Hoʻopaʻa ʻia ʻo Hot Dip Galvanized Channel Steel

(1) Loaʻa iā ia kahi papa zinc maʻemaʻe mānoanoa a paʻa e uhi ana i ka ʻili o ke kila, hiki ke pale i ka hoʻopili ʻana o ka substrate kila me kekahi hopena corrosive a pale i ka substrate kila mai ka corrosion.I ka lewa maʻamau, ua hoʻokumu ʻia kahi papa zinc oxide lahilahi a paʻakikī ma ka ʻili o ka papa zinc, he paʻakikī ke hoʻoheheʻe ʻia i ka wai, no laila he hopena pale i ka substrate kila.Inā hana ʻia ka zinc oxide a me nā mea ʻē aʻe o ka lewa i nā paʻakai zinc insoluble, ʻoi aku ka maikaʻi o ka hopena pale corrosion.

(2) Me ka iron-zinc alloy layer, i hui pū ʻia me ka compactness, hōʻike ia i ke kū kūʻokoʻa o ka corrosion kūʻokoʻa i ka lewa paʻakai paʻakai moana a me ka lewa ʻoihana;

(3) Ma muli o ka hoʻopaʻa paʻa ʻana, hiki ke hoʻoheheʻe ʻia ka zinc-hao, a he ikaika ke kūpaʻa aahu;

(4) No ka maikaʻi o ka ductility o ka zinc, a pili paʻa kona papa i ke kumu kila, hiki ke hoʻokumu ʻia nā ʻāpana wela i ke kuʻi anuanu, ka ʻōwili ʻana, ke kaha kiʻi uea, a me ke kulou ʻana me ka ʻole o ka hōʻino ʻana i ka uhi;
