Can manufacture a variety of different types of curved glulams including the standard constant radius curve tudor arches and peak and cambered glulams.
One of the greatest advantages of glulam is that it can be manufactured in a wide variety of sizes.
Pitched and tapered beams taper from the tangent point to a minimum end depth to provide maximum economy.
Optimal roof pitch is 2 12 to 3 12 though other roof pitches are possible.
The tension allowed for the glued beams was 136 kg cm2 13 6 n mm2.
While this is true for solid sawn as well as glued laminated glulam timbers the larger sizes and longer spans made possible with glulam components make the proper detailing of connections even more critical.
