SGCC Dx51d Prepainted Galvanized Steel Coil 1250mm Z30-Z275 ASTM PPGI PPGL Ral Colour Al Zinc Coated Roofing Galvanized Sheet
What is galvanized steel coil used for?
The galvanized steel coil that most construction workers use is often found in roofing applications. There, it is used as
a protective cover or barrier over ridges and valleys in the roof system.
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.
What is Z275 steel?
The specifications Z275 and Z600 refer to the zinc coating, measured in grams of zinc or aluminium/zinc per square metre.
This measurement is the total coating mass on both sides of the steel.
