M'magawo a nyumba zomangira, kupanga zida zapakhomo, komanso kukongoletsa ndi kukonzanso,Choyimbira chachitsulo cha PPGLikukhala chinthu chomwe chimakonda kwambiri pa ntchito zambiri chifukwa cha kukana dzimbiri komanso kukongoletsa kwake. Komabe, chifukwa cha mitundu yosiyanasiyana ya zinthu zopangidwa ndi PPGL zomwe zili pamsika, momwe mungasankhire mtunduwo molondola, lamulirani mtengo wake.Koyilo ya PPGL, ndikuwonetsetsa kuti kugwiritsa ntchito nthawi yayitaliPepala lokhala ndi utoto wa PPGLNdi nkhani zazikulu zomwe wogula aliyense amadandaula nazo.
Chophimba chachitsulo cha PPGL chimapangidwa pogwiritsa ntchito pepala lachitsulo lopakidwa ndi aluminiyamu-zinc ngati maziko. Pambuyo pochotsa mafuta ndi kusintha pamwamba, chimakutidwa ndi gawo limodzi kapena angapo a zokutira zachilengedwe kenako nkuphikidwa pa kutentha kwakukulu kuti chiume. Mu kapangidwe kameneka, zokutira za aluminiyamu-zinc zomwe zili pansi pake zimagwira ntchito ngati chotchinga chachikulu chotsutsana ndi dzimbiri, pomwe zokutira zachilengedwe pamwamba pake zimagwira ntchito zonse ziwiri zoteteza komanso zokongoletsera. Ndi njira yotetezera iwiriyi yomwe imawonjezera kwambiri kukana dzimbiri kwa chophimba cha PPGL, ndipo nthawi yake yeniyeni yogwirira ntchito ndi yayitali pafupifupi nthawi 1.5 kuposa ya zophimba wamba zachitsulo zopakidwa ndi aluminiyamu-zinc.

Pogula pepala lokhala ndi utoto wa PPGL, tikulimbikitsidwa kuganizira mfundo izi mokwanira: Choyamba, kusankha mtundu wa utoto - polyester (PE) ndikoyenera malo wamba amkati, silicone-modified polyester (SMP) ndikoyenera pazochitika zakunja, pomwe polyester yolimbana ndi nyengo (HDP) kapena polyvinylidene fluoride (PVDF) ndizomwe zimasankhidwa kwambiri m'mphepete mwa nyanja ndi madera omwe ali ndi kuwala kwamphamvu kwa ultraviolet. Kachiwiri, kufananiza kwa zinthu za substrate, kuphatikiza makulidwe, m'lifupi, ndi zofunikira zapadera pa kulemera kwa utoto wa aluminium-zinc. Pomaliza, kulingalira kwaMtengo wa koyilo wa PPGLOgulitsa zinthu zabwino ayenera kukhala ndi mwayi wopereka njira yabwino kwambiri yotsimikizira ubwino ndi kuwongolera ndalama.
Kuyambira pomwe idakhazikitsidwa kumayambiriro kwa zaka za m'ma 1980, gulu la ZZ Group lakhazikika ku Yangpu District, Shanghai. Tsopano lakula kukhala gulu lalikulu la mabizinesi lomwe limaphatikiza malonda a zitsulo, kukonza ndi kugawa, kugwiritsa ntchito zinthu zopangira, chitukuko cha nyumba ndi ndalama. Ndi ndalama zolembetsedwa za RMB 200 miliyoni, lakhala bizinesi yotsogola mumakampani opanga zinthu zachitsulo ku China. Gululi lalandira ulemu wambiri motsatizana kuphatikizapo "Mabizinesi 100 Okhulupirika Kwambiri mu National Steel Trade Logistics" ndi "Mabizinesi 100 Apadera Kwambiri ku Shanghai mu Steel Trade".
Podalira maziko ake olimba a mafakitale komanso njira yowongolera bwino khalidwe, ZZ Group ipitiliza kupereka ma coil achitsulo apamwamba a PPGL ndi mapepala okhala ndi utoto wa ppgl kwa makasitomala athu. Kaya mukudera nkhawa ndi kuchuluka kwa mtengo ndi magwiridwe antchito a ma coil a ppgl kapena mukufuna makonda a ma coil a PPGL, tidzapereka ntchito zaukadaulo kuti tikupangitseni kukhala ndi phindu.
