Liimaristikko Oy and G-joist Oy are filials of Patenttitoimisto T. Poutanen Oy focusing on development of glued timber trusses and licensing the technology.
We have developed and patented the key embodiments of the glued timber truss technology.
The competitive advantage is normally 20%-30%.
A pilot plant is operating in Finland.
We look for licensees/partners to commercialize G-joist.
G-joist is the only trussed joist which can be manufactured as a long billet and cut to actual needs.
G-joist can be supported at the upper chord, at the lower chord or between the chords.
G-joist is the only trussed joist which can be manufactured for high loads to replace glulam and for
long spans up to 35 m (115 ft).
G-joist is the only one which may have an arbitrary mid support which enables simple and cheap
staircase and roof openings.
G-joist has an exposed version with no open routings.
