Glulam is manufactured using Pinus Elliotti (slash pine) from sustainable sources.

H1.2 Treatment

Glulam is treated to H1.2 meeting the strict New Zealand building codes.

Glulam Description

Glue laminated beams (Glulam) are solid wood members manufactured by bonding multiple pieces with proven adhesives to form a larger structural member. Glulam is more uniform and offers improved structural performance over sawn timber.

Lumberworx distributes GL17c manufactured by Megabeam located in Caloundra, Queensland, Australia. This product is utilises slash pine (pinus elliotti) with high stiffness in its manufacture and with the standard radius camber (see camber details below).

Megabeam commenced trading in 2011 on the Sunshine Coast, Queensland, Australia as a Glulam manufacturing and supply business specialising in GL17c beams. Megabeams managing director, John Schwabe has been glue laminating since 1990 and consulting as an engineer since 1988. John developed much of the Glulam manufacturing standard AS/NZS 1328 and developed the current grades that exist in Australia's Timber Design Standard AS1720.1.

The renowned natural strength of timber is enhanced by the glue laminating process, ensuring GL17c is comparatively lightweight and ideal for long span / high load applications. GL17c is ideal for lintels over large window and door openings, garage openings or roof beams where spans over large spaces are required.
