I-atmospheric corrosion resiting structural steel plate isetshenziswa kabanzi ukwakha iziqukathi zokuthutha kanye neziqukathi ezingasogwini, njenge-Sheduli yesiqukathi sokugcina udoti, Iziphephelo Zesimo Sezulu, Amabhokisi Amathuluzi, Iziqukathi Zokusebenzela nokunye.
Imininingwane:
Ubukhulu: 3mm-150mm
Ububanzi: 30mm-4000mm
Ubude: 1000mm--12000mm
Okujwayelekile: ASTM EN10025 JIS GB
Amandla aphezulu aqinile we-eathering steel plate Q415NH enamandla aqinile ngaphakathi kuka-520-680 Mpa, ukujiya okulinganayo, amandla esivuno kufanele abe ngaphezu kuka-415Mpa lapho ukuvuthela kungu-16mm. Ngokwezinga lokushisa elihlukile lomthelela, ipuleti lensimbi le-Q415NH lingaba yi-Q415NHA, Q415NHB, Q415NHC,
I-Q415NHD, Q415NHE。 I-Q415NHA idinga ukuhlolwa komthelela wezinga lokushisa okuphansi okungama-40 degrees Celsius, futhi i-Q415NHA ayidingi ukuhlolwa komthelela.
