I'm looking to build a smallish concrete block pit at the house. My question for you all is what type of expanded steel should I get? I've seen and researched 3/4 #9 flat expanded steel is ideal. My next question is where could I find a piece big enough for the pit? I'm thinking of having it 3ft X 5ft. The goal is to do a whole hog (a smaller one) in the traditional North Carolina way of just using wood. I'm originally from NC and have a love for eastern NC vinegar sauce whole hog cooked over only wood. If you have any ideas for basic designs for the pit, I am more than open. Thanks!
