Redwood timber for making a gate. Longevity outdoors?

[William Clifford]

Hi,

 

My father's looking at making a driveway gate and I've been potentially offered some Redwood. Not sure yet if it is Giant, Coast or Dawn.

 

How do they fair outdoors over a longer period of time (treated)? Posts will be galvanised metal so no wood in the ground, minimal joints to avoid potential water collecting / areas to rot. Are any of the above 3 Redwoods particularly good or bad as timber for outside use? He's preferred Cedar in the past but I seem to have a recollection that Redwood is also good?

 

Thanks.

Yes redwood is durable outdoors.  The sapwood not so much of course, but similar to cedar I would say.  I don’t have personal experience of dawn redwood but as it is closely related I would bet it is similar.
