U-like nail kumukuai

Me ka wehe ʻana o ka metro ma nā kūlanakauhale nui a me ka nui, a me ka hoʻolaha ikaika ʻana o ka lawelawe subway i nā mea hana pūnaewele, ʻo ka poʻe i maʻa i ka subway e like me ke ʻano o ka lawe ʻana i kēlā me kēia lā a me ke kaʻa o ke kūlanakauhale.Ke hilinaʻi nei kēia poʻe kamaʻāina, makemake i ka subway a hauʻoli i kona wikiwiki, makemake pinepine lākou e kapa iā lākou iho ʻo ke kumukūʻai U-pin.Hoʻohana nui ʻia i ka ʻoihana, mahiʻai, mahiʻai, kūkulu ʻana, kaʻa a me nā mea ʻē aʻe i hoʻohana ʻia i loko o ke kula o ke kiʻekiʻe kiʻekiʻe haʻahaʻa haʻahaʻa carbon uea laina o ka kuʻi ʻana a lilo, a laila ma hope o ke anuanu, wela wela plating, PVC plastic coated surface passivation, penei e like me ka plasticizing kaʻina hana, ka hana ʻana o ka metala me ka ʻili maʻemaʻe, ka lole ʻaʻahu, paʻa ka hui solder, kūpaʻa, kūpaʻa kūʻē, nā ʻano kūʻē corrosion maikaʻi.

U kuihana ʻia ke kumu kūʻai o ke kiʻekiʻe kiʻekiʻe o ke kila kila wili lālani;No ka laʻana, ka uhi pale mīkini, ka pā holoholona, ​​ka pā pua, ka pā kiaʻi puka makani, ka pā kanal, ka hale moa a me ka hale keʻena meaʻai hīnaʻi, ka hīnaʻi pepa a me nā mea hoʻonaninani, ʻoi aku ka waika, alkali, paʻa wili, nani a me nā ʻano ʻē aʻe.
U kui kumu koho o ka uea hao uwea, wela dip galvanized uea a me ka eleele hao uea a me ka 'ē aʻe kiʻekiʻe-koʻikoʻi uea, welded, PVC a PE, PP pauka ma hope o curing uhi kona ili, me ka ikaika adhesion, maikaʻi corrosion kū'ē, alohilohi kala a me pela aku.
