Hello Mark,
This is a great question. I can't recommend any specific vendors, but I can provide resources with considerations when planning for high density storage.
I agree with others in that that you will need to make sure there is space to remove boxes safely and get a cart between the shelves. I also like systems that have slide out reference shelves that act as a landing space for boxes/objects. I prefer manual systems for opening shelves over electric systems. In my experience, the manual and are very easy to move, are less likely to break, and collections will still be accessible in an emergency if the power fails. Electric systems tend to have more issues and break often. With electric systems it is essential to make sure all aisles are clear before moving the shelves as the power/weight of the shelves can crush anything in an aisle (once I almost got crushed).
Powder coater steel shelves are recommended. I also suggest finding a vendor that uses recycled steel to reduce the carbon emissions associated with manufacturing the shelving.
The Society of American Archivists produced a pdf on storage equipment that offers pros and cons and considerations for storage furniture, Section 6 - Equipment.pdf.

Everyone,
My organization is planning to build a new repository and wants to install high-density shelving. If you have experience with this kind of shelving, which vendors would you recommend?
