Heat affecting on metal pieces cleaned by laser method

Heat affecting on metal pieces cleaned by laser method

(OP)
I am considering to apply laser cleaning method for touch-up painting of some special items which are long galvanized bars of 2mm thickness.
I have never done it before and I worry that the heat of the laser beam may cause a deformation on the thin bar items.
Can anyone advise me the temperature that the laser beam can heat up the items, supposing that 2000w machine will be involved in.
Warm regards.
