2. Glulam In Australia
Australia has a long history of timber buildings
Glulam has been a part of that history for many
years and has been used on some very unique
projects.

11. • In Europe and North America there exists:
• A cultural attitude towards a preference for timber in both
structural and non-structural uses.
• Climatic conditions that forces sporting activities indoors
• There is an established and recognised third party certification
schemes providing the customer with confidence in both the
image of the industry and the quality of Glulam.
• No similar scheme existed in Australia prior to the
establishment of the GLTAA.
Glulam In Australia
12. • In 1989 The Glue Laminated Timber Association of
Australia (GLTAA) was formed
• The GLTAA set Industry Standards and implemented
a code of practice
• The GLTAA quality mark ensures designers and
builders they can rely on the Glulam product to
perform to specification.

The use of deep section laminated timber
beams was identified very early in the design
process as a means of providing an efficient
and low maintenance structural system to
span over the salt water laden indoor
pool enclosures.

Solid timber beams allow many different connection
types to be used:
• Bolted –
Steel Plates to the outside faces of beams
Slotted with steel plates inside the beam
Flitch plates with steel plates between multiple beams

Editor's Notes
Engineered Glulam continues to meet the growing demand for a more dependable, sustainable, versatile building material that reduces our carbon footprint.Environmentally Responsible – Feed stocks sourced from managed forests and plantationsUser friendly. Light weight, easy to cut and drill make Glulam beams simple for any builder to erect. No special skills and only traditional carpentry tools are required, minimising the number of sub-contractors required on site.Flexibility in Design. Glulam can be used in almost any manner. As Beams or Posts, Structurally or for Aesthetics only and Glulam can be curved without loss of strength. High strength to weight ratio means smaller and lighter members are required to perform the intended task.Chemical and Acid resistance. Glulam works well in harsh environments, as it is not corrosive. Well suited to use in chemical stores, acid plants, salt-water environments and swimming pools. High strength to weight ratio means smaller and lighter members are required to perform the intended task.Chemical resistance. Glulam works well in harsh environments, as it is not corrosive. Well suited to use in chemical stores, acid plants, salt-water environments and swimming pools. Fire resistance. Glulam performs well in fires, charring the outer few millimetres of material but continuing its structural function. With correct design Glulam can perform better than some other products.
These beams are ideally suited to Indoor applications where strength and aesthetic qualities are important.
Not listed in AS1328 or 1720 are two additional beams –
Hyne Beam 17 Reinforced is reinforced in the upper and lower glue line with deformed steel bar. The F28 Steel Bar is encased in a machined void with high strength epoxy resin injected to create a physical bond with the timber and a mechanical bond on the deformations on the steel bar.The Epoxy Injection System ensures the Reinforced Beam will perform utilising the combine properties of the steel and the timber.Additional properties are available from Hyne Timber or can be found in Hyne Design software
Cambered Beams – with inbuilt camber reduce the amount of deflection in the installed beamCamber can assist in reducing beam depthCamber allows for wider spacing of structural members while maintaining similar depths to Non Cambered Beams.Australian Glulam Producers offer Straight Beams Ideal for Columns and window Mullions and TransomsAustralian Glulam Producers offer:Curved Beams – Radius of the beams will differ by producer and species of timber used.As a guide Hyne can curve Pine Laminated Beams to appx. 4.0m – Length limits might also apply for tighter curved beams.
Glulam offers the warmth and character of the timber being usedGlulam provides the strength and characteristic design properties to allow timber to be used on its own in in harmony with other productsGlulam provides design solutions to buildings with long spans, tall columns or curved membersGlulam is durable when correctly specified and detailedIf you can use timber you can use GlulamAdd Glulam members to TCC systems to areas where appearance is more important.Include timber to steel projects for the benefits only timber can provideDo not limit your project to just one material.Speak to your Producers and Fabricators early to ensure the right timber solution is found that meets the Structural, Aesthetic and Cost requirements of your next project.
