He ʻāpana koʻikoʻi a maʻalahi hoʻi ka uea kila prestressed i ka ʻoihana kūkulu hale. Hana ʻia mai nā koʻokoʻo uea kila kalapona kiʻekiʻe i ʻōwili wela ʻia i mālama ʻia i ka wela a hana anu ʻia, ua hoʻolālā kūikawā ʻia kēia mau uea e hoʻokō i nā koi koi o ka hoʻoikaika ʻana i ka sima prestressed. ʻO ka nui o ke kalapona o ka uea kila he 0.65% a i 0.85%, ʻo ka nui o ka sulfur a me ka phosphorus ma lalo o 0.035%, a he ikaika a he kūpaʻa maikaʻi loa.
Ua holomua nui ka uea kila prestressed mai kona hana ʻoihana a me ka hoʻohana ʻana i nā makahiki 1920. I kēia lā, ua hana ʻia nā ʻano huahana like ʻole i kūpono no nā noi like ʻole a me nā ʻano like ʻole. ʻO kēia mau mea me ka uea i huki anu ʻia, ka uea i hoʻopololei ʻia, ka uea hoʻomaha haʻahaʻa, ka uea galvanized a me ka uea i helu ʻia. ʻO kēia mau huahana, i hui pū ʻia me nā kaula kila prestressed, ua lilo i nā ʻano kila prestressed i hoʻohana nui ʻia ma ka honua.
No ke ʻano o ka hoʻokaʻawale ʻana, he koho kaulana ka uea PC serrated haʻahaʻa. ʻO kona ikaika tensile maikaʻi loa e kūpono ai no nā noi koʻikoʻi kiʻekiʻe. Eia kekahi, ʻo ka mānoanoa o ka uea kila he 2.64 mm, e kūpono ai no nā papahana kūkulu like ʻole. Eia kekahi, ua kūlike kēia uea sima prestressed me nā kūlana i kuhikuhi ʻia ma 1084 SAEJ403, e hōʻoiaʻiʻo ana i kona maikaʻi a me ka hilinaʻi.
ʻO kekahi o nā hiʻohiʻona kaulana loa o ka uea kila prestressed ʻo ia kona ikaika tensile kūikawā. Ma keʻano laulā, ʻoi aku ka ikaika tensile o kēia ʻano uea kila ma mua o 1470MPa, e neʻe mālie ana i ka pae ikaika nui o 1670 ~ 1860MPa. Eia kekahi, ua loli pū ke anawaena o ka uea i ka hala ʻana o ka manawa, mai 3 a 5 mm a i ka pae o kēia manawa o 5 a 7 mm. ʻO kēia ikaika i hoʻonui ʻia a me ke anawaena nui e hoʻolilo i ka uea prestressed i mea elastic loa a hiki ke kū i nā ukana nui.
Ma muli o kona mau waiwai maikaʻi loa, hoʻohana nui ʻia ka uea kila prestressed ma nā ʻano hana kūkulu like ʻole. Hoʻohana pinepine ʻia ia e hoʻoikaika i nā hale e like me nā alahaka, nā hale a me nā ala kaʻaahi e hoʻomaikaʻi i ko lākou hiki ke hāpai i ka ukana a me ke kūpaʻa o ke kūkulu ʻana. Hilinaʻi nui nā ʻoihana ʻoihana a me nā ʻoihana i ka uea kila prestressed e hōʻoia i ka lōʻihi a me ka palekana o kā lākou mau papahana.
I ka hōʻuluʻulu manaʻo, ua hoʻololi ka hoʻomohala ʻana o ke uea kila prestressed i ka ʻoihana kūkulu hale. ʻO ka hui pū ʻana o ke kila kalapona kiʻekiʻe a me nā ʻenehana mīkini holomua e hopena i nā huahana like ʻole e kūpono no nā ʻano hana like ʻole. Me kahi ākea o nā hoʻokaʻawale a me nā koho nui, a me ka ikaika tensile maikaʻi loa a me nā hoʻohana he nui, ʻo ke uea kila prestressed he mea nui ia i ke kūkulu ʻana o kēia wā.

Ma ke ʻano he alakaʻi ʻoihana ʻoihana metala Kina, ʻo ke kālepa kila aupuni a me ka logistics "Hunerd good faith enterprise", ʻo Kina kila kālepa ʻoihana, "Top 100 private enterprises in Shanghai". Lawe ʻo Shanghai Zhanzhi industry Group Co., Ltd.,(i hoʻopōkole ʻia i Zhanzhi Group) i ka "Integrity, Practicality, Innovation, Win-Win" ma ke ʻano he loina hana hoʻokahi, e hoʻomau mau ana i ka hoʻokō ʻana i ka noi o ka mea kūʻai aku ma kahi mua.
