Nā waiwai mechanical piha o ke kila kahawai

ʻEono mau pono a me nā ʻano o ke kila kahawai:

Hiki ke ʻōlelo ʻia he kiʻekiʻe ke kūʻai aku ʻana o ke kila kahawai ma waena o nā huahana kila āpau, ʻoiai ʻaʻole kūpono wale ke kila kahawai no ke kūkulu ʻana, akā no ke kūkulu ʻana i nā mea liʻiliʻi a me nā mea waena i ke ola o kēlā me kēia lā, me nā hana piha loa. ʻOiai ua wehewehe ʻo I-beam i nā pono ʻeono a me nā ʻano o I-beam me ʻoe.

1. Ke kumukūʻai lapaʻau haʻahaʻa: ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka galvanizing wela ma mua o nā uhi pena ʻē aʻe;

2. Paʻa: ʻo ke kila kihi galvanized wela-dip nā ʻano o ka ʻili like, ka papa zinc, ʻaʻohe plating nalowale, ʻaʻohe kulu, hoʻopili ikaika a me ke kūpaʻa ikaika i ka corrosion. I ke kaiapuni suburban, hiki ke mālama ʻia ka mānoanoa anti-rust galvanized wela-dip maʻamau no nā makahiki he 50 me ka ʻole o ka hoʻoponopono ʻana; I nā wahi kūlanakauhale a i ʻole ma waho, hiki ke mālama ʻia ka uhi antirust galvanized wela-dip maʻamau no 20 mau makahiki me ka ʻole o ka hoʻoponopono ʻana;

ʻEono mau pono a me nā ʻano o ka I-beam

3. Hilinaʻi maikaʻi: ua hui pū ʻia ka uhi zinc a me ke kila a lilo i ʻāpana o ka ʻili kila, no laila ua hilinaʻi nui ʻia ke kūpaʻa o ka uhi ʻana;

4. Ikaika ka paʻakikī o ka uhi ʻana: hana ka uhi galvanized i kahi ʻano metallurgical kūikawā, hiki ke kū i ka pōʻino mechanical i ka wā o ka lawe ʻana a me ka hoʻohana ʻana;

5. Palekana piha: hiki ke uhi ʻia kēlā me kēia ʻāpana o ka ʻāpana i uhi ʻia me ka zinc, a hiki ke pale piha ʻia ma ke kaumaha, ke kihi ʻoi a me kahi huna;

6. E mālama i ka manawa a me ka hoʻoikaika: ʻoi aku ka wikiwiki o ke kaʻina hana galvanizing ma mua o nā ʻano hana hana uhi ʻē aʻe, a hiki ke pale i ka manawa e pono ai no ka pena ʻana ma ke kahua ma hope o ke kau ʻana.
