Tele masani:
Matou te tuʻuina atu oloa i foliga o le uaea, uaea mafolafola, strip.We mafai foi ona faia mea faʻapitoa e tusa ai ma talosaga a le tagata faʻaoga.
Malamalama, fa'afefeteina, uaea vaivai–0.025mm~5mm
Acid pickeling uaea paepae:1.8mm~10mm
Uaea uaea: 0.6mm~10mm
Uaea mafolafola: mafiafia 0.05mm ~ 1.0mm, lautele 0.5mm ~ 5.0mm
Fa'agasologa:
Uaea: Sauniuniga o meafaitino → liusuavai → toe liusuavai → faʻamalosi → taʻavale vevela → togafitiga vevela → togafitiga luga → tusi (taʻavale) → maeʻa togafitiga vevela → asiasiga → afifi → faleteuoloa
Fa'ailoga oloa:
1) Lelei faʻamaʻi faʻamaʻi ma le malosi faʻainisinia i le vevela maualuga;
2) maualuga resistivity ma maualalo vevela coefficient o tetee;
3) Toe fa'aleleia lelei ma fa'atinoina galuega;
4) Excellent uelo performace
