'Other' Constructional and Allied Systems Info & Downloads
Database of Metal Constructions Systems
Alongside his Other Systems Newsletter (OSN) Tony Knowles has produced a database of all known Metal Constructional Systems and their most important parameters. By his kind permission, his database is now also available on this website. You can search this database using a number of different parameters as shown below. Note that more than one parameter can be selected at the same time.
Note that the bug which prevented results being displayed when a date range was selected has now been fixed.
