i do have the stainless steel mesh.but i do not know what to use for the frame.
stainless steel is very expensive????
People usually use flat steel and angle iron for the frames. If you go to the builds forums someone can help you out.
You can use a thick wire mesh or an iron grid for the frame. I had used it once and it really works well. Try it out once and if you still can't get it we will find some other way. Best luck for that.
thank you very much. have a good day
