Is TG PRO ISO 9001 certified?

Yes, since 2018 (Bureau Veritas), in addition to PED certification since 2008. We forward the certificates on simple request — see the Quality and certifications page.

Is the seamless capacity up to 24" listed on TG PRO's website?

Not as of today: this capacity comes from a recent line the mill has not yet published on its site. We know it through our direct relationship with the mill.

Which grades does TG PRO produce?

304/L and 316/L in regular production, as well as 310, 321 and 316Ti. The mill's own website only lists 304, 304L and 316L, unchanged since its 1973 founding; the actual range is wider, known through SPS's direct relationship with the mill.

Is TG PRO certified for food-grade applications?

Yes: certified 3A and TISI (Thai standard), in addition to ISO 9001 and PED.
