Pasinei nekufanana kwazvo, maitiro ekugadzira, hunhu hwemakanika, uye mashandisirwo emhando mbiri idzi zvinopesvedzera zvakananga kuchengetedzeka uye hupfumi hwepurojekiti chero ipi zvayo. Heino kuenzanisa kwetekinoroji huru iyo chikamu chekuvaka chinofanira kuve nyanzvi muna 2026.
1. Maitiro Ekugadzira: Yakatonhora kana Yakaputirwa neHot
Uyu ndiwo musiyano mukuru pakati pemaprofile maviri aya:
- C Purlin: Yakagadzirwa uchishandisa simbi dzakarukwa dzemhando yepamusoro nenzira inotonhorera. Inowanzova nemadziro matete (1.6mm kusvika 3.2mm) uye ine "miromo" yekusimbisa kusimba kwechimiro ichiramba yakareruka.

2. Kugona Kutakura Mutoro uye Kushanda Kwenguva Refu
Munguva yekugadzirwa kwezvivakwa zvedhijitari muna 2026, kuverenga kunorema kwave kwakanyatsojeka:
- C Purlin: Yakagadzirirwa zvinhu zvinotakura zvinhu zvakawanda. Yakanakira kutamisa kumanikidzwa kwedenga nemadziro kuenda kusimbi huru. Zvisinei, kana zvinhu zvakawanda zvichitakura zvinhu, kuomarara kwayo kunenge kwakaderera.
- C Channel: Inopa kugona kukuru kwekutakura zvinhu kwenguva refu uye kuomarara kwe flexural. Inowanzo shandiswa sedanda kana koramu yezvidimbu zvipfupi kusvika pakati, inokwanisa kutakura zvinhu zvakakura zvinokwevera pasi pasina kusungwa kwenzvimbo.
3. Mepu yeChikumbiro Chekuvaka cha2026
| Mamiriro Ekushandisa | Chigadzirwa Chinokurudzirwa | Chikonzero |
|---|---|---|
| Matura Makuru Ekutakura Zvinhu | C Purlin | Dhizaini yakareruka inoderedza kushandiswa kwesimbi yese; jira rakarukwa rinopa dziviriro kwemakore anopfuura makumi maviri. |
| Zvitsigiro zveUriri zveNharembozha dzakawanda | C Channel | Ukobvu hwakakura hunopa rutsigiro rwakasimba rwekumira kune masisitimu epasi anorema. |

4. Kuongorora Kushanda Nemari Uye Kuvaka
Ruzivo rwemusika rwegore ra2026 runoratidza kuti kukwira kwemitengo yevashandi kwakaita kuti kurongeka kwekuisa zvinhu kuve chinhu chakakosha.
- Kumhanya Kwekuisa: C Purlins dzinowanzo bhombwa uye kubatanidzwa nemabhouroti, zvichiita kuti kuvaka kuwedzere 30% kupfuura C Channels, izvo zvinowanzoda kusungirirwa zvakanyanya.
- Mari Yekutakura Zvinhu: Sezvo C Purlins iri 1/3 kusvika 1/2 chete yehuremu hweC Channels, inopa mukana wakakura wekutakura zvinhu mukutengeserana kwenyika dzese, zvichibvumira vatengi kuwedzera nzvimbo yekutakura zvinhu.
Kune mapurojekiti a2026 anokoshesa kukurumidza uye kuderedza huremu (senge mapurazi ezuva nematura), C Purlin ndiyo sarudzo yepamusoro. Zvisinei, kune mafemu eindasitiri ane mabasa akawanda uye rutsigiro rwenhurikidzwa dzakawanda, C Channel yechinyakare inoramba iriyo chiyero cheindasitiri chekugara kwenguva refu uye kusimba.
