Duragal vs Allgal, what's the difference?
Allgal refers to something that has been galvanised inside and out through electrolysis, whereas Duragal refers to something that has been galvanised only on the outside.
All of our RHS/SHS is Allgal, galvanised inside and out. All of our angle and flat bar, however, is Duragal as it isn't hollow, so it is galvanised on the outside
