Bayan Signage cuts, folds, welds and powder-coats aluminium 3D letters in its own Ajman factory, from shopfront names to building letters 2.5 m tall. We pretreat before coating, isolate every fixing from the aluminium and install on frames our own team welds, and outdoor letters carry a 5-year warranty on LEDs, powder coat and structure.
Aluminium 3D letters are sign letters made from aluminium sheet folded into hollow boxes, or cut from solid plate, then powder-coated in the brand colour. Aluminium weighs roughly a third of steel and does not rust, so a letter over a metre tall can still be carried by two people and fixed to cladding with modest structure. They are the workhorse for showrooms, warehouses, retail parks, schools, factory names along Emirates Road and rooftop letters across the UAE.
On day one, every powder-coated letter looks the same. The difference appears in the third summer, when cheap powder chalks and fades, poorly pretreated faces peel, and stainless bolts tightened straight onto aluminium leave white corrosion blistering under the paint. Because we route, fold, weld and powder-coat in our own factory at Alam Square, Industrial Area 2, Ajman, we control the pretreatment, the powder grade and the isolation of every fixing.
Bayan Signage is the production arm of Bayan Advertising, which has worked in the UAE market for 15 years, and our Ajman factory has fabricated aluminium signage since 2016. Large facade and rooftop letters also need steel frames, and those are welded in the same building. Our project manager coordinates the letters, the frame, the authority drawings and the lift on installation day, so you deal with one contact throughout.

Most large lit or coloured letters in the UAE have an aluminium body. These are the builds we recommend, depending on size, lighting and exposure.
Hollow powder-coated letters from 300 mm to well over 2 m. Light enough for sandwich panel cladding and ideal for daytime sites such as warehouses.

Designers size letters for the road they face. Draftsmen produce shop drawings with return depths, bracing, fixing points and, for large signs, the steel frame used in the permit submission.
Faces and backs are CNC-routed to ±0.1 mm. Returns are folded to the outline and welded, and letters above about 800 mm get internal ribs so faces stay flat in the heat.
Each letter is degreased and pretreated, then powder-coated to your RAL colour inside and out, so condensation on humid nights cannot oxidise bare internal aluminium.
Lit letters get LED modules, weep holes and a full-brightness test. Every letter is checked against the approved artwork for size, colour and coating thickness before dispatch.
Our crew sets the rail or galvanised frame first, levels it, then hangs and bolts each letter with isolated stainless fixings and seals every penetration in the facade.
This is the specification we start from for an outdoor fabricated letter on a sunny UAE facade. We adjust it to height, wind exposure and lighting, and itemise every change.
| Component | Our standard | Upgrade options | Why it matters |
|---|---|---|---|
| Sheet | 1.5 to 3 mm aluminium, marine-grade for coastal sites | Thicker faces on very large letters | Thicker faces stay flat and resist drumming when the sun heats one side. |
| Pretreatment | Degrease and conversion treatment before coating | Primer coat for coastal sites | The invisible layer that decides whether paint peels after two summers. |
| Coating | Polyester powder coat to RAL, inside and out | Architectural-grade, metallic or textured powder | Higher-grade powders resist chalking and fading far longer on south and west walls. |
| Bracing | Internal ribs above about 800 mm | Full internal frame on rooftop letters | Keeps faces flat and takes fixing loads in shamal winds. |
| Fixings | Stainless studs with nylon isolation washers | Rail system or galvanised steel frame | Isolation stops galvanic corrosion where stainless meets aluminium in humid air. |
| Drainage | Weep holes at the lowest point | Vented returns on lit letters | Lets condensation escape, protecting LEDs and stopping stains on the wall. |
Aluminium is forgiving to fabricate and unforgiving to under-specify. These are the points we raise on almost every facade job.
Standard and architectural-grade powders look identical when new. On a west-facing facade, the cheaper grade can chalk and fade within two or three summers, and strong reds and yellows go first. Repainting letters at height means scaffolding or a boom lift, which costs far more than the difference in powder. On sunny elevations we quote the higher grade by default and show the saving if you prefer otherwise.
We start from about 25 mm of letter height for every 3 m of viewing distance, then add margin for drivers who glance for a second or two. A warehouse name read from 100 m along an industrial road usually needs letters of around 800 mm to 1 m. Return depth follows height: 50 to 80 mm up to 600 mm, about 100 mm at a metre, and 120 to 150 mm above that.
A two-metre letter behaves like a sail in a shamal. Letters on rooftops, corners and high facades need engineered frames and anchors fixed back to the building structure, not to the cladding skin. A sign held by light brackets can look fine for months and then fail in one storm. We design the frame with the letters and include it in the authority drawings where required.
Stainless bolts tightened directly onto aluminium in humid coastal air cause galvanic corrosion: white powder around the fixing that creeps under the paint as blisters. Nylon washers and sleeves cost almost nothing and prevent it. We fit them on every outdoor letter, and it is worth asking any supplier whether their quote includes them.
A RAL or Pantone reference looks different on screen, on paper and on powder-coated metal in UAE daylight, and gloss level changes it again. We spray a small aluminium sample in the chosen powder and gloss for you to hold against the facade. It adds a day or two, and it is the only reliable way to approve a brand colour that will be on the building for a decade.
Every set is priced from its drawing. Send the logo, the facade size and a photo, and you will receive an itemised quote covering letters, frame, installation and permits, usually within 24 hours.
Fabrication time follows the total length of return to fold and weld. A long name in script letters has far more perimeter than a short block logo.
Standard polyester powder is the baseline. Architectural grades, metallic and textured finishes, and multi-colour letters add cost and curing time.
Front-lit or halo-lit letters add acrylic faces or back panels, LED modules, drivers, wiring and deeper returns to house them.
Rooftop and high facade letters may need a galvanised steel frame and engineered fixings, which can cost as much as the letters themselves.
Boom lifts, cranes, scaffolding and night work on tall buildings can be a large share of the installation price.
Large outdoor signs normally need authority approval, often with structural drawings. Our draftsmen prepare them, and the work is quoted as its own line.
Facade and rooftop letters usually need approval before installation. In Dubai that is normally Dubai Municipality, with RTA involvement for some signs facing major roads, or the free-zone authority such as JAFZA, DMCC or TECOM inside their areas. Sharjah and Ajman municipalities handle their own emirates, and Abu Dhabi free zones set their own rules.
Large or rooftop signs may also need structural drawings for the frame and the building owner's written consent. Our technical draftsmen prepare the elevation, structural plan and Arabic and English wording for the submission. Requirements vary by location and change over time, so we confirm the current rules for your exact plot at the survey.
CNC routing, welding and powder coating happen in our Ajman factory, so pretreatment and powder grade are never left to someone else.
Galvanised steel frames for large and rooftop letters are welded in our factory and designed together with the letters.
Outdoor aluminium letters are covered for 5 years on LEDs, powder coat and structure, documented at handover.
Our draftsmen prepare shop drawings, structural plans and submissions for municipalities, RTA and free zones, and follow each one through.
Our crews install across the UAE with boom lifts and high-access safety procedures, and the crew that fabricates installs.
Letters, frame, lighting, installation and permits are listed separately, so you can compare like for like.
Cost depends on letter size and perimeter, powder grade, lighting, the frame and access. A set of 400 mm unlit letters on a ground-floor fascia is a modest job; two-metre lit letters on a tower roof involve a frame, a crane or lift and structural drawings. Send the logo, the sizes and a photo for an itemised quote, usually within 24 hours.
It depends on the finish you want. Aluminium is lighter and better for large, painted or coloured letters, especially on cladding and rooftops. Stainless steel is better when you want a bare metal finish such as brushed or mirror. Many signs combine both: an aluminium body with isolated stainless fixings.
All paint fades eventually, but the rate varies widely. Architectural-grade polyester powder over proper pretreatment holds colour for many years on sunny UAE facades, while standard powder can chalk within two or three summers. Strong reds and yellows are the most sensitive, so they deserve the best grade available.
We fabricate letters up to 2,500 mm high as standard, and larger names are built in sections and joined on site. Letters above about 800 mm get internal bracing, and rooftop letters sit on a galvanised steel frame designed for the wind load at that height.
Yes. Powder coat is available across the RAL range and many special colours. We spray an aluminium sample for approval, because colours on metal in daylight look different from the screen or paper, and we confirm matt, satin or gloss at the same time, since gloss level changes how a colour reads.
Yes, and their low weight is a big reason they are chosen. We fix through to the supporting structure or onto a rail system rather than relying on the thin skin of the panel, and seal every penetration against water. We check what sits behind the cladding at the survey.
Usually yes. Rooftop and large facade signs typically need municipality or free-zone approval and the building owner's consent, and some authorities ask for structural calculations for the frame. We prepare the drawings and confirm the requirement before fabrication, so the frame does not need redesigning later.
Wash with water and mild detergent once or twice a year, more often on dusty industrial roads, and avoid solvents and abrasive pads that strip gloss. Check high-level fixings after major storms and keep weep holes on lit letters clear. Touch up any chip in the coating promptly, especially near the coast.
