Processing Special Coated Metals: Galvalume

In this series we’ve been looking at the challenges and risks associated with laser processing coated materials. Today we’ll concentrate on galvalume.


Galvalume is a mild steel product that is dipped in aluminum.  There is really nothing too difficult about cutting it. Treat galvalume that same as you would stainless steel and cut with nitrogen.

Many fabricators have not had much success when trying to cut galvalume with oxygen. Just be sure to factor in some extra cutting time and run the job 15% to 20% slower than normal. 

It is not uncommon for the product to vary greatly from one supplier to another. There are times with when the thickness of the aluminum coating can vary quite a lot which will inevitably affect your pierce condition, cutting condition, feed rate and finished product.
