Abstract

There is provided a method of making a metal panel assembly, the method comprising: - providing a first metal panel (10) having a first body portion (11) and a first flange (12) along a margin of the first body portion adjacent a first end (13) of the first body portion (11); - providing a second metal panel (20) having a second body portion and a second flange (22) along a margin of the second body portion adjacent a second end (23) of the second body portion; - providing an elongate adhesive sheet (30) having a first portion (32) near a first end (31) of the width of the elongate adhesive sheet (30) and a second portion (34) near a second end (33) opposite to the first end of the elongate adhesive sheet (30), the elongate adhesive sheet (30) comprising a thermosettable composition, the elongate adhesive sheet (30) having on at least one major surface a plurality of microstructures; - applying the elongate adhesive sheet (30) to said first (10) or second metal panel (20); - folding the first flange (12) of the first panel (10) over said second flange (22) of said second panel (20); whereby a metal joint is obtained wherein the elongate adhesive sheet (30) is folded such that the first portion (32) of the elongate adhesive sheet (30) is between the second flange (22) of said second panel (20) and said first body portion (11) of said first panel (10) and the second portion (34) of the elongate adhesive sheet (30) is between said first flange (12) of said first panel (10) and said second flange (22) of said second panel (20) ; - heating the metal joint so as to cause thermosetting of the thermosettable composition of the elongate adhesive sheet (30), thereby adhering said first (10) and second metal panel (20) and sealing the metal joint.
