Advantages
Superior strength-to-weight ratio - approximately 900kg CO2 stored per m³Dimensionally stable with minimal shrinkage and warpingAvailable in lengths up to 18m with consistent propertiesEasily machined and modified on-site with standard toolsRenewable resource from certified sustainable plantationsFire resistant with predictable charring rateCost-effective compared to steel for many applicationsAesthetically pleasing natural appearance when exposedCompatible with standard timber connectors and fixingsLocal manufacture reduces transport emissions
Cautions
Susceptible to moisture damage if not properly protectedRequires preservative treatment for weather-exposed applicationsLimited in very high load or long span applicationsQuality dependent on adhesive bond integrityNatural variability in timber properties between batchesTermite susceptible without appropriate treatmentUV degradation of surface if left uncoated externallyTransportation limitations for very large sectionsRequires skilled installation for complex connectionsHigher initial cost than solid timber alternatives

Radiata Pine glulam production in Australia commenced in the 1960s following European technological developments. The establishment of AS/NZS 1328 in 1998 standardised production requirements, with the GL grade system introduced to harmonise with international standards. The Glued Laminated Timber Association of Australia (GLTAA) formed in 1993 provides industry quality assurance. Recent developments include mass timber applications and hybrid steel-timber systems, with Australian production capacity exceeding 50,000m³ annually.
