & Design Offices
Firms that spec FCO letters for clients use them on their own entrances — a quiet professional signal.
Clinic & Medical Interiors
Anodized, non-reflective finishes that read cleanly under clinical lighting — and hold up to daily disinfectant wipe-down.
When Aluminum FCO Is — and Isn't — Your Best Choice
Aluminum is the premium FCO material. Here's an honest look at when to spec it and when another letter type will serve you better.
Choose aluminum FCO if Yes
- You need permanent architectural letters with no electrical needs.
- Your business is corporate, legal, medical, institutional, or architectural.
- You want a letter that reads as part of the building, not an applied sign.
- The install is exterior & needs to last 20+ years in SoCal weather.
- Budget between $2K and $15K and a 3–5 week timeline.
Consider another option if Maybe not
- You're budget-constrained or interior-only — see acrylic/PVC FCO letters.
- You need the sign to glow day and night — see front lit channel letters.
- You want an illuminated premium metal look — see reverse channel letters.
- You need the lowest possible price with no dimension — see vinyl graphics.
- You're on a freestanding lot and need a big identity — see monument signs.

Frequently Asked Questions
What is the difference between flat-cut and fabricated aluminum letters?
Flat-cut aluminum letters (FCO) are cut from solid aluminum plate using a CNC waterjet or router. They have a consistent thickness throughout and are non-illuminated. Fabricated aluminum letters are three-dimensional letters built from aluminum sheet bent into channel shapes with welded returns, creating a hollow enclosure that can house internal LED illumination. Flat-cut aluminum is used when a solid metal appearance without illumination is desired; fabricated aluminum is used when internal lighting is required.
How thick are aluminum FCO letters?
Standard aluminum FCO letters are cut from plate stock ranging from 1/8 inch (3mm) to 1 inch (25mm) thick. The most common thicknesses for commercial signage are 1/4 inch and 3/8 inch, which provide substantial dimensional depth visible from street level while remaining practical for mounting. Thicker plate stock (1/2 inch to 1 inch) is used for large letters where additional depth and visual weight are desired, or for freestanding letters that need structural rigidity.
What finishes are available for aluminum letters?
Aluminum letters can be finished in several ways. Brushed aluminum provides a natural metal look with directional grain lines. Clear anodized aluminum preserves the natural silver color with a protective oxide layer. Bronze and dark anodized finishes provide rich, warm tones. Painted finishes using the Mathews Paint system allow any custom color, including PMS and Pantone matches. Powder coating provides a thick, durable finish ideal for high-traffic exterior locations. Mirror-polished aluminum delivers a highly reflective chrome-like appearance.
How do aluminum letters compare in cost to acrylic or PVC letters?
Aluminum FCO letters typically cost 2 to 3 times more than equivalent PVC letters and 1.5 to 2 times more than acrylic letters due to the higher material cost and the specialized cutting equipment (waterjet) required to process aluminum plate. However, aluminum letters offer superior durability, weather resistance, and a premium metal appearance that plastic materials cannot replicate. For exterior applications expected to last 20+ years, aluminum often provides better long-term value despite the higher initial investment.
