Monga mtundu watsopano wazinthu zophatikizika za polima, zokongoletsa zakunja zamatabwa zapulasitiki zikuwonekera mozungulira inu ndi ine.Makhalidwe ake abwino kwambiri odana ndi corrosion, anti-mildew ndi anti-aging, komanso makhalidwe osafota komanso osasintha, akhala akudziwika ndi ambiri ogwiritsa ntchito.Mukayika matabwa a pulasitiki akunja, cholumikizira ndichofunikira chofunikira kwambiri;ndiye, tiyenera kukhazikitsa joist?
Mukayika keel, mtunda wapakati pa ma joists nthawi zambiri umadalira makulidwe a WPC Decking, pomwe makulidwe a Composite Decking ndi ochepera 25mm, mtunda wapakati pa ma joists sungathe kupitilira 250mm, ndipo mipata yotalikirapo yolumikizana siyingadutse 400mm.
Nthawi zambiri, tikayika joist, tidzakumana ndi zotsatirazi;
1. Mukayika matabwa oyendera maulendo oimitsidwa pamayiwe ndi nyanja kapena malo osungirako zachilengedwe, mbewu zaulimi, m'pofunika kusamalira maluwa ndi zomera, kapena pamene nyanja ndi maiwe sangagwiritsidwe ntchito pa ngalande zazikulu ndi kuthira konkire, zomangira kanasonkhezereka pansi akhoza mwachindunji zomangira mkati. Mobisa, ndiye kuwotcherera kanasonkhezereka chitoliro joist pansi wononga.Ngati waikidwa m'nyanja kapena dziwe, kapena ngati mpweya wozungulira chinyezi ndi wokwera, tikulimbikitsidwa kusankha otentha-kuviika kanasonkhezereka mapaipi lalikulu kupewa dzimbiri.

2. Pansi pali maziko a konkire;konkire imayikidwa, ndipo makulidwe a konkire si osachepera 8mm;ndiye, titha kugwiritsa ntchito mwachindunji mapulagi okulitsa apulasitiki kukonza matabwa apulasitiki pansi pa konkire
3. Kwa nthaka yoyera yamatope ndi malo oyika pansi ayenera kukwezedwa, choyamba tikhoza kukumba dzenje la maziko kuti tiyikepo konkire ndi mizati ya mapaipi pansi.Nthawi zambiri, m'mimba mwake ndi kuya kwa dzenje la maziko sizikhala zosachepera 300mm, zomwe zimagwiritsidwa ntchito ngati mzati.Mafotokozedwe a chitoliro cha malata si osachepera 60 * 60mm, ndipo makulidwe a khoma la chitoliro ndi osachepera 2mm;kutalika pakati pa ndime ndi mzati kumayendetsedwa mkati mwa 1800mm;pambuyo pa mzati wophatikizidwa kale, chitoliro chopangidwa ndi galvanized chimawotchedwa pamzati, ndipo mafotokozedwe akulimbikitsidwa kukhala 40 * Pamwamba pa 60mm.
