What sizes does NeXTimber glulam come in?

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.

Is there a span table for NeXTimber glulam?

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.

What are the characteristic values for NeXTimber GL13?

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.

What are the characteristic values for NeXTimber GL13C?

GL13C 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.

Does Calcs.com support NeXTimber products?

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.

Every NeXTimber glulam section

All 104 NeXTimber sections in the Calcs.com library, with the section properties and characteristic values used to design them.

These are section properties and characteristic values, not allowable spans. A span depends on your loads, member spacing, and deflection limit, so it has to be calculated.

SpecifyingGlulam & CLT

Specifying Glulam and CLT for Australian and New Zealand Projects

Engineered timber specifications are often written generically. When the section size on the drawings does not match what is stocked locally, builders substitute it out or send it back to engineering for re-approval, and the project loses weeks. The result is a design you no longer control at the build stage.
