Iron-zinc alloys- alloyed coating of iron and zinc

for easy painting and particularly resistance

welding.

Note 1. The mass of zinc is not always equally distributed on both surfaces of the sheet. However, it can

normally be expected that not less than 40% of the specified minimum coating mass, as determined by

the single spot test, will be found on each surface.
