Oak Heavy Timber Joist (Sawn) – 200×70 mm – 3000 mm

Oak Heavy Joist

Our 200×70 oak joist is the deeper of our two oak joists, for longer spans, raised oak decks and frames that carry other joists. You get solid sawn European oak, Durability Class 2, in a section that looks substantial on show.

It comes in 3 m and 5 m lengths; a 5 m joist weighs about 50 kg, so plan on two people. The depth lets it work as the beam on a raised oak deck.

Where this size goes

Use it as the main beam or joist on raised oak decks and walkways, as a lintel on an oak garden structure, and as heavy stringers.

Lifting and bolting

Plan for two or three people on the 5 m length. Bolt it to oak or stainless post bases with stainless through bolts, pre drilled, and hang lighter joists from its face. The sawn face suits an exposed frame; an engineer should size it for a raised deck.

Where not to use it

For shorter spans, the 150×70 oak joist is lighter. For a deep softwood joist that is easier to lift, see the 200×70 Douglas Fir heavy joist. See both sizes in our oak joists.
