The LEED-EBOM Reference Guide doesn’t explicitly offer the same default for steel recycled content that is afforded under LEED-NC. That said, the 25% default is a conservative estimate and isn’t unreasonable for products that fall under EBOM MRc3. It’s likely that the 25% default will pass the LEED review process, but it’s always ideal to provide manufacturer product data sheets that confirm the actual recycled content level.
