Mwachibadwa pali mitundu yambiri ya awnings.M'zaka zaposachedwapa, ndi kutchuka kwa zomangamanga zitsulo, ntchito zitsulo kapangidwe awnings pang'onopang'ono kuwonjezeka.Chifukwa chomwe ma awnings achitsulo amatha m'malo mwa mitundu ina yazinthu ndikukhala msika pang'onopang'ono ndi mwachilengedwe chifukwa cha zabwino zake:

1. Kupanga kwamakina, m'malo mwa njira yowotcherera yachikhalidwe, kumatengera njira ya msonkhano.

2. Kugwira ntchito mwamphamvu, kuphatikiza ntchito zambiri, kupulumutsa mphamvu ndi kuteteza chilengedwe.

3. Zosavuta mawonekedwe, zapamwamba komanso zokongola.

4. Pogwiritsa ntchito luso lamakono lopopera, mtunduwo ndi wolemera, sumatha, wosakhwima komanso wachilengedwe.

5. Chokhazikika komanso chosasamalira chaka chonse.Chitsulo chachitsulo chimakhala ndi mawonekedwe ofanana, pafupi ndi thupi la isotropic homogeneous.Ntchito yeniyeni yogwirira ntchito yachitsulo ikugwirizana ndi zotsatira zowerengera zowerengera zomwe zimagwiritsidwa ntchito panopa, ndipo kudalirika kuli kwakukulu.

6. Mphamvu yapamwamba ndi kulemera kochepa.Chitsulo chimakhala ndi mphamvu zambiri komanso zotanuka modulus, kotero mamembala achitsulo ndi ochepa komanso opepuka.Pansi pa zovuta zomwezo, kulemera kwachitsulo kwachitsulo kumakhala kochepa, kotero kuti mapangidwe akuluakulu amatha kupangidwa.Chifukwa cha zigawo zing'onozing'ono, zimakhalanso zosavuta kukhazikitsa ndi kuyendetsa.

7. Mapulasitiki abwino komanso olimba.Kapangidwe kachitsulo kamakhala ndi pulasitiki wabwino komanso kulimba, ndi koyenera kunyamula mphamvu ndi katundu wosunthika, ndipo imakhala ndi magwiridwe antchito abwino a zivomezi.

8. Ili ndi weldability.Weldability amatanthauza kuthekera kwa chitsulo kusunga umphumphu wa weldment popanda kusweka panthawi ndi pambuyo kuwotcherera.Ndi chitukuko cha luso kuwotcherera ndi kutengera nyumba welded, kugwirizana kwa zitsulo nyumba kwambiri chosavuta.

9.Kuthandizira kupanga makina.Kapangidwe kachitsulo kamakhala ndi mbiri yomangirira ndi mbale zachitsulo mufakitale, yomwe ndi yabwino kupanga makina, kuchita bwino kwambiri, kuthamanga kwachangu, kulondola kwambiri kwazinthu zomalizidwa, komanso kutsimikizika kwamtundu kosavuta.
