Kunezinhlobo eziningana zezinkampani noma abakhiqizi embonini yezibambo zomnyango:
Okokuqala ukulingisa imiklamo yezinye izinkampani noma abakhiqizi. Imikhiqizo yezinkampani noma abakhiqizi abanjalo ayinayo imiklamo emisha kanye nekhono lokuthuthukisa imikhiqizo emisha.
Okwesibili yizinkampani noma abakhiqizi abahlinzeka kakhulu ngezibambo zeminyango ze-aluminium alloy, izibambo zeminyango zensimbi engagqwali noma izibambo zeminyango zensimbi. Lezi zinhlobo zemikhiqizo zibhekwa kakhulu njengenani elikhulu, ezithinta intengo, futhi azidingi ukuthuthukiswa komkhiqizo kanye nokusungula izinto ezintsha.
I-YALIS, umkhiqizi wezibambo zeminyango ze-zinc alloy kanye nezixazululo zehadiwe yeminyango, hhayi nje kuphela ngomthamo wokuthuthukiswa komkhiqizo wezinhlobo ezahlukene zamakhasimende kanye nezimo zokusetshenziswa kweminyango, kodwa futhi nangomthamo wokumaketha nokukhushulwa ezimakethe ezahlukene.
Owesithathu uhlobo lomkhiqizo oluhamba phambili lwase-Italy. Imikhiqizo yabo yenziwe kakhulu ngethusi. Uhlobo lwabo lunedumela eliphezulu emhlabeni wonke. Kodwa-ke, imikhiqizo yabo ingatholakala kumakhasimende amancane--- amakhasimende asezingeni eliphezulu kakhulu.
