kila Corten B
ʻO ka papa kila ʻo ASTM Corten B kahi huahana i ʻōwili ʻia o nā kila hoʻolālā i nā kūlana hoʻopuka ʻenehana me ka hoʻomaikaʻi ʻana i ka corrosion resistance o ka lewa.
ʻO Corten B - he kila kūpaʻa i ka wā i kūpono i nā hale kaumaha a me nā ukana.
Hoʻokumu ka mea i kona papa pale ponoʻī ke ʻike ʻia i nā mea lewa. ʻO ka mea nui, ʻino ka papa luna a laila pale i ke kila ma lalo. ʻAʻole pono ka hoʻopau kūlohelohe i kekahi ʻano o ka mālama ʻana e like me ke pena kiʻi, e hoʻolilo ai i ka mea i mea ʻoi aku ka maikaʻi o ke kumu kūʻai ma mua o nā kila kūkulu ʻē aʻe.
Pono ka pena a me ka mālama ʻana inā pulu mau ka hale no ka mea ʻaʻole e hana ʻia kahi papa pale. ʻO kahi laʻana maikaʻi ʻo ia kahi e hui ai ke kumu o ka hale me ka lepo a i ʻole i loko o kahi hapa.
