Every Egger OSB section

All 39 Egger 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.

Every section below is built into the calculator. Enter your span and loads to see whether the section passes, and by how much.

Frequently asked questions

What sizes does Egger OSB come in?
Calcs.com carries 39 Egger sections across OSB 4 TOP, OS'Brace, OSB 2, OSB 3 / Ergo and OS'Floor. Depths run from 6 mm to 40 mm (6, 8, 10, 12, 14, 16, 18, 20, 21, 25, 30, 40 mm), in breadths of 1000 mm. Every one of those sections is selectable in the calculators listed on this page.
Is there a span table for Egger OSB?
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 Egger 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 Egger OSB 4 TOP?
OSB 4 TOP is published with approximate density 620 kg/m3. Characteristic bending strength varies with depth, from 20 MPa to 25 MPa across the sizes in the table above. Values are taken from Egger OS'Brace Technical Data Sheet (2020), Egger OS'Floor Brochure (2019), Egger OSB 2 for Packaging Brochure (2019), Egger OSB 3 Brochure (2018) & CE Declaration of Performance and Egger OSB 4 TOP Brochure (2019), so check them against the manufacturer's current design guide before you rely on them.
What are the characteristic values for Egger OS'Brace?
OS'Brace is published with modulus of elasticity 4,500 MPa and approximate density 600 kg/m3.

What are the characteristic values for Egger OSB 3 / Ergo?
OSB 3 / Ergo is published with modulus of elasticity 4,930 MPa, characteristic shear strength 6.8 MPa and approximate density 600 kg/m3. Characteristic bending strength varies with depth, from 14.8 MPa to 18 MPa across the sizes in the table above. Values are taken from Egger OS'Brace Technical Data Sheet (2020), Egger OS'Floor Brochure (2019), Egger OSB 2 for Packaging Brochure (2019), Egger OSB 3 Brochure (2018) & CE Declaration of Performance and Egger OSB 4 TOP Brochure (2019), so check them against the manufacturer's current design guide before you rely on them.
What are the characteristic values for Egger OS'Floor?
OS'Floor is published with modulus of elasticity 3,950 MPa and approximate density 620 kg/m3. Values are taken from Egger OS'Brace Technical Data Sheet (2020), Egger OS'Floor Brochure (2019), Egger OSB 2 for Packaging Brochure (2019), Egger OSB 3 Brochure (2018) & CE Declaration of Performance and Egger OSB 4 TOP Brochure (2019), so check them against the manufacturer's current design guide before you rely on them.
Does Calcs.com support Egger products?
Yes. 39 Egger 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.
