Glulam Span Tables

The Glulam Span Tables have been developed primarily for domestic applications in accordance with NZS3603 "Timber Structures Standard" and with the joint AS/NZS 1328:1998 standard "Glue Laminated Structural Timbers". The purpose of these tables is to make it easier for builders, draughtsmen, architects and engineers to come up with a quick and accurate design for Glulam beams. These cover the most common domestic uses for Glulam beams – roof beams, rafters, ridges, lintels and floor beams. At a glance designers and builders will be able to find the correct size of beams for a variety of spans at various spacings and loadings.

Primarily for domestic applications (roof beams, rafters, ridges, lintels and floor beams) in accordance with NZS 3603 and AS/NZS 1328:1998.

NZ Pine User Guide

The New Zealand Pine User Guide outlines suitability and versatility of New Zealand pine for a wide range of end uses.

Plantation grown New Zealand pine is a light coloured, medium density softwood with a moderately even texture that produces sawn lumber with excellent machining properties. The even texture and relatively small density variations across the grain in New Zealand pine provide excellent finishing properties, uniform acceptance of decorative stains and good paint retention.

New Zealand pine sawn lumber is a versatile structural building material which is well suited to the 2x4 building system. It is used equally successfully in larger buildings as glue-laminated lumber and engineered wood products such as “I” beams.

New Zealand Pine is also being successfully used for a wide range of appearance grade applications, ranging from interior fittings and fixtures (windows, doors, frames and jambs, mouldings, stairs, cabinetry and bench tops), exterior building products (fascia, weatherboards, handrails, balustrades and door jambs) and furniture and furniture components.

The increasing availability of plantation-grown pine has enabled the New Zealand forest industry to expand its production of semi-processed and fully finished products for export.
