Can glulam beams be curved?

Yes, curving is one of glulam's most distinctive capabilities. Laminations are bent to shape during manufacture before the adhesive cures, allowing single-radius curves, double curves, S-curves, and complex 3D geometries.

Yes, curving is one of glulam's most distinctive capabilities. Laminations are bent to shape during manufacture before the adhesive cures, allowing single-radius curves, double curves, S-curves, and complex 3D geometries. The minimum radius depends on lamination thickness: for standard 40 mm laminations, minimum radius is approximately 6–8 m; for thinner 20 mm laminations, radii down to 3–4 m are achievable. Tighter curves require thinner laminations, increasing cost. Curved glulam enables architecturally expressive forms — arches, portal frames, and free-form structures — that are impractical in solid timber or steel.
