Koluse uamea fa'apalapala fa'a sikula fa'apipi'i ose masini fa'afeso'ota'i vaega ma galuega tauave ma uiga nei:
1. Fa'atinoga fa'amau lelei: O le koluse lapo'a mafolafola fa'ato'a fa'amau fa'amau fa'amau e faia i mea maualuga-malosi, lea e mafai ona fa'amuta lelei vaega eseese fa'atasi ma tausia le mautu o meafaigaluega.
2. Fa'afaigofie ona fa'a'ese'ese: Fa'atasi ai ma lona ulu fa'apitoa, e mafai ona fa'amauina pe fa'a'ese'ese i le fa'aogaina o se sikulivili, fa'asaoina le laasaga o le mua'i tu'i, fa'afaigofie ona fa'aoga ma fa'asaoina taimi.
3. Malosi tetee corrosion: Koluse foliga mafolafola ulu fao sikulima e masani lava ona faia i mea maualuga-lelei, ma o le i luga e togafitia chemically e fausia ai se ata tifaga oxide galvanized uliuli, lea ei ai ele lelei ma anti-corrosion aafiaga ma e mafai ona faaaoga mo se taimi umi i siosiomaga faigata.
4. Faiga faigofie: e aofia ai le ulu, 'au, ma vaega filo, faigofie ona gaosia ma faʻaoga.
5. Faʻatatau lautele: E iai le tele o faʻaoga i masini masini, fausaga o fale, meafale gaosi oloa, oloa faʻaeletoroni, aerospace ma isi fanua.
6. Malosi sili: O le koluse mafolafola foliga ulu e mafai ai e le koluse foliga mafolafola tapping sikulima e sili atu le auai i mea faavae, faia le sootaga sili atu mautu ma faatuatuaina, ma sili atu le gafatia e tauave, ma sili atu tensile ma sele teteʻe nai lo sikuli masani.
7. Maualuluga maualuga: O le ulu mafolafola koluse fa'apena e fa'amautu le feso'ota'iga ma fa'atuatuaina, fa'aitiitia ai le avanoa e fa'amama.
