Steel-wood bookshelves are a common type in modern libraries, made of cold-rolled steel and wooden panels. They come in single-sided and double-sided versions. The standard shelves typically have 6 layers, though some are 4 or 5 layers. Features of steel-wood bookshelves include a small footprint, adjustable shelves, and the capacity to hold a large number of books. Standard dimensions are 2000*900*450mm, with a structure that consists of a main frame and a sub-frame. The main frame has pillars on both sides for independent use, while the sub-frame has only one pillar and requires the main frame for use. They are commonly used in libraries, bookstores, offices, and homes. We can customize them to meet your needs.
