Pole & Plank & Signbox 78

Pole & Plank & Signbox 78

Simplex have a long and established background in supplying modular sign systems to the trade spanning over two decades.

Building on this experience, good and bad, we took the decision to design our own aluminium extrusion range with a view to producing the best on the market. The end result is a comprehensive range of products designed for ease of installation and strength.

Pole & Plank

It’s a generic name for the simplest of signs, a plank or panel spanning two poles. But not all systems are the same!

Our range consists of a round pole, a square post, a “D” shaped post, a quad slot pole (for double bank and 90 degree configurations) and a quadrant shaped walltrack. Into these components you can fit our 100mm, 150mm or 200mm extruded planks or have panels custom made to any size from 60mm upwards. For a more cost effective or temporary arrangement we offer our ACM holder for holding 3mm panels into our round poles. With baseplates, ball finials and shaped tops to panels there is something in the range for everyone!

Pole & Plank can also be used for fingerposts signs helping to keep your sign family consistent in appearance on those larger projects.

Signbox 78

This extrusion gives the opportunity to create small to medium sized monolith signs in a simple but striking manner. The 2mm face panels can be fixed or removable and can be fret cut and illuminated if required. Signbox 78 coupled with “D” posts to the sides gives the monolith nicely rounded sides. Alternatively, by utilising our framebuild extrusion the sign can be post free and more monolithic in appearance.

The whole range is available to you in a variety of formats; as stock component lengths for you to cut and fabricate yourself, as ready cut and fabricated ready for you to paint, or fully finished just requiring vinyling and installation. The choice really is yours.
