The kit ships to you disassembled and in raw steel form.  You will need to paint and assemble the bed during the install process.  You can either assemble it and then have it painted or you can have the parts painted individually and then assemble.  We chose to assemble ours completely and then paint to reduce the chance of scratching the fresh paint when installing the new bed. We highly recommend the assemble and then paint method.
