Sturdy Intermediate Bulk Container Covers – Always a Good Fit!

American Machining manufactures never settles for anything less than a perfect fit. Our IBC Covers are guaranteed air-tight and leak proof, and are designed to take a beating. AMI’s IBC Lids are made from standard 16-gauge or our heavy duty 10-gauge 304 or 316 stainless steel, 3 times thicker than other IBC tank covers. The heavy gauge steel allows the welding of any combination of custom fittings with little to no worry of warping, which happens with thinner Portable Tank Lids.  The installation of vents, ports, and agitation unit’s to our covers, will insure optimum performance and safety.

Our Custom Designed IBC Covers offer hundreds of possibilities and options when it comes to the installation of special fittings; like filling ports, safety vents, and agitators.  Fittings that are milled to fit flush to the underside of the lid and are fused welded on the bottoms of the Portable Tank Covers. Flush fits, polished welds, and a standard 2B finish insure minimal collection points and cleaning ease. AMI also offers even a smother, custom-polished Tote® Cover, and an Electrochemical polishing option.


Our venting on the standard IBC Covers in order to meet UN31A regulations is accomplished by FUZ-VENT (the most popular fusible IBC Cover Vent) or a S/S vent if required. All vents for IBC Covers are found in the parts section of this site.
