Curved Beams and Arches

Cranked Beams – These beams follow the roof pitch on their top edge while the bottom forms a radius curve. Cranked beams taper from the tangent point to a minimum end depth to provide maximum economy. They may be simply supported on timber or concrete posts.

Continuous Curves – Beams curved throughout their length provide consistent shapes for dome roofs and other complex forms.  Elliptical or regular curvatures can be achieved. Connection details can be included making for simple on-site assembly.

Complex Curves – Beams that move from straight line into a curved section or from one radius to another; even reverse curves can be easily catered for in glulam beams. The thickness of the laminates will be governed by the tightest curvature. These members enable unique shapes to be formed that would not be possible with other materials.

Inverse Curves – Upward curving beams provide a popular variation and can be made to form inverted arches.  These beams can taper through their length to cater for highly stressed areas. Care should be exercised in requesting a continuous lamination on the under surface if this is required for appearance.
