Ibhodi yokugcina i-polyurethane ebandayo isebenzisa i-Polyurethane ekhanyayo njengento yangaphakathi.I-advanteji ye-polyurethane yinto egqwesileyo yokushisa ubushushu.Ingaphandle yebhodi yokugcina ebandayo ye-polyurethane ihlanganiswe ne-galvanized color plate plate.it inokuthintela ukwanda kobushushu obubangelwa ngumahluko wokushisa ngaphakathi nangaphandle kwebhodi yokugcina ebandayo, ukuze wenze ukugcinwa okubandayo ngakumbi ukonga amandla,ukuphucula ukusebenza kakuhle kogcino olubandayo.
