Metal
A metal IBC is a carbon steel or stainless steel tank. It is often UL 142 listed and it is the build for fuels and flammables that plastic should never hold: metal IBCs are suitable for onsite storage of Class I flammables and Class II and III combustibles.
01Carbon steel and stainless
Carbon steel is the cheaper choice and suits fuels and many solvents. Stainless steel resists corrosion, so it suits products that attack carbon steel and some food and pharma uses. Both are heavier than a caged composite and both stand on their own frame.
Many are listed to UL 142 for aboveground tanks. The listing matters for onsite fuel storage, where your fire marshal decides what is allowed.
02Fire performance
Metal IBCs can withstand fire for at least 30 minutes if they are equipped with a pressure venting device. A plastic IBC holding a combustible or flammable liquid can melt or burn fairly quickly and release its whole contents. That is the difference a buyer for a fuel job should hold on to.
03On a ticket
| Say | Why |
|---|---|
| The product it will hold | Decides carbon or stainless |
| Onsite storage or transport | The listing and plate differ |
| Whether it must be UL 142 listed | Your fire marshal may require it |
| Size and count | Metal IBCs come in sizes the desk does not list |
The desk matches fewer metal totes than caged composites. A ticket for one is read as a general inquiry first, and the desk says what it can find.
04Steel totes and their market
Metal totes are made of carbon steel or stainless steel and are used for products that plastic cannot hold: flammable solvents, hot products, and food or pharmaceutical products that need a surface that can be sanitised. A metal IBC can withstand fire for at least 30 minutes if it carries a pressure venting device, and metal IBCs are suitable for onsite storage of Class I flammables and Class II and III combustibles.
The market is smaller and the values higher. A stainless tote is bought for the metal as well as the use, and a UL 142 approval, the standard for metal totes used for long-term housing of materials, can matter to a buyer storing fuel or solvent on site. Metal totes still need their plates, and rigid IBCs are limited under 49 CFR to 3 cubic metres, 793 US gallons.
They also need an internal inspection at least every five years, like plastic and composite totes, and the plate shows the marks. A metal tote with a dent, a weeping weld or a seized valve is a repair job and not a resale one.
