Metallurgy suitable for Hot dip galvanising and how Si affects ?

[Ratheesh_n]

How the metallurgy of substrate affecting hot dip galvanising ?

What should be the % of silicon and Phosphorous in substrate which is to be hot dip galvanised ?

Does the higher Si & Ph % results in higher coating and grey shade ?

Thanks @Maui . It was very helpful.

But it doesn't mentioned about what will be the Maximum % of Silicon required ?
Usage of Tin as an additive to control the effect of silicon upto .034% is ok. So can we use upto 0.034 or lesser ?

Is phosphorous + Silicon content upto 0.04% will an ideal option ?
