ASTM B370 Roofing Sheet / Plate

Commonly referred to as roofing copper, this sheet is certified to the ASTM B 370 specification and is 99% pure copper. Different manufacturers may give different alloy numbers as part of their efforts to brand their product, but don’t let that confuse you. It's this stuff, and it's available in standard or custom cut lengths.

Refer to our "Guide to Copper" for grades, shapes and various properties.
