Archival Shelving is specifically designed to store archival material. There are many common sizes including 42″ wide and 30″ deep so that efficient use of the cube can be made for archival boxes. For instance, the 42″ width allows for three boxes wide with little wasted space. The same is true of the 30″ depth which allows two archival boxes to be placed back to back. While the 30″ depth is more common you may want to consider the 32″ depth which fits most archival boxes even better. There are many other types of material that can considered archival and there are many specific shelving types for each one of them. Please phone us and we will be happy to recomend a good fit for your application.
