Woodspan Glulam

Glue laminated timber, also abbreviated to Glulam, is a type of structural engineered wood product constituted by layers of dimensional (finger jointed or solid) timber bonded together with durable, moisture-resistant structural adhesives under controlled pressure and heat. The result is a strong, stable and corrosion proof product that provides a natural alternative to steel or concrete while also delivering an attractive, warm and natural finish to your construction project.

Woodspan provides a range of New Zealand made Glulam beams and posts for use as structural support in roofs and floors and other applications. Our glulam is made to order, and can also be provided cut to length and/or CNC processed if required.
