Post & Panel Sign System*  All Plastic, exterior, modular, extruded sign system

WhiteLight Design in Atlanta offers post and panel sign system development, sign planning, wayfinding design, wood, sculpture, monuments.  Working closely with the leadership, the all plastic post & panel sign system was inspired as an exterior venture extension for Innerface Sign Systems, a maker of interior signs.  The system consists of a cut to size custom extruded post made of formally GE Plastics, (now owned by Sabic) Sabic – Geloy® polymer material exhibiting the necessary mechanical strength and weatherability, with an interlocking sleeve extrusion and modular foamed plastic panel size.

The project included working with the GE Plastic Engineering group to produce an FEA – Finite Element Analysis report to qualify the plastic extrusion and material choice polymer post and panel could withstand the defined minimum wind loading. The extruded post and panel sleeve system was a success.  Ultimately, the modular sign system moved to a welded steel base plate footer and formed aluminum panels based on the FEA reports testing.

Hired specifically to lead this project,  Mr. Whiteside pen and inked on vellum, fully dimensioned production drawings documentation – for production release. The specifications document was a major step forwarding the Industrial Design career of Mr. Whiteside in product development.  We believe this was one of the first all plastic exterior extruded sign system to be produced, launching Innerface into the exterior sign market.  *work performed with Rupert Jensen Associates, Atlanta, GA
