ABSTRACT OF THE DISCLOSURE Disclosed are aluminium sheets suitable for forming a structure of press-formed components secured together by adhesive and a method for producing such aluminium sheet. The sheet has an anodic oxide layer formed thereon by having been subjected to an anodizing process in an acidic electro- lyte for a period of 2 minutes or less and an adhesive compat- ible press-lubricant on the anodic oxide layer. The invention enables structures to be fabricated from aluminium components which have undergone a rapid pre-treatment but nevertheless gives rise to bonds of strength and durability compatible to those achieved using the Boeing process.
