55-Gallon Open-Head Steel Drum to ICC Specification 17H (1964)
The open-top 55-gallon (208-litre) steel drum, built to the rule US railways and shippers used for single-trip removable-head drums: welded low-carbon steel body, three rolled hoops, a crowned bottom, and a lid clamped by a bolted ring over a gasket.
Source: ICC Specification 17H, 49 CFR 78.118, Federal Register, 29 December 1964. The spec does not say how the bottom is joined. The litre figure, the gasket rubber and the machines are ours. Picture drawn by Youblob.

Cut low-carbon steel sheets
Cut low-carbon steel sheets
Use low-carbon steel for body and heads. For a 55-gallon drum: body 18 gauge, bottom head 18 gauge, removable head 14 gauge (16 gauge if the cover has one or more corrugations near its edge). 18 gauge is 0.0478 in nominal and at least 0.0428 in; 14 gauge 0.0747 in and at least 0.0677 in, measured at least 3/8 in from an edge.

Make the bolted ring and gasket
Make the bolted ring and gasket
Make the closing ring from 12-gauge steel with drop-forged lugs, one of them threaded, and a 5/8 in bolt and nut (for drums over 30 gallons). Fit a gasket under the lid: gaskets are required.

Check capacity and mark
Check capacity and mark
The drum must hold at least 4 % more than its marked 55 gallons, and no more than 5 % more (or 4 % plus 1 quart, whichever is greater). Emboss the marks: ICC-17H, STC (single-trip container), the maker, and the gauges, capacity and year.

Leak-test every drum
Leak-test every drum
Test each drum by air pressure inside of at least 7 psi with its seams under water or covered with soapsuds or heavy oil. Reject leakers, or repair them the way they were made and test again.
