Arched Glue Laminated Beams

We can manufacture most custom curved shapes including s curves side curves parabolic arches double compound curves and tight radius curves with.

Arched glue laminated beams. Glulam beams with constant cross section and radius for barrel or dome roof profiles. Rigidply rafters inc has been manufacturing glue laminated products since 1954. These tables are provided as a guideline. Our titan timber beams resist checking and twisting and are job site ready with one piece construction and more cost efficient than lvl and psl.

The flexibility of glulam beams allows for the designer s creative imagination to be realised. Boise glulam is a strong cost effective wood beam solution which can be used as beams or columns in a multitude of building design applications. A traditional 3 hinge arch design commonly used in glulam structures. Glue laminated glulam beams timber technologies glue laminated beams are superior in all strength characteristics to solid sawn lumber and pound for pound stronger than steel.

Laminated beams are superior in all strength characteristics to solid sawn lumber. Aitc capacity tables provide the uniformly distributed load that a glued laminated timber beam can support based on beam size span and material properties. The tightness of the radius will determine the thickness of the laminations. Aitc beam capacity tables.

Factory made members can be formed into any practical shape and any desired size. In addition to making curved beams american laminators can also manufacture beams with one side curved and the other side straight. The glue lines are usually exaggerated on the cut side. Apa certified for quality assurance.

Products work well in single or multi family residential as well as light commercial projects. They resist checking and twisting because of the use of multiple plies of kiln dried lumber bonded together with waterproof phenol resorcinol adhesive.

Our structural glulam units are available in columns trusses arches purlins and beams floor and roof. Use beam stress combinations e g. Curved beams and custom fabrication is available. Table specifications are provided with each table indicating conditions and assumptions used to calculate the loads.
