Nangona iChina yenza impumelelo enkulu kwizakhiwo zentsimbi kwiintsuku zokuqala, yahlala kwinqanaba lezakhiwo zentsimbi ixesha elide.Kwada kwaba sekupheleni kwenkulungwane ye-19 apho ilizwe lam laqalisa ukusebenzisa izakhiwo zentsimbi zale mihla.Emva kokusekwa kweNew China, ukusetyenziswa kwezakhiwo zensimbi kuye kwaphuhliswa kakhulu, kudlula kakhulu kwixesha elidlulileyo ngokubhekiselele kubuninzi kunye nomgangatho.Umgangatho wesakhiwo sentsimbi esikhanyayo sihlanganiswe nesakhelo sentsimbi esithambileyo esine-cold-formed okanye i-composite beam, ipleyiti yesakhiwo ye-OSB yomgangatho, izixhaso, izihlanganisi, njl. Izinto ezisetyenzisiweyo ziyibhodi ye-strand e-oriented, i-sement fiberboard, kunye ne-plywood.Le migangatho ikhaphukhaphu inokumelana nemithwalo ye-316 ukuya kwi-365 yeekhilogram kwi-square meter nganye.

Inani lezakhiwo zentsimbi libonisa amandla ezoqoqosho kunye neqondo lophuhliso loqoqosho lwelizwe okanye ummandla.Emva kokungena kowama-2000, uqoqosho lwelizwe lam luye lwakhula kakhulu, amandla alo esizwe aye aphuculwa kakhulu, kwaye imveliso yawo yentsimbi iye yaba ligunya lehlabathi.Ekwakhiweni, kucetywayo ukuba "isetyenziswe ngokusebenzayo nangokufanelekileyo insimbi".Ulwakhiwo luyanda ngokuthe ngcembe kwiindawo eziphuhliswe ngokwezoqoqosho.Ngokukodwa malunga ne-2008, phantsi kwempembelelo yeMidlalo yeOlimpiki, kwakukho i-boom kwizakhiwo zesakhiwo sensimbi, kwaye imfuno eqinile yemarike yakhuthaza ukuphuhliswa ngokukhawuleza kwezakhiwo zesakhiwo sensimbi.Inani elikhulu leendawo zesakhiwo sentsimbi, izikhululo zeenqwelo moya, izikhululo kunye nezakhiwo eziphakamileyo zakhiwe.Phakathi kwazo, ezinye izakhiwo zeSteel zikumgangatho wehlabathi kwitekhnoloji yemveliso kunye nokufakwa, njengamabala emidlalo yeOlimpiki kunye nezinye izakhiwo.

Emva kweMidlalo yeOlimpiki, izakhiwo zentsimbi ziye zaziwa kwaye zaphuhliswa ngokuqhubekayo.Izakhiwo zentsimbi zisetyenziswa ngokubanzi kwizakhiwo, koololiwe, iibhulorho kunye nezindlu.Kukho amashumi amawaka amashishini esakhiwo sentsimbi enobungakanani obahlukeneyo.Isixhobo sokulungiswa kwesakhiwo sentsimbi yehlabathi sigqityiwe ngokusisiseko, njengeentloko ezininzi ezinobubanzi.Umatshini wokugaya, umbhobho wentsimbi we-multi-dimensional intersecting line cutting machine, i-corrugated plate automatic welding machine tool, njl. njl amashishini.Kwiminyaka yakutshanje, imveliso yensimbi yonyaka ifikelele kwiitoni ezingaphezu kwezigidi ezingama-600, kwaye iintlobo zetsimbi zinokuhlangabezana ngokupheleleyo neemfuno zokwakha.Inkcazo yoyilo lwesakhiwo sensimbi, imigangatho yempahla yesakhiwo sentsimbi, ubunjineli bentsimbi yobunjineli bomgangatho wokwamkelwa komgangatho, kunye neenkcukacha ezahlukeneyo kunye neendlela zokwakha ishishini ziphelele.
