Buy Used Plastic Drums in Mercer Island, WA

A 55-gallon HDPE drum is about 23.3" in diameter and 34.75" tall, slightly larger than the 22.5" x 33.5" steel drum, and weighs 20 to 28 lbs empty, roughly half a steel drum. A 30-gallon drum is 19" x 29" (13 to 16 lbs) and a 15-gallon drum 15" x 26" (8 to 10 lbs).

HDPE resists most acids, bases, and salts and does not rust, which is why it is preferred over steel for corrosive liquids. It is not suitable for strong solvents or contents held continuously above about 120°F, where steel is the right drum, and tight-head HDPE drums are UV-stabilized for outdoor storage.

A reconditioned drum has been cleaned and inspected and can hold product again when the new contents are compatible with the prior fill; hazmat use still needs a valid UN marking from a DOT-certified reconditioner. A used drum is sold as-is, with prior contents disclosed when the seller knows them, and suits compatible reuse or feedstock for a reconditioner. Damaged drums go to HDPE recycling; grade says nothing about head type, so check the 2" bung tight-head or bolt-ring open-head separately.

Only if it was food-grade to begin with, has been reconditioned, and carries the reconditioner's potable-water certification; a food-contact certificate alone does not approve drinking water. HDPE absorbs a fraction of what it holds, so a drum that held chemicals should not be reused for food or water regardless of cleaning; look for a 55-gallon drum whose listed prior contents were food or beverage.

The same floor layout as steel: 104 empty drums single-tier on 26 drum pallets, 208 double-stacked, 200 or more loose. Filled with water a plastic drum is about 480 lbs, so roughly 90 reach the 45,000-lb payload, a few more than steel.
