Xaaladaha Kaydinta
Waxa lagu kaydiyay meel qabow oo hawo leh, meel wax lagu kaydiyo oo guriga ka fog, ayaa la sameeyay.Qalabka dab-damiska iyo weelasha biyaha xiran ee ku habboon ayaa diyaar ah.Weelooyin bir ah oo khafiif ah, aluminium ama naxaas ah ayaa diyaar ah.
U isticmaal aluminium, birta aan daahin, taangiyada birta ama caagga ah ama alaabada gubanaysa kaydinta iyo gaadiidka.Qolka leh heerkulka ugu sarreeya ee 20 ° C waa in lagu buuxiyaa weelal iyo tubooyinka.
