Description

Red Stag GLT beams are used as individual structural components (e.g. beams, rafters, lintels (roof and floor), ridge beams, columns or frame elements).

Red Stag Glue Laminated Timber Beams are engineered wood products made from H1.2 or H3.2 treated, finger-jointed and laminated layers of machine graded, kiln-dried and dressed radiata pine, pressed together with an adhesive under pressure to form one singular structural member.

Red Stag manufactures traditional Glue Laminated Timber (GLT) and bricked Glue Laminated Timber GLT (Vertix and GLTh). Vertix products are designed so that the lamella (boards) is orientated vertically in application. GLTh has lamella in the same orientation as traditional GLT so the boards remain horizontal in application.
