This R/P ligature has relevance to you company specifically. It is, simple, suggestive and versatile across any media. It will scale very well to any size large or small and print cleanly. The icon can stand alone and still be recognizable. The overall emphasis is on a company that sells products - you will not be mistaken for a commercial real estate brokerage.

Another idea relating the R and the P. It's an abstract amalgam of architectural shapes and surfaces suggestive of your product offerings. I welcome your feedback...
