How good is white redwood for a gate?
 
I just completed a gate. I bought white redwood for the 2X4s and the 1X6 pieces for the material.

Is this stuff better than douglas fir and the cheap cedar, as far as bug and rot resistance? I know it is not nearly good as the red heartwood, but I assume it is better than some other woods. It is a bit more expensive than the bottom of the line stuff.

I'm not familiar with white redwood, but I imagine it is just the outer sapwood that is close to the bark. I think it would have similar decay resistance properties as the heartwood due to the levels of tanic acid in redwood.

My take is that it is the sapwood also. I have never heard of "white redwood" Unfortunatley if this is the case, the sapwood is pretty poor when it comes to deacy resistance, just like the sapwood in western red cedar.

Or it could be some creative marketing name for something totally unrelated to redwood at all, one of the new popular things that is high on my list of pet peeves that swells my n**s bad. .... "Phillipine mahogany"--there is no such thing, the species is meranti and the only thing that it shares with mahogany is the redish color and open grain look. "Chilean Sea Bass".. the species is Patagonian Tooth Fish and the ony thing it shares with bass is maybe a spot in the same freezer at the distributors warehouse. "MacRib" sandwich:censored:

I think it is sapwood. The pieces are variable in color, some areas reddish, some areas white. It is cheaper grade redwood, it was much work sorting through the boards to find pieces with fewer knots and no cracks.

I'm just hoping since it costs more than the bottom of the line stuff (douglas fir 2X4s and cedar 1X 6s) that this redwood sapwood is at least tougher than the bottom of the line material.

Cedar and Douglas Fir aren't on the same page as far as decay resistance in an outdoor application. The Cedar will outperform Fir, hands down. Cedar would be a great option for a gate.

If it is to stay unpainted, I would give it a liberal application of water sealer every year to get as much life as possible from it. If it takes a lot of sunlight, once in the spring and once in the fall ( 15 minute job) will help greatly. Pay extra attention to saturating any points where there is wood to wood contact.

The same attention to the grade of the cedar applies as we are talking about in this thread. Just because it is cedar, doesn't automatically make it deacy resistant. If it is full of sapwood, it will decay as fast as a piece of pine or anything else.

Yup! :thumbsup:

Then I'll just be resigned to the fact that the extra money I spend was wasted, since I was hoping to make the gate a bit more decay resistant.

I did prime and paint each piece of wood before assembling it. But other painted gates and fences we own have rot and termite problems after five or six years, fairly quickly.
