Re: Average life of hive equipment
Well maintained, boxes (and frames) should last for a good long while, the issue being the frame ends of the box with only 3/8" of wood, which tend to get a lot of abuse. Foundation color will tell you when to retire them. Well used brood only lasts a few seasons, with the supers some years longer. But it is a matter of cost and opinion as well. There are some long time beeks that run on decade-old stuff.
I find that my older (frames) all tend to be wired and I don't feel like dealing with that so I retire them, but not until after they have turned a wicked color and are not servicable.
