Indwangu yesihlungi yentambo ye-fiberglass eyenziwe ngentambo ye-weft eyenziwe ngobuningi. Ngenxa yentambo enoboya, le mikhiqizo inokusebenza kahle kokuhlunga nokuvumela ukuthi kudlule, okunganciphisa ukumelana nokuhlunga futhi kwandise ukuhlunga kungabi ngaphezu kuka-99.5%. Lezi zindwangu zingakwazi ukwamukela kahle izicelo zokuhlunga ezishisayo njenge-cement, i-carbon black, insimbi, i-metallurgy, izimboni zamandla nezimboni zamalahle.
