Which steel grades does the EPD cover?

The certification letter states the scope in Chinese grades: Q195, Q235, Q275, Q355, Q420 and Q460 series. Those six are the grades named on the certificate, so they are the safe answer for a specification.

If your project is written to an EN, Japanese or American grade, the equivalent to look at would be S235JRH or S355J2H under EN 10219, SS400 or SS490 under JIS, or A500 and A501 under ASTM. These are not named in the letter, so we would rather confirm than let you assume: tell us the grade and the size, and we will say plainly whether it sits inside the certified scope.

Availability is a separate question from certification. A grade being producible does not mean every size is held in stock, so confirm both with our sales team before specifying. Grade-by-grade notes are on our EPD certification page.
