I am looking at designing a gate to a cave and would like some advice on strength. I am considering using 3mm thick steel sheet with 10mm dia holes on a 15mm triangular pitch which gives 40% voidage. The question I have is what is the maximum distance I can have between flat bar supports to permit the sheet to withstand a pseudo point load of 200kg? (That is a stag stepping on the near horizontal gate; fortunately I don?t have to worry about cattle.) And, of course, what would be the minimum dimension of the flat bar to provide that support?
Many thanks in anticipation
