what mm ali to use?

[AshG]

crumbs i got mine at the right time then. looking at the receipt paid £106 including delivery for 3 8x4 sheets of 1.5mm 5251 H22.

yes i did all my panels in hard ali. i didnt know how hard it was at the time just took the bloke on the phones advice, it was wrong and yes it blooming hard to bend.

my floor is 1.5mm 5251 H22 riveted every 2.5 inch and bonded. its so strong i can jump on it.

remember most tintops only have 0.9mm thick steel flooring
