Ngokomgangatho wayo omncinci wesivuno, intsimbi yesakhiwo seplate yenqanawa, oko kukuthi, intsimbi yesakhiwo se-hull, yahlulwe kwiiklasi zamandla alandelayo: i-general-strength structural iron kunye ne-high-high-high-high-high-strey structure.Ipleyiti yomkhumbi ibhekisela kwisitya sentsimbi esishushu esiveliswe ngokuhambelana neemfuno zemithetho yolwakhiwo loluntu lokuhlelwa kokwenziwa kwezakhiwo zeenqanawa.Intsimbi yesakhiwo esinesiseko somgangatho we-China Classification Society ihlukaniswe ngamabakala amane omgangatho: A, B, D, kunye no-E (okt CCSA, CCSB, CCSD, CCSE);umgangatho ophezulu wokwakhiwa kwensimbi yomgangatho we-China Classification Society yimigangatho emithathu yamandla, amanqanaba amane omgangatho.

Zimbini: IiNgcaciso ezahlukeneyo
Intsimbi yesakhiwo se-hull yahlulwe ngamabakala anamandla ngokwenqanaba layo elincinci lesivuno: intsimbi yolwakhiwo lwamandla ngokubanzi kunye nentsimbi yolwakhiwo oluphezulu.
Umgangatho wentsimbi yesakhiwo somgangatho we-China Classification Society ihlukaniswe ngamabakala amane omgangatho: A, B, D, kunye no-E;umgangatho ophezulu wokwakhiwa kwentsimbi yomgangatho woMbutho woHlelo lwaseTshayina ngamabakala amathathu omelela kunye namabanga amane asemgangathweni:

A32 D32 E32 F32 ≤50mm Carbon elingana Ceq,% hayi ngaphezulu kwe 0.36>50-100 Carbon elingana Ceq,% hayi ngaphezulu kwe 0.4A36 D36 E36 F36 ≤50mm Carbon ilingana Ceq,% hayi ngaphezulu kwe 0.0-18 Cebon elingana 0. ,% hayi Ngaphezulu kwe 0.4A40 D40 E40 F40≤50mm Carbon elingana Ceq,% hayi ngaphezulu kwe 0.4>50-100 Carbon elingana Ceq,% Non-carbon elingana calculation formula C eq（%）=C+Mn/6 +(Cr +Mo+V)/ 5 +(Ni+Cu)/15...

3. Ukuqaliswa kweplate yenqanawa Intsimbi yamandla aqhelekileyo kwisakhiwo se-hull ihlukaniswe ngamabakala amane: A, B, D kunye no-E. Amandla okuvelisa (kungekho ngaphantsi kwe-235N / mm ^ 2) kunye namandla okuqina (400～520N / mm ^ 2) iyafana, kodwa amandla empembelelo kumaqondo obushushu ahlukeneyo ahlukile;high-amandla hull lwesakhiwo intsimbi yahlulwe ngokwamabakala amandla ngokwamandla ayo isivuno ubuncinane, kwaye ibakala amandla ngalinye yahlulwe ibe A, D, E ngokungqinelana nefuthe ukuqina., inqanaba F4.Amandla esivuno se-A32, i-D32, i-E32 kunye ne-F32 ayikho ngaphantsi kwe-315N / mm ^ 2, kwaye amandla e-tensile yi-440～570N / mm^2.-40 °, -60 ° ukuqina kwempembelelo;amandla esivuno se-A36, D36, E36, F36 ayikho ngaphantsi kwe-355N/mm^2, amandla okuqina yi-490～620N/mm^2, A, D, E kunye no-F amele ukuqina kwempembelelo enokuphunyezwa kwi-0°, -20 °, -40 °, kunye -60 ° ngokulandelelanayo;amandla esivuno se-A40, D40, E40, kunye ne-F40 ayikho ngaphantsi kwe-390N/mm^ 2. Amandla e-tensile yi-510～660N/mm^2, kunye no-A, D, E, kunye no-F bamele ukuqina kwempembelelo enokubakho. ifunyenwe ku-0 °, -20 °, -40 °, kunye -60 ° ngokulandelelanayo.
