P355N kila

ʻO P335N ka ipu hao paʻi i loaʻa ka palena haʻahaʻa loa ma 355 Mpa no ka mānoanoa ma lalo o 16mm. Hiki i ke kila Gnee ke hāʻawi i ka mānoanoa pā kila P355N ma waena o 6mm-300mm no ka hōʻoiaʻiʻo ʻana i ka waiwai kila i ka haku mele a me ka waiwai mechanical. No ka manawa hāʻawi o 1000 tons e kauoha i nā papa kila p355n, ʻo kā mākou manawa ʻōwili maʻamau i loko o 30 mau lā.
