Commentary: Well most of the APV's and mechanicals are very solidly built. Since the Provari isn't an option you could consider a VAMO. They're chrome, and quite sturdy. Pair it with a pyrex cartomizer tank and you should have a reasonably sturdy setup for about $40-50 for the tube, about $30 for the tank and maybe $20 for a Nitecore i2 charger if you don't have one already, plus some good batteries that should run you about $8-10 a pop. I own a VAMO and I'm quite pleased with it, but if you're using it on a construction site you may also want to invest in a textured wrap, as most of these mods have a smooth finish which does make them a little easier to slip through a hand.
Or you could go with the even more durable mechanicals like the Silver Bullet or metal BOLT or SmokTech Natural. They can take a beating and keep on plugging, since there is no circuitry in them to be damaged from drops or whatever. The vape is slightly different from a regulated mod like the VAMO or Provari, but you should be able to find a pretty reasonable price on something like the BOLT.
As far as
tanks go, IBTanked pyrex tanks have had good
reviews as well as Phiniacs, as two suggestions. If you really like the clearomizers over the carto tanks (not sure what you've tried) the Kanger ProTank is pretty solidly built from what I've seen and has had generally good
reviews. It's pyrex and stainless steel I believe.
