Greenbarnes' produces durable, entry-level flat plate aluminium signs constructed from 3mm-thick aluminium sheet, which is more robust than equivalent signs in most plastic or composite materials.

Flat plate aluminium signs are available in standard sizes ranging from A4 (297 x 210mm) up to 1800 x 1200mm and, in most instances, a choice of shapes, including rectangular, gable, bow-topped, round-topped and gothic.

Sign panels are available for wall-, railing- or post-mounting. Wall-mounted versions are supplied ready-drilled and complete with screws and wall plugs. Railing- and post-mounted versions come complete with 2 or 3 runs of aluminium 'U' channel riveted to the rear face to accept fixing clips, which are also supplied.

The front faces of flat plate signs can be finished either in coloured vinyl (in a choice of 16 shades), providing the ideal background to take computer-cut vinyl lettering, or, for more complicated graphics, with a full-colour digital print. The latter technique also lends itself to the application of an anti-graffiti laminate in instances where this is deemed to be prudent.
