Fixing is easy using the Straight Line Clip which is exclusive to Mack Bros. All metal sheeting is subject to thermal expansion. This means the colour of the sheeting will effect the amount of thermal expansion. Together with the Straight Line Fixing Clip, our 406 range has proven to have excellent resistance to the problems associated with thermal expansion.
