U-girazi rudzi rutsva rwekuvaka chimiro chegirazi, uye yakangoshandiswa kwemakore makumi mana kunze kwenyika.Kugadzirwa uye kushandiswa kweU-girazi muChina kwakasimudzirwa zvishoma nezvishoma mumakore achangopfuura.U-girazi inogadzirwa nekutsikirira nekuwedzera isati yaumba, uye chikamu chemuchinjikwa chiri muchimiro che "U", saka chinotumidzwa U-girazi.

U-mhando yegirazi classification:

1. Maererano nemhando yemavara: isina ruvara uye ine mavara maererano.Girazi rine ruvara rweU-shaped rinopfapfaidzwa uye rakaputirwa.
2. Maererano nechikamu chegirasi pamusoro: yakatsetseka uye isina muenzaniso.
3. Zvinoenderana neiyo girazi simba kupatsanura: yakajairika mhando, yakaomeswa, firimu, insulation layer, inosimbisa firimu, nezvimwe.

Kuiswa zvinodiwa zvekuvaka U-shaped glass

1. Fixed profiles: aluminium profiles kana mamwe maprofayiri esimbi achagadziriswa pachivako nesimbi isina tsvina mabhoti kana rivets, uye furemu zvinhu zvichange zvakasimbiswa zvakasimba nemadziro kana kuvhura kwechivako, pasina asingasviki 2 akagadzika mapoinzi pamamita mutsara.

2. Girazi muchidimbu: kuchenesa mukati megirazi rakafanana neU, riise mumapuranga, cheka chikamu chepurasitiki chinoputika muhurefu hunoenderana uye uiise mumapuranga akaiswa.

3. Kana girazi rakagadzirwa neU rakaiswa kune zvikamu zvitatu zvekupedzisira, tanga kuisa zvidimbu zviviri zvegirazi mufuremu, wozoisa chisimbiso nechidimbu chechitatu chegirazi;Kana iyo yakasara yakafara yegomba isingakwanise kuiswa mugirazi rose, iyo U-yakaita girazi inogona kuchekwa nenzira yekureba kuti isangane nehupamhi hwasara, uye girazi rakachekwa rinofanira kuiswa kutanga.

4. Mukana uri pakati pemagirazi eU-unofanirwa kugadziriswa maererano nekupisa kana kusiyana kwekushisa kunowedzera;

5. Kana hupamhi hwakachinjika hwegirazi rakaumbwa neU rapfuura 2m, kutsauka kwakatwasuka kwenhengo inochinjika kunogona kuita 3mm;Kana kureba kusingapfuuri 5m, iyo perpendicularity kutsauka kwechimiro inobvumirwa kuva 5mm;Kana kureba kusingapfuuri 6m, kutsauka kwepapa kwenhengo kunobvumirwa kuva 8mm;

6. Mukaha pakati pechigadziro uye girazi rakafanana neU richazadzwa nepedhi elastic, uye nzvimbo yekubatana pakati pepedhi negirazi uye chimiro haifaniri kudarika 12mm;
