Planning a small HDG plant

Q. We are in the process to start a new plant in Scandinavia.
Due to our location the market should be pretty good. We have a company doing a market analysis and so far it looks good.
How much will be produced is still not clear, but I think it must be expected it will be a small plant.
I have a lot of questions and worries and a major one is the chemical part of the operation.
Is it possible to this without years of experience as a chemist?
After a lot of research I have an impression that the chemical part will be the biggest challenge.
How much time and research should be expected during the daily operation?
I have also experienced that it's not easy to get in touch with suppliers of equipment, probably because we are in the early stage and they don't want to waste time.
I found this page very informative and I highly appreciate any feedback.
Regards,
Emil

A. Starting a new plant can seem like a big undertaking, and yes getting the chemistry "right" (effective and efficient) can seem tricky, but it's not so difficult. I often come across plants that don't pay enough attention to the chemistry of their pretreatment, and of their zinc, and the result is poorer quality at high expense.
But it doesn't take more than about an hour a day to keep these aspects under control. The changes are often small, but frequent. It goes wrong when making big changes and not very often. Most things in galvanizing are "a little and often".
