I-S355 ne-Q355 zombili ziyizimpawu zensimbi yesakhiwo, kodwa zivela kumazinga ahlukene futhi anomehluko othile ekucacisweni kwazo nasekusetshenzisweni kwazo.
Insimbi ye-S355
Okujwayelekile: EN 10025-2 (European Standard)
Ibanga: S355
Incazelo: I-S355 iyinsimbi yesakhiwo esinamandla amakhulu, enengxubevange ephansi enamandla okukhiqiza okungenani angama-355 MPa. Ivamise ukusetshenziswa ekwakhiweni nasekusetshenzisweni kwesakhiwo ngenxa ye-weldability yayo enhle kanye nokusebenziseka kwayo.
Ukwehliswa Okujwayelekile:
I-S355JR: Insimbi yesakhiwo esivamile esinamandla amancane esivuno angu-355 MPa namandla omthelela angu-27J ekamelweni lokushisa.
I-S355J0: Amandla omthelela amancane angu-27J ku-0°C.
I-S355J2: Amandla omthelela amancane angu-27J ku- -20°C.
Q355 Insimbi
Okujwayelekile: GB/T 1591 (Izinga lesiShayina)
Ibanga: Q355
Incazelo: I-Q355 iyinsimbi yesakhiwo esiphezulu esinamandla amancane okukhiqiza angu-355 MPa, afana ne-S355. I-"Q" imele "Qu" (iphuzu lesivuno), futhi "355" ibhekisela emandleni amancane okukhiqiza ku-MPa.
Ukwehliswa Okujwayelekile:
I-Q355B: Amandla omthelela amancane angu-27J ku-20°C.
Q355C: Amandla omthelela amancane angu-27J ku-0°C.
I-Q355D: Amandla omthelela amancane angu-27J ku- -20°C.
Isicelo:

Ipayipi lesakhiwo
Ipayipi lensimbi yokubiyela
Izingxenye zokufakwa kwe-solar
Ipayipi lesandla
Ukulawula Ikhwalithi Eqinile:
1) Ngesikhathi nangemva kokukhiqiza, izinduku ezi-4 ze-QC ezinesipiliyoni seminyaka engaphezu kwemi-5 zihlola imikhiqizo ngokungahleliwe.
2) Ilabhorethri kazwelonke egunyaziwe enezitifiketi ze-CNAS
3) Ukuhlolwa okwamukelekayo okuvela enkampanini yangaphandle eqokwe/ekhokhelwa umthengi, njenge-SGS, BV.
4) Igunyazwe yiMalaysia, Indonesia, Singapore, Philippines, Australia, Peru kanye ne-UK. Siphethe i-UL/FM, ISO9001/18001, izitifiketi ze-FPC
Ukupakisha Nokulethwa:
Imininingwane Yokupakisha : kuzinyanda ezinama-hexagonal ezifanele ulwandle ezipakishwe ngemicu yensimbi, Nezihlilingi ezimbili zenayiloni zenqwaba ngayinye.
Imininingwane Yokulethwa : Kuye nge-QTY, ngokuvamile inyanga eyodwa.
Mayelana NATHI:
