We can even fabricate complete circles.
Curved laminated timber beams.
They resist checking and twisting because of the use of multiple plies of kiln dried lumber bonded together with waterproof phenol resorcinol adhesive.
Curved beams creativity involves thinking outside the square and wouldn t it be great to work with a material that allows you to do just that.
Radial curved elliptical shapes and reverse curves are all possible.
Our creative curves can turn a humble beam into an arch and open a box into an atrium.
As a rule of thumb the thickness of plank required is the radius 200 i e.
Rigidply rafters inc has been manufacturing glue laminated products since 1954.
Glulam beams that curve in plan use plies that are oriented vertically therefore the finished height of the beam is based on standard glulam widths.
Laminated beams are superior in all strength characteristics to solid sawn lumber.
The tightness of the radius will determine the thickness of the laminations.
Differing radii are achieved by adjusting the clamp layout and using different thicknesses of timber.
Use other member stress combinations e g.
The thinner the planks are the easier they are to bend which allows tighter radii to be achieved.
A nine metre radius will require a plank thickness of 45mm but a two metre.
The flexibility of glulam beams allows for the designer s creative imagination to be realised.
