Old Sheet PIling

[beanbag]

I wish to analyze old Belval BV-4N steel sheet pile retaining wall, located in the US. Historic drawing identifies two types of steel for the sheet piling....44/52 steel and 50/60 steel. Can anyone tell me what these numbers represent? Thanks.

Thanks, cvg.

I found 44/52, 52/60 and 50/61 in the Frodingham catalog.

No 50/60 found so I suppose I should assume similar yield strength to 52/60 or 50/61?
