What is Colour coated coil?
Colour Roof coil coating incorporates specific processes for each
type of substrate, has cleaning and pre-treatment
processes different for each input variation and a chemical dip
surface conversion process-specific again to each
metal and substrate coating.
What is the difference between Aluzinc and galvanized?
There is a visible difference between the two as an aluminum-zinc
alloy metal appears to almost have a matte finish.
Galvanized metal corrodes linearly, and eventually, the zinc
coating is completely depleted, whereas an aluminum-zinc
alloy experiences some corrosion, but on a smaller and less
significant scale.
