ʻO SPHT1 ka pepa i ʻōwili wela, ʻo ia hoʻi ka ʻili kila ʻōwili wela a me ke kāʻei. E pili ana i nā papa kila me ka laulā nui a i ʻole like me 600mm a me ka mānoanoa o 0.35-200mm a me nā ʻāpana kila me ka mānoanoa o 1.2-25mm.

ʻO ke kūkulu ʻia ʻana o ka hot rolled coil he mea metala i hoʻohana nui ʻia i ka hana a me nā ʻoihana mīkini.

ʻO S355JR ke kila hoʻolālā wela ʻEulopa, ʻo S355JR ke kūlana hoʻokō ʻo EN10025.

ʻO MS ke kū nei no ka "mea kila ʻoluʻolu," e pili ana i ka ʻike kalapona haʻahaʻa o ka mea. ʻO kekahi o nā ʻāpana kila i ʻōwili ʻia he pā kila māmā me ka helu pā SS400.

ʻO ka pā kila wela wela he mea metala maʻamau, i hoʻohana nui ʻia i ke kūkulu ʻana, nā moku, nā alahaka, nā kaʻa, nā pipeline, nā mīkini hana a me nā ʻano ʻē aʻe ma muli o kona ʻano kino maikaʻi a me nā ʻano mechanical.

ʻO ka pepa kila ʻōwili wela he pā metala i hana ʻia ma ka hoʻomehana ʻana i ka billet kila i kahi mahana ma o ke kaʻina ʻōwili wela a laila ʻolokaʻa a hana ʻia. He kiʻekiʻe ka ikaika a me ka pale ʻana i ka corrosion a hoʻohana nui ʻia i ka hana ʻana, ka hana ʻana, ka hana kaʻa a me nā māla ʻē aʻe. Hāʻawi mākou i nā pale kila i'ōwili wela i nā kiko'ī likeʻole.
