E mālama i ka hoʻokomo ʻana i ka pā alanui hao zinc

ʻO nā pilikia palekana ka mea e hopohopo mau ai nā mea a pau. ʻOiai ʻaʻole hiki ke pale ʻia nā pōʻino i kekahi manawa, pono e pale iā lākou ma mua o ka hiki ʻana mai. No laila, pono ʻoe e hoʻokomonā pā kila zinci ka wā hana hale hou a i ʻole hana alanui. ʻO ka ʻoiaʻiʻo, ʻo ka hoʻokomo ʻana i nā pā alanui zinc steel ua loaʻa i ka hapa nui o ka hōʻemi ʻana i ka nui o nā ulia pōpilikia a me ka palekana o ka huakaʻi o nā kamaʻāina!

Ua kapa ʻia nā pā alanui he pā alanui. Nui nā ʻano o lākou. Ma muli o ko lākou paʻakikī, hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana: nā pā paʻa, nā pā semi-rigid a me nā pā paʻa. ʻO nā pā alanui zinc kila maʻamau e pili ana i kahi ʻano me ka hiki ke pale. ʻO ka pā kūpaʻa. He hale kēia i hoʻopaʻa ʻia ma luna o ke kia me nā kaula he nui me ka hoʻopili ʻana i ka ʻāʻī mua. Ke hilinaʻi nui nei i ke koʻikoʻi tensile o nā kaula e pale aku i ka hui ʻana o ke kaʻa a hoʻopaʻa i ka ikehu.

Ke hana nei ke kaula i loko o ka laulā elastic a ʻaʻole pono e hoʻololi. He nani ke ʻano o kēia ʻano pā, ʻaʻohe manaʻo hoʻokaumaha i ka wā e hoʻokele ai ke kaʻa, akā maikaʻi ʻole ka hopena induction line of sight. ʻO ka pā alanui zinc steel semi-rigid e pili ana i ka hoʻomau ʻana o ka pā kaola-kolume mau. He hale kaola kēia i hoʻopaʻa ʻia me nā pou, e hilinaʻi ana i ka deformation kulou a me ke ʻano o ka pā e pale aku i ka hui ʻana o ke kaʻa.

E like me nā ʻano hana like ʻole, hiki ke hoʻokaʻawale ʻia nā pa kaola i loko o ka W-shaped wave beam fences, tube beam fences, box girder fences, etc. Ua loaʻa iā lākou a pau ke ʻano o ka rigidity a me ka paʻakikī, e hoʻomoʻi i ka ikehu collision ma o ka deformation o ka lāʻau, maʻalahi ke hoʻololi i nā ʻāpana ʻino, loaʻa kahi laina o ka ʻike i ka hopena, a he nani ke ʻano. ʻO ka ʻoʻoleʻapā alanui hao zinc'ōlelo ma'amau i ka ho'olālā pā non-deformable.

He ʻano pā pōhaku sima kēia me kahi ʻano cross-sectional, e hilinaʻi ana i ka piʻi ʻana o ke kaʻa, deformation a me ka friction e komo i ka ikehu collision. ʻAʻole hoʻopōʻino ʻia nā pā ʻoʻoleʻa i ka wā o ka hui ʻana, a ʻaneʻane pōʻino ʻole. He haʻahaʻa loa ke kumukūʻai mālama, akā he manaʻo koʻikoʻi ma luna o ke kaʻa, a maʻalahi hoʻi e hōʻiliʻili i ka hau ke hoʻohana ʻia i nā wahi anuanu.
