We have a large variety of Steel Flat File Cabinets made by Safco and Mayline. Steel flat files are very large cabinets made for the purpose of storing blueprints, poster storage, map storage, and almost any large flat document you can think of and may have. File files work great for protecting large documents from light and damage, and they work great for organizing blueprints and drawings with various projects being stored and archived in separate drawers. Safco flat files and Mayline flat file cabinets both are very well known brands in the industry. They are both made to last with quality in mind, and are backed by a limited life time warranty. EngineerSupply is a Premier Authorized Dealer of both Safco Products and Mayline.
