Kuwonjezeka kofulumira kwa madzi ogwiritsidwa ntchito m'mafakitale chifukwa cha chitukuko cha zachuma cha dziko kwapangitsa kuti pakhale kofunika kulimbikitsa kugwiritsa ntchito nsanja zoziziritsira ndi kukonzanso madzi a mafakitale ndi refrigeration pofuna kupulumutsa madzi, kuteteza chilengedwe ndi kuchepetsa kugwiritsa ntchito mphamvu. Zinsanja zozizira ndizitsulo zazikulu zotentha zomwe zimagwiritsidwa ntchito m'mafakitale amagetsi ndi mafakitale opangira madzi kuti azizizira, zomwe zimaziziritsa zipangizo zofunika pa ntchito za tsiku ndi tsiku.
Panthawi yogwira ntchito, zida zomangira zomwe zimagwiritsidwa ntchito munsanja zozizirira ziyenera kupirira madera osiyanasiyana, kuphatikiza kuukira kwamankhwala ndi kwachilengedwe komanso zovuta. Mbiri ya Pultruded glass fiber reinforced plastic (GFRP) ndi njira yabwino yopangira zida zoziziritsa za nsanja chifukwa champhamvu, kulemera kwake, komanso kukana dzimbiri, zomwe ndi chibadwa cha FRP. Kuphatikiza apo, pultrusion ndi njira zina zopangira FRP, monga phala lamanja kapena RTM, ndizopanda ndalama zambiri ndipo zimapereka magwiridwe antchito apamwamba.
● Kugwiritsa ntchito GFRP yopukutidwa ngati zida zomangira pansanja zozizirira kumapindulitsa kwambiri kuposa matabwa, konkire, ndi chitsulo.
● Mosiyana ndi matabwa, kusakhalapo kwa gawo lapansi la tizilombo tating'onoting'ono tagalasi ndi utomoni kumachepetsa kuwonongeka kwa biomass mu GFRP.
● GFRP imasonyeza kukana kwa mankhwala apamwamba poyerekeza ndi zitsulo ndi zipangizo za konkire.
● GFRP ndi yopepukanso poyerekeza ndi matabwa, zitsulo, ndi konkire.
● GFRP safuna kukonza ndipo zigawo zowonongeka zimasinthidwa mosavuta, zomwe zimapangitsa kuti ikhale yothandiza kwambiri komanso yotsika mtengo pomanga nsanja yozizirira.
Mu 2015, nsanja yozizirira ya projekiti ya Ningcoal idayamba kugwiritsa ntchito zida za FRP ngati njira yoyambira yothandizira. Ntchito ya Shenhua Ningxia Coal Group Liquefaction Indirect Liquefaction Project, yomwe imadziwika kuti "No.1 Project" yopangidwa ndi Ningxia Autonomous Region, ndiyo ntchito yayikulu yowonetsera malasha kumafuta ku China. Ili ku Ningdong Town Energy Chemical Base, Lingwu City, Ningxia, China, ndalama zonse za polojekitiyi zimakwana RMB 55 biliyoni ndipo zidapangidwa kuti zizipereka matani 4 miliyoni amafuta pachaka. Zinsanja zozizirirapo za minda yamadzi yoyamba ndi yachiwiri yozungulira matani 4 miliyoni/chaka chophatikizira malasha mosadukizadukiza ndi nsanja za FRP, zomangidwa pogwiritsa ntchito mbiri ya FRP yopangidwa ndi Spare. Nyumba zozizira za polojekitiyi 60 iliyonse imaphatikizapo matani pafupifupi 45 a FRP pultruded profiles pamapangidwe awo.
