The TimberLab 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, designers, 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.
