Molten zinc only. However, hot dip galanizing requires at least an acid bath

hi

Is it possible to do Electroless zinc plating on steel?, if so pls what
is the bath make up?

I don't know of an electroless zinc, but electroplating zinc is quite
easy and takes very little electricity -- about 0.02 amps per square
inch of workpiece. The voltage is about 3 volts DC. Ammonium
chloride will work as an electrolyte. Commercial solutions have
"brighteners" but straight ammonium chloride will work; you just have
to buff it up a little if you want it bright.
