Is European oak suitable for structural applications?

Yes, European oak (Quercus robur and Quercus petraea) is one of the strongest native European hardwoods for structural use. It achieves strength class D30 to D40 depending on grade, with characteristic bending strength of 30–40 N/mm² and mean modulus of elasticity around 10,000–12,000 N/mm².

Its natural durability class 2 rating means it can be used in exposed conditions without chemical treatment, making it ideal for bridges, external frames, and heritage restoration.
