Nā kumu koʻikoʻi e pili ana i ka hana kila o ka lā galvanized square steel pipes:

Nā paipu huinahā a me nā ʻāpana huinahā i hoʻopili ʻia me ka galvanized perforatedua hoʻolālā kūikawā ʻia no ka ʻāpana photovoltaic (PV), me nā pono koʻikoʻi o ke kākoʻo kūkulu ikaika kiʻekiʻe a me ke kūpaʻa lōʻihi i ka pala. Ma ka hoʻohana ʻana i kahi kaʻina hana galvanizing wela, hiki i ka mānoanoa o ka papa zinc i 70μm (e like me nā kūlana ISO 1461). Ua hala i ka hoʻāʻo pīpī paʻakai maʻamau ASTM B117 no 1000 mau hola, e hōʻoiaʻiʻo ana i ka hana paʻa no nā makahiki he 25 ma mua o nā wahi corrosive C5-level, e like me nā wahi kahakai me ka pīpī paʻakai kiʻekiʻe a me ka haumia ʻoihana.

ʻO ka hoʻolālā ʻāpana ʻāpana huinahā/ʻehā, i hui pū ʻia me ka ʻenehana perforation like, hāʻawi i nā waiwai mechanical kūlou a me ka torsional maikaʻi loa me ka hoʻomaʻamaʻa ʻana i ke kaula uwea a me ke kau ʻana modular, e hōʻemi nui ana i nā kumukūʻai kūkulu. Ke hoʻohālikelike ʻia me nā hoʻonā kila kihi kuʻuna a i ʻole nā mea hoʻohuihui alumini, ua hoʻemi ʻia ke kumukūʻai ola holoʻokoʻa ma mua o 30%. Eia kekahi, kākoʻo ia i nā ana i hana ʻia a me ka galvanization i hoʻonui ʻia, e kūpono ana no nā wahi koʻikoʻi e like me nā wao nahele, nā wahi kiʻekiʻe, a me nā kūlana wela humid.
