Reference for people who specify and install sign letters, written around the decisions that cost a second site visit.
Choosing 304 or 316 stainless for sign letters
The choice is set by chlorides in the air, not by budget, and getting it wrong shows as rust streaks within a year.
Minimum stroke widths and what actually limits them
A thin stroke hits three separate limits at three different widths, and knowing which one a design crosses is what makes it buildable.
Fixing methods by substrate
The wall decides the fixing, and the fixing has to be settled before the letters are fabricated rather than on the day.
PVD gold, chrome and coloured finishes
PVD is a vacuum-deposited coating measured in microns; chrome is electroplating. They behave differently outdoors and cannot be touched up on site.
Specifying LED channel letters that survive their warranty
The driver, not the LED, decides how long an illuminated letter lasts, and the face material decides how it looks when lit.
Send us the drawing
Send the artwork with the letter height, the finish you want and the surface it fixes to. You will get a material proposal, a price and a lead time, and we will say up front if a stroke is too thin to build as drawn.
