What are the disadvantages of ash?
Foremost is probably the fact that it is not as rot or weather resistant as other hard woods. Left unprotected, ash will deteriorate and rot fairly quickly. It does require periodic treatment to preserve its integrity and elasticity. Compared to a wood such as spruce or a synthetic rail system such as aluminum, ash is heavier. It’s up to you to figure out which feature is more desirable– weight savings or flexible strength.
