i used 3/16" p&o plate for the boxing plate. i'm not sure how much i bought so far. i would guess what i have used at 12-14 ft^2 but i have no idea. i buy it from work and i bought a partial at first and used parts of it and then i cut the funny shaped parts from a different sheet we had laying around at work. i am quite sure that a full 4'x10' sheet would be more than you need. for what i've made so far i would say i have spent 80-90$. keeping in mind i get the steel for barely more than cost
