Metal bunks beds are very popular, particularly since they are typically less expensive than wood bunk beds. Most metal bunk beds are manufactured in Taiwan, Malaysia and Mexico and are sold in the U.S. by importers and retailers. Tubular metal is used to construct these beds and they are often painted with high gloss black, white, red or blue paint. These metal bunk beds typically sell for between $150 and $250 each. With metal bunk beds, both the frame and the ladder are constructed of metal.
