hi Ken,
I'm sorry to hear of your house fire, With your aluminium climbers have them tested by the manufacture before you discard them, My experience with aluiminium when exposed to a heat that will damage them there's no mistaking the damage they simply collapse to a blob like form.Have them tested first before you throw them it might save you buying new ones.Think about it they can weld al, To weld al you have to melt the alloy to get fusion and it still has it's structual integrity. Just have them professionally inspected first.
