The safety of cages/travel cages

[Joolesgreyuk]

I have just purchased a travel/holiday cage for Beau however I became slightly concerned when assembling it as my hands became dirty from the metal. I know some birds suffer from metal poisoning and am now worried about using the cage. It looks to me like steel (not stainless) and more worrying for me is that it says "made in China" on the box - never a good sign lol. Can anyone tell me which metals can cause poisoning in birds? Thanks.
