London to barcelona

I need to ship a day-bed frame and base from London to Barcelona. It is made of metal- some bits steel other bits cast iron. It collapses into several flatish (greatest depth approx 50 cms) pieces and so could be put into a box measuring roughly 150 (w) x 100 (h) x 1.80 (L). Are there companies who could box it and send it for me? Is it even necessary to box it? Might I be able to put it as a part load in a removals lorry? Would anyone be able to reccomend the best way to send it, and any good reasonably priced companies. I am English but live in Spain, and speak both languages so am happy to use either an English or Spanish company. I need to send it around 12 13 th March- if necessary I can wait a month for it to arrive. Many thanks.
