Changing vertical menu

I’m very new to this thing and as first job I’m planning site for industrial company which offers parts for other companies. I’m not sure is it possible with WP to have many menus in way I want to have them. I want to have basic horizontal top menu with different industries. Then when you click say “metal industry” it would open below main page for “metal industry” and has vertical menu on side with different parts, where you can then click one and it opens page with info on those parts. So the vertical menu would change depending what you choose to click on horizontal top menu.

as you can see I’m bit confused how many different menus you can have at same time, or can they change depending where you click on main menu. Or would it be wise to have parallax site, with top menu always following. and when you choose for example that “metal industry” it would just jump down to that page and has those links for different parts there. So there wouldn’t be one side menu bar, rather one for each page?
