Secondly, steel is easy to form. If the production efficiency can't keep up, large-scale procurement will definitely not work. The efficiency of making library bookshelves with cold-rolled steel plates is very high, so pioneers can also mass-produce library bookshelves in the shortest time.
Thirdly, library bookshelves made of cold-rolled steel plates are stable and reliable. Bookshelves are load-bearing, so the materials should be reliable and not easy to deform, which is the design requirement, and cold-rolled steel plates are very advantageous in this respect. Moreover, the steel library bookshelf also has the characteristics of fire prevention and moth prevention, and can be used for a long time.
Nowadays, whether it is a school library or a bookstore, even some museums and archives have begun to use steel bookshelves.
