Galvanised metal roofing is light-weight compared to tiles - the 
colour-bonding is a process that binds colour (paint) to the galvinised 
metal so it doesn't chip or peel. I'm not sure what the actual metal is - 
we refer to it colloquially as gal-iron or tin roofing. Maybe some other 
Ozzie with more knowledge can fill you in.
