I-S355 kanye ne-Q355 zombili ziyizimpawu zensimbi yokwakha, kodwa zivela ezindinganisweni ezahlukene futhi zinomehluko othile ekucacisweni nasekusetshenzisweni kwazo.
Insimbi ye-S355
Okujwayelekile: EN 10025-2 (European Standard)
Ibanga: S355
Incazelo: I-S355 iyinsimbi yokwakha enamandla aphezulu, engenangxube eningi enamandla amancane okukhiqiza angu-355 MPa. Ivame ukusetshenziswa ekwakheni nasekusetshenzisweni kwesakhiwo ngenxa yokushibilika kwayo okuhle kanye nokusebenza kwayo kahle.
Ama-Subgrade ajwayelekile:
I-S355JR: Insimbi evamile yokwakha enamandla amancane okukhiqiza angu-355 MPa kanye namandla okushaya angu-27J ekushiseni kwegumbi.
S355J0: Amandla amancane omthelela angu-27J ku-0°C.
S355J2: Amandla amancane omthelela angu-27J ku--20°C.
Insimbi ye-Q355
Okujwayelekile: GB/T 1591 (Okujwayelekile kwesiShayina)
Ibanga: Q355
Incazelo: I-Q355 iyinsimbi yesakhiwo enamandla aphezulu enamandla okukhiqiza okungenani angu-355 MPa, afana ne-S355. Igama elithi "Q" limele "Qu" (iphuzu lokukhiqiza), kanti elithi "355" libhekisela emandleni okukhiqiza okungenani ku-MPa.
Ama-Subgrade ajwayelekile:
Q355B: Amandla amancane omthelela angu-27J ku-20°C.
Q355C: Amandla amancane omthelela angu-27J ku-0°C.
Q355D: Amandla amancane omthelela angu-27J ku--20°C.

Ukulawulwa Kwekhwalithi Okuqinile:
1) Ngesikhathi sokukhiqiza nangemva kokukhiqiza, abasebenzi abangu-4 be-QC abanolwazi olungaphezu kweminyaka emi-5 bahlola imikhiqizo ngokungahleliwe.
2) Ilabhorethri egunyaziwe kazwelonke enezitifiketi ze-CNAS
3) Ukuhlolwa okwamukelekayo okuvela kumuntu wesithathu oqokiwe/okhokhelwe ngumthengi, njenge-SGS, i-BV.
4) Kuvunywe yiMalaysia, i-Indonesia, iSingapore, iPhilippines, i-Australia, iPeru kanye ne-UK. Sinezitifiketi ze-UL /FM, ISO9001/18001, kanye ne-FPC
Ukupakisha Nokulethwa:
Imininingwane Yokupakisha: ezinqwabeni ezilungele ulwandle ezigoqwe ngemicu yensimbi, Nezihlikihli ezimbili ze-nylon zenqwabeni ngayinye.
Imininingwane Yokulethwa: Kuye nge-QTY, ngokuvamile inyanga eyodwa.
