Good timing on this post because I was going to ask the same thing about a month ago. A contact in Dubai tipped me off to Crateco and I have been happy since. What matters for your situation specifically is the closure ring design, it locks down evenly around the full circumference of the rim which is what stops that weeping around the edges when internal pressure builds up from heat. Imported drums often have rings that look fine but have uneven bite and that is where you lose product. The Crateco open tops are also sized to stack four to a pallet cleanly which makes warehouse organisation much easier.
