NeXTimber GL13 and GL13C glulam section sizes

Calcs.com carries 104 NeXTimber sections across GL13 and GL13C. Depths run from 126 mm to 630 mm (126, 168, 210, 252, 294, 336, 378, 420, 462, 504, 546, 588, 630 mm), in breadths of 65, 85, 115, 135 mm. Every one of those sections is selectable in the calculators listed on this page.

This page publishes section properties and characteristic values, not allowable spans. A span is not a property of the section: it depends on the loads you apply, the member spacing, and the deflection limit you design to, so the same section spans different distances on different jobs. Rather than reading a span off a generic table, select the NeXTimber section in a Calcs.com calculator and enter your actual loads. The calculator checks bending, shear, bearing, and deflection and reports the governing limit.

GL13 is published with modulus of elasticity 13,300 MPa, characteristic shear strength 4.2 MPa, compression parallel to grain 26 MPa and approximate density 520 kg/m3. Values are taken from NeXTimber® Glue Laminated Timber, so check them against the manufacturer's current design guide before you rely on them.

Yes. 104 NeXTimber sections are built into the section library, so you select them from a dropdown rather than entering properties by hand. They are available in 8 calculators, listed on this page.
