JJI Design is the new design software platform created by James Jones & Sons Timber Systems Division to make using, specifying and designing with JJI-Joists even faster and easier.

To support all registered JJI Design users, we have created our own online Knowledge Base.

The Knowledge Base is a library of useful information and FAQ’s about the JJI-Joist System, its application and the JJI Design software’. Knowledge Base is only available to registered JJI Design users.

If you are a registered user of JJI Design and would like access to our Knowledge Base please email jjidesign@jamesjones.co.uk to request registration and access details.
