Produce and test safe sign structures to British and European Standards

KeyPOST One Minute Overview Video


KeyPOST is a sign structure software program that provides for the design of sign installations. Whilst many will use the AutoPOST feature that suggests suitable structures it can also be used to test their stability against the effects of wind loading by providing for existing structures to be modelled and tested, for example for additional or replacement signs.

KeyPOST is fully accredited by BSI against BS EN12899-1:2007 (May 2013 edition).

The latest release of KeyPOST 3.1 extends further support for BIM and 3D. This update includes the ability to incorporate the original sign drawing with your KeyPOST proposals to create a 3D sign structure in KeySIGN. In addition, you can author the data associated with the 3D sign structure to share with other BIM applications, such as Navisworks.

What People are Saying

KeyPOST provides the perfect solution for my clients needs. It gives me the ability to design with the flexibility to suit varying site conditions.

Alister Storey, Storey Design Ltd

KeyPOST is a significant step up from its predecessor, the inbuilt KeySIGN calculation module. Although a more involved process, it enables a much more flexible solution, and gives greater analysis output and better detailing than previously available.
