ʻO ka mea mua, ma ka European standard DX51D, D kū no ka 'plated', 'o ia hoʻi,ʻo ka pā kila ma luna o kaʻili he papa kila.X 'o ia ho'i 'zinc'.Ma waena o lākou, hōʻike ʻo 51D i ke kumu.Hōʻike ʻo 51D i ke kila hana maʻamau.A i ʻole 52D ma ka papa, ʻo ia hoʻi, he papa hōʻailona ka papa.Inā he 53D, hoʻohana ʻia ka ʻili no ke kaha kiʻi hohonu.Ke piʻi nei ka helu X ma 5XD, ʻo ia ka mea ʻoi aku ka maikaʻi o ka rigidity, ʻoi aku ka ikaika o ka palupalu paʻa.Hoʻohana maʻamau ʻia ka maʻamau ʻEulopa e nā wili kila o ka mokuʻāina mua, e like me Anshan Iron and Steel, Benxi Iron and Steel, Wuhan Iron and Steel, etc. +Z/AZ DX54D+Z/AZ.
ʻO ka lua ka American Standard ASTM A792.No ka maʻamau ʻAmelika, ʻaʻole liʻiliʻi ka pilina me nā poʻe, no laila ʻaʻole hiki iaʻu ke haʻi i nā huaʻōlelo no kēia manawa.E kala mai iaʻu.Eia nō naʻe, ʻike ʻia ua ʻae ʻia ka American Standard e kekahi mau ʻoihana hui kūloko.E like me: Yehui China, South Korea a me nā hale wili kila ʻē aʻe.ʻO nā kauoha kālepa haole o nā ʻoihana hui nui nā ʻoihana kūloko a me nā ʻoihana kūloko, no laila i mea e hoʻokō ai i ke kālepa kūʻai aku, he mea maʻamau ke ʻae ʻana i ke kūlana ʻAmelika.
ʻO ke kolu o ke ʻano, ka SGCC maʻamau Kepanī, eia kahi hoʻolauna kūikawā i nā leka a me nā helu o ka waihona zinc layer ma hope o ke kūlana Iapana, e like me ka maʻamau maʻamau o kēlā me kēia lā SGCC+Z.E hoʻohui ʻia ka hōʻailona paona papa Zinc ma hope o Z, e like me SGCC+Z27.No laila, manaʻo kekahi poʻe ʻo + Z27 ke ʻano o ka zinc content he 27 grams no ka mika square?ʻaʻole.ʻO Z27 a me Z270 ma ka European standard ma luna o ka manaʻo like, ʻo ia hoʻi, ke ʻano o ka galvanized 270 grams.
ʻO ka hā o nā ʻano ʻoihana.ʻO ka maʻamau ʻoihana kahi papa kila i hoʻomohala ʻia e kekahi mau hale wili kila nui e like me nā kūlana honua e like me ka standard European, American standard a me Japanese standard.E like me Baosteel's Q/BQB 440-2009 TDC51D+Z/AZ maʻamau.Ke kū ʻana o Baosteel Enterprise
