Aluminium Sign Letter Ref 303
Cut from plate 6 mm or thicker, so the edge you see is solid metal.
Reference 303 as photographed in our Shenzhen workshop before packing.
Product Overview
What Ref 303 Actually Is
Reference 303 is a custom sign letter set built to the artwork supplied, with the construction chosen to suit the letter height and the fixing surface, made in aluminium with a lacquered aluminium face. It is not a stock item. The photograph shows one set we built; what you receive is the same construction cut to your own letters, your own height and your own colour.
Aluminium weighs far less than stainless at the same size, so very tall letters stay within what a facade fixing — and a scaffold crew — can carry.
Letters are computer-cut for precision, fully welded, and painted to the PMS or RAL reference you supply.

Key Benefits
Why Buyers Specify This Build
Four things reference 303 gives you that a generic letter order does not.
One finish across the set
Face and returns are finished together after welding, so the grain runs the same way on every character.
Installs without a specialist crew
A 1:1 template, pre-welded studs and a flat-packed kit mean a general fitter can set the job out and hang it the same day.
Lit or unlit from the same drawing
If lighting is added later, the return depth and cable entries are already sized for it.
Built to survive the location
Grade 316 stainless for coastal and high-salt exposure, 304 inland, lacquer over aluminium where colour matters more than metal.
The same construction installed on site — depth, finish and fixing carried over unchanged.
Application Scenarios
Where This Reference Belongs
Brand rollouts, franchise programmes, corporate identity refreshes and multi-site fit-outs.
Who it is for. Sign contractors and fit-out companies buying letter sets to install themselves, brand owners rolling an identity across several sites, and architects specifying lettering as part of a facade package.
The problem it solves. A logo that has been redrawn by the sign shop rather than cut from the brand file is the detail a brand manager always spots.
- Wayfinding and Building Identification — Numbers, unit marks and directional lettering that stay readable for the life of the building.
Manufacturing Process
How Ref 303 Is Made
The same four stages run on every set, which is what makes a repeat order match the first one.
We stage
We work from your vector artwork, not from a redraw
Colours stage
Colours are matched to the RAL or Pantone reference you quote
Mixed-Material stage
Mixed-material marks are built as one assembly so the seams line up
The stage
The logo and the lettering ship together on one template
LED modules and power supplies used in our illuminated letters are CE, RoHS and UL approved.

Materials and Quality Control
Material and Finish Notes
Aluminium is lacquered rather than left bare, so the colour is whatever RAL or Pantone reference you quote.
Welds are ground back before the finish is applied, so the grain or polish runs across the joint rather than stopping at it. Faces are checked against the approval drawing for letter spacing and stroke weight before packing.
Letters are checked against the approval drawing before they are wrapped.
Certifications
LED modules and power supplies used in our illuminated letters are CE, RoHS and UL approved. Certification of the metalwork itself is TBC — ask for current documentation with your quotation.
Comparison
How This Compares With the Alternatives

| Fabricated box letter | Closed deeper shell | Anywhere LED modules have to live inside the letter |
| Flat-cut letter | Single plate, cut through | Reachable positions, numbers and plaques |
| Printed or vinyl lettering | Applied film | Short-term promotion, not permanent identification |

Guides That Cover This Build
Answers
Questions About Ref 303
The points buyers usually raise before ordering a sign letter set.
What is the minimum order quantity?
TBC — the source material for this catalogue does not state a minimum order quantity. Send your artwork and we will confirm it with the quotation.
Can these letters be illuminated?
Yes. Direct illumination lights the face and indirect illumination puts the light behind the letter as a halo. Tell us which before fabrication, because it changes the return depth.
How is the set packed for export?
Letters are individually wrapped and packed flat. Mirror-polished faces keep their protective film until the moment of installation.
What is the smallest letter you can make?
Letter height starts at 40 mm. Below that the return depth and the fixing studs stop being practical.
Are the LED components certified?
The LED modules and power supplies we use in illuminated letters are CE, RoHS and UL approved.
What stainless grade do you use?
Stainless steel 304 or 316, chosen on request. 304 suits ordinary inland exposure; 316 is the better choice near the coast or anywhere with a high salt or chemical load.
