MMI Tanks are the strongest on the market, building them to fit perfectly into your facility is just the way we like to do business. If you are looking for a clean, sleek rectangular tank for your flammable liquids, our UL 142 rectangular single wall tank is a great option.

If you’re fitting it into an indoor space, whether vertically or horizontally, we can customize it for a perfect fit. The single wall is ideal for internal use, where it won’t be in danger of being bumped by heavy machinery, or exposed to the elements. Despite only having 1 wall, it’s still built strong, with between 7gauge and 1 ¼ inch thick high quality steel walls. Each seam is welded with a fillet weld to provide consistent strength under pressure.

  • If your vertical tanks need ladders, stairs and or platforms to make them accessible to your team, we can incorporate that into our design and fabrication, so they will fit into your available space.
  • If you need horizontal tanks, we can mount supports, skids or platforms as necessary to give them a firm fitting.

We build our tanks to last at MMI, before sending it off, your UL 142 rectangular single wall tank will receive a special coating to prevent wear and tear, like corrosion, and pressure tested. With MMI on the job, you’ll be running smoothly for years to come.
