Metal Signage
Metal signage is what you specify when the sign has to look permanent. Stainless steel lettering, brushed logos, engraved plaques and formed metal facade letters for corporate entrances, institutional buildings and premium retail. It costs more than acrylic and it lasts considerably longer, which for an entrance sign is usually the right trade. We cut, form and finish it in our own workshop.
What is metal signage?
Metal signage covers any sign fabricated from sheet or formed metal rather than plastic. In practice that means stainless steel, brass, aluminium and powder coated mild steel, cut into letterforms and logos, engraved into plaques, or fabricated into built-up letters with faces and returns. It can be mounted flush, raised on standoffs, or illuminated from behind for a halo effect.
What you are buying is permanence and material honesty. A brushed stainless letter reads as solid metal because it is solid metal, and that registers differently from a metallic-effect vinyl on acrylic, particularly close up where visitors actually stand. It also handles Singapore humidity, rain and cleaning without degrading, so an entrance sign specified properly in 316 stainless will outlast several generations of the fit-out around it.

Why specify metal
Where metal signage works
Wherever permanence, prestige or close viewing matters.
Choosing the grade: 304, 316 and why it matters here
Stainless steel is not one material. The two grades used in signage are 304 and 316, and the difference is corrosion resistance. 304 is the general purpose grade and is perfectly adequate for interior signage in a conditioned lobby. 316 contains molybdenum, which substantially improves resistance to chlorides, and that is what matters in humid, coastal and marine air.
Singapore is humid year round and much of the island is close enough to the sea for airborne chlorides to be a real factor. For any exterior metal signage, or interior signage in an unconditioned or open lobby, 316 is the sensible specification. Using 304 outdoors is a common way to save money at quoting stage and produces tea staining, the light brown surface discolouration that appears on under-specified stainless within a year or two.
Tea staining is a surface effect rather than structural failure, and it can be cleaned, but it recurs, and on a prestige entrance sign that is precisely the impression you were paying to avoid. We specify 316 for exterior work as standard and will tell you when 304 genuinely is enough.
Finishes, and how they behave in practice
Brushed or satin is the default for good reason. The directional grain hides fingerprints and light scratching, holds an even appearance across large letters, and photographs well. It is what most corporate reception signage uses and it ages gracefully.
Mirror polish is dramatic and difficult. It reflects everything around it, shows every fingerprint and every fine scratch, and needs frequent cleaning to look intentional rather than neglected. It works in controlled, high-maintenance environments such as hotel lobbies and works badly anywhere people touch it or cleaning is infrequent. We will use it, but we will flag the maintenance reality first.
Powder coating gives you any colour on a metal substrate, combining metal durability with brand colour accuracy. The caveat is that the coating is the protection, so a deep chip on an exterior sign exposes the steel beneath and becomes a rust point. Brass develops a natural patina over time, which some clients want and others do not, and it can be lacquered to slow that down if you prefer it bright.
Cut, formed or engraved: three ways to make a metal sign
Flat cut lettering is laser or waterjet cut from a single sheet, typically 3mm to 10mm thick, and mounted on standoffs. It is the most common and most affordable metal build, and the standoffs create a shadow line that gives the letters depth without the cost of fabricating returns.
Built-up or fabricated letters have a face and welded returns, producing real depth of 20mm or more with a hollow interior. That interior is what allows halo lighting, so if you want illuminated metal lettering this is the build. It costs significantly more because each letter is individually formed, welded and finished.
Engraved plaques are cut or etched into a solid plate, with the recessed detail usually infilled in a contrasting colour. This is the traditional approach for commemorative and statutory signage, and it is the most durable of the three because the information is cut into the material rather than applied to it. If you want illuminated metal, our backlit signage page covers the halo lighting side in detail.
What we settle before quoting
Metal is the most specification-sensitive material we work with, so these matter.
- Material and grade: 316 stainless for exterior and humid positions, 304 for conditioned interiors, brass or aluminium where appropriate
- Build: flat cut on standoffs, built-up fabricated letters, or engraved plate
- Thickness, typically 3mm to 10mm flat, more for large freestanding letters
- Finish: brushed or satin, mirror polish, powder coated colour, or patinated brass
- Illumination: unlit, or halo lit using the hollow interior of built-up letters
- Mounting: standoff pins, flush concealed fixings, or a hidden rail for long runs
If the budget will not stretch to solid metal, acrylic signage with a brushed metal finish gets close to the look for considerably less. For exterior facade work see building signage.
What metal signage costs in Singapore
Metal is the most expensive material in the range, driven by material cost, the labour in cutting and finishing, and welding on built-up work. It is also the longest lived, so the cost per year in service compares better than the headline figure suggests.
| Plaques and small flat-cut signs | from around S$400 | Engraved plaques, door plates, small logos and single-piece flat cut lettering. |
| Reception and entrance lettering | around S$1,200 to S$3,000 | Flat cut or built-up stainless lettering for reception walls and main entrances. |
| Large or illuminated metal work | S$2,500 to S$5,000 and above | Large facade lettering, halo lit built-up metal letters, and full multi-element metal signage sets. |
Indicative ranges rather than quotes. Grade, thickness, finish and whether letters are flat cut or fabricated move the figure substantially. Site visits are free and carry no obligation.
How we work
Metal is less forgiving than plastics, so the setting out stage does more work.
Why Creative Sign for metal
Most metal signage disappointments trace back to grade rather than workmanship. A 304 stainless sign in an exterior or open-lobby position looks perfect for a year and then develops tea staining, and by then the saving has long since stopped feeling clever.
We specify 316 for exterior and humid positions as standard and tell you plainly when the cheaper grade is genuinely sufficient. We also install from a full-size template, because on brushed metal at eye level, letters a couple of millimetres out of alignment are immediately visible.

Licensing, insurance and warranty
Metal signage is frequently installed in entrances and lobbies where the surrounding finishes are expensive, so we carry public liability insurance for all on-site work. Where metal lettering is halo lit and needs connecting to mains supply, that connection is made by our own BCA-Licensed Electrical Worker.
Fabrication is warranted for 12 months and installation for 6 months, written on your quote. Metal is the material least likely to generate a warranty claim, since correctly specified stainless does not fade, yellow or degrade. Where claims do arise they tend to concern finish consistency or fixing, both of which the warranty covers.
- Public liability insurance for all on-site installation
- BCA-LEW licensed for halo lit and illuminated metal work
- 12 months warranty on fabrication
- 6 months warranty on installation
- Correct grade specified so corrosion is designed out, not warranted around
Frequently asked questions
How much does metal signage cost in Singapore?
Engraved plaques and small flat-cut pieces start around S$400. Reception and entrance lettering in stainless typically runs S$1,200 to S$3,000. Large or halo lit metal work goes from S$2,500 upward. Material grade, thickness, finish and whether letters are flat cut or fabricated are the main cost drivers.
What is the difference between 304 and 316 stainless steel?
316 contains molybdenum, which greatly improves resistance to chlorides found in humid and coastal air. 304 is fine for interior signage in a conditioned space. For exterior work or open lobbies in Singapore, 316 is the correct specification. Using 304 outdoors commonly leads to tea staining, a light brown surface discolouration, within a year or two.
Which finish should I choose?
Brushed or satin for most applications. The directional grain hides fingerprints and light scratches and ages well, which is why it dominates corporate signage. Mirror polish looks dramatic but shows every mark and needs frequent cleaning. Powder coating gives exact brand colour on a metal substrate, with the caveat that a deep chip outdoors becomes a rust point.
Can metal signage be illuminated?
Yes, most commonly as halo or backlit lettering. Built-up metal letters are hollow, so LEDs can sit inside facing the wall to throw a glow around a solid metal silhouette. This is a popular combination for corporate entrances because it keeps the premium material and adds evening presence. Front lighting is not possible, since metal is opaque.
Is metal signage worth the extra over acrylic?
It depends on the position. For an entrance that visitors stand a metre from while waiting, yes, because real brushed metal and a metallic vinyl finish are obviously different at that distance. For a sign viewed from ten metres or a position with a tight budget, acrylic with a brushed finish gets you most of the appearance for considerably less.
How do I maintain metal signage?
Very little is needed. Wipe brushed stainless with a soft damp cloth, following the grain direction, and dry it. Avoid abrasive pads and chlorine-based cleaners, which damage the passive layer that makes stainless corrosion resistant. Mirror finishes need more frequent attention. Lacquered brass should not be polished, since that removes the lacquer.
How long does metal signage last?
Correctly specified stainless steel signage routinely outlasts the fit-out around it, often decades rather than years. There is no face to fade and no plastic to yellow. On illuminated builds the LEDs and driver will need attention long before the metal does, which is why we position drivers where they can be reached.
Can you make metal signage that matches our brand colour?
Yes, through powder coating, which applies a durable colour finish to the metal substrate and gives accurate brand matching while keeping metal durability and weight. Alternatively, brushed stainless can be combined with a coloured element, such as a powder coated logo mark alongside brushed lettering, which is a common way to keep both the material quality and the brand colour.
What warranty and insurance do you provide?
Every sign we make carries 12 months warranty on fabrication and 6 months on installation, and those terms are stated in writing on your quote rather than left implied. We also carry public liability insurance for all on-site work, including installations needing scaffolding or a boom lift, and we are BCA-LEW licensed, so any mains connection is made by our own licensed electrical worker.
