Since I have the land and I do enjoy smoking meat along with the rest of the family. I have been thinking of building a smokehouse.

I have seen many plans online but one thing I'm having a problem finding are the steel doors they are using on these smokers I'm not sure if they are custom made or if I'm not looking in the right place?

I'm going to have a huge amount of mesquite wood as soon as I start clearing brush around the home. So looking for more ideas on the build and plans but mostly looking were to get the heavy steel doors. Thanks!

Are you building a smoke house or a smoker?  That is to say are you trying to cold smoke meat (smoke house) or are you trying to cook meat (smoker).  No need for steel doors on a smokehouse.  I’ve used a wooden shed with the fire in a number 2 wash tub to smoke meat. Smoking meat is normally done at less than 90 degrees which can be difficult in Texas except in winter. Even smoking sausages is doe at 150 degrees or less. At these temps a wooden smoke house with an offset fire box works great. Now if you are trying to cook briskets, ribs or pork then you are talking 250 degrees and you need nonflammable materials.

With you question about smokehouse or smoker. I'm not looking to do cold smoking at all from what I was told why to much to go wrong!
