Many customers, both new and existing are surprised when they discover all our letters are fabricated by hand by our expert craftsmen, rather than a line of automatic letter benders. You can read more about our Letter Workshop here.

Built-up letters are created using a variety of methods at SignFab in metal or acrylic.   Built-up letters are created from a choice of the flat-faced, rim and return rimless, bevelled and prismatic letter styles. SignFab’s built-up letters are available in Premium metal, Standard metal and acrylic options depending on project requirements and are used for shop signs, display signs, wayfinding signs and directional signs.

There is a wide variety of Built Up Letter Styles:

Rim and Return Letters
Rim and return letters get their name from the stroke or rim that meets the face material, which is usually around 20-30mm in width.

Rimless Letters
Rimless Letters allows the face material, usually and opal acrylic, to sit flush to the return of the letter which gives the impression of a free-floating face.

Bevelled and Prismatic Letters

Halo Letters
When built up letters or built up logos are combined with internal illumination and the faces remain opaque a halo illumination effect is produced.

Letters are created in a variety of materials with SignFab’s offering; aluminium built-up letters, stainless steel built-up letters, acrylic built-up letters with a wide range of paint styles including satin, polished and brushed finishes and RAL or Pantone paint processes, all within our in-house paint workshop.
