What boards do you use for a dock?

Excuse me, I'm curious to know about your approach to docking. Could you elaborate on the type of boards you typically utilize for this process? Do you prefer wooden boards for their durability and stability? Or perhaps you favor metal boards for their strength and resistance to corrosion? Additionally, I'm interested in knowing if you customize these boards according to the specific requirements of your docking application. Your insights into this aspect of your work would be greatly appreciated.
