Chitoliro cha square ndi dzina lachitoliro cha sikweyandichitoliro chamakona anayi, ndiko kuti, mapaipi achitsulo okhala ndi kutalika kofanana komanso kosagwirizana m'mbali. Amakulungidwa kuchokera ku chitsulo chokulungidwa pambuyo pokonza. Kawirikawiri, chitsulo chokulungidwa chimapatulidwa, kulinganizidwa, kupindika, kulumikizidwa kuti chipange chitoliro chozungulira, kukulungidwa mu chitoliro cha sikweya, kenako nkudulidwa kutalika kofunikira.
Ndi kupititsa patsogolo kosalekeza kwa kusintha kwa kapangidwe ka zinthu kumbali yopereka, makampani opanga machubu ang'onoang'ono ndi ang'onoang'ono awonetsa njira yabwino kwambiri. Malinga ndi detayi, patatha zaka pafupifupi khumi akutukuka, makampani opanga machubu ang'onoang'ono ku China akhala akukonzedwa bwino komanso kukonzedwa bwino mu kapangidwe ka zinthu, mulingo wabwino, zida zaukadaulo ndi zina, ndipo akhala dziko lopanga machubu ang'onoang'ono padziko lonse lapansi, ndipo akupita ku dziko lamphamvu kwambiri padziko lonse lapansi.chubu chamakona anayimafakitale.
Opanga zitsulo zopangira zitsulo m'makampani opanga mapaipi akuluakulu ndi amakona anayi, ndipo amagwiritsidwa ntchito kwambiri popanga makina, zomangamanga, zitsulo, magalimoto a ulimi, malo obiriwira a ulimi, makampani opanga magalimoto, njanji, zotchingira misewu yayikulu, mafelemu a ziwiya, mipando, zokongoletsera ndi zomangamanga zachitsulo m'makampani otsika. Tsopano imagwiritsidwa ntchito kwambiri popanga malo akuluakulu, monga mabwalo a ndege, mabwalo amasewera, masiteshoni, ndi zina zotero, zomwe zimagwiritsidwa ntchito ngati mafelemu akuluakulu achitsulo, makoma, ndi zina zotero, komanso kumanga nyumba zogona zachitsulo; Kuphatikiza apo, imagwiritsidwa ntchito ngati maziko ndi chithandizo cha zida mumakampani opanga makina, galimotoyo imagwiritsidwa ntchito ngati kukonzanso ma girders ndi magalimoto akuluakulu, thupi la njinga zamoto zamagalimoto atatu, ndipo imagwiritsidwa ntchito kulumikiza mafelemu osiyanasiyana pazinthu zapakhomo. Zinthu zopangira mapaipi okhala ndi ma frequency ambiri zimagwiritsidwa ntchito kwambiri mumakampani omanga mapaipi okhala ndi ma frequency ambiri okhala ndi ma frequency ambiri okhala ndi ma circular ndi ma circular ndi chitsulo chozizira cha nyumba, zomwe mapaipi okhala ndi ma square ndi rectangular ndi oposa 50%. Poganizira za kapangidwe ka nyumba ndi chuma, kuphatikiza mapaipi ozungulira ndi amakona anayi ndiko kuphatikiza kwabwino kwambiri kwa makampani omanga, komwe kungathandize kuti mafakitale a mafakitale ndi nyumba za anthu wamba zitukuke.
Mu chaka chatsopano, kupezeka ndi kufunikira kwa machubu a rectangular ku China kudzayamba kusintha m'malo mochepa. Izi zili choncho chifukwa, poganizira za kufunikira kwakukulu, chilengedwe chakunja cha chuma cha China chidzakhala chovuta kwambiri mu 2019, zomwe zidzawonjezera kutsika kwa chuma cha China. Pachifukwa ichi, dipatimenti yopanga zisankho iyenera kulimbikitsa kusintha kotsutsana ndi kayendetsedwe ka ndalama, kuphatikizapo mfundo zandalama zosalowerera ndale komanso zotayirira, mfundo zachuma zogwira ntchito kwambiri, makamaka kukhazikitsa ndalama zoyendetsera zomangamanga, ndikusunga ndalama zogulitsa nyumba pamlingo wapamwamba, kuti chuma cha China chikhalebe pamlingo woyenera, Izi zikuyenera kulimbikitsa kukula kosalekeza kwa kufunikira konse kwa machubu a rectangular ku China.
Kuchokera kumbali yopereka, pambuyo pa zaka zingapo zolimbikira mosalekeza, China yachita bwino kwambiri pakuchepetsa mphamvu zopangira chitsulo ndi zitsulo komanso kuchotsa "chitsulo chopondapo". Mphamvu zopangira chitsulo ndi zitsulo zachepa ndi matani mamiliyoni ambiri. Chifukwa chake, pankhani ya logic, chifukwa cha kuchepa kwa mphamvu zopangira chitsulo, kukula kosalekeza komanso kwamphamvu kwa mphamvu zopangira chitsulo kudzakhala kovuta kupitiliza.
Si zokhazo, patatha zaka ziwiri zotsatizana za kukula kwamphamvu kwa chitsulo (chitsulo chosaphwanyika ndi chitsulo, chomwe chili pansipa) mu 2017 ndi 2018, komanso chifukwa cha zomwe zachitika chifukwa cha kuchepetsa mphamvu ya chitsulo kwa matani mamiliyoni ambiri, kuchuluka kwa mphamvu ya chitsulo ku China kuyenera kuti kunakwera kwambiri, ndipo malo oti zinthu ziwonjezeke achepa kwambiri.
