Galvalume vs. Zincalume

adv. pointer      


We are an architecture firm in So. Cal. and we are working on a light commercial building. In reviewing material submittals we have been given a sample labeled Galvalume Plus which the contractor says is the same as our specification for Zincalume.

What is the difference, if any, between these two finishes and which performs best when left exposed to weather (i.e. unpainted)?

Galvalume is licensed to Steelscape, Inc. They manufacture it under the name "Zincalume." In other words - it's the same thing.

You may want to talk to Bethlehem Steel, they may disagree........

Galvalume is licensed to BIEC (Bethlehem Steel) of Vancouver, Washington.

Zincalume is licensed to Bluescope of Australia. Steelscape is owned by Bluescope.

I would like to know, if I want to use one of them (Galvalume or Zincalume) with concrete, which one is better in order to minimize the corrosion?
Thank you.

Hi, Teddy. It sounds to me like people are saying it's two different licensed names for the identical process. But at this point, contact the two suppliers and see which you wish to buy from if you even have a choice. You may find that the product is not suitable for use with concrete :-)

Good luck.

Both are same. Its Galvalume that's produced under the name Zincalume licensed to BIEC, which is a subsidiary of Bluescope Steel, Australia. The JSW ISPAT industries in India has license from BIEC to produce Galvalume.

Hi, RR. If I have misunderstood, sorry, and please clarify ... but since Zincalume is a licensed product, it's only Zincalume if you prove it through a purchase order/labeling trail. Just as there is no software test to prove that a software program was licensed by Microsoft and is not a bootleg copy, it seems to me that there will be no chemical or metallurgical test to prove that a coating is Zincalume.
