Yintoni esebenzayo kunye nesiphumo esivela kumthunzi we-V weprofayili ekhokelwa yi-China aluminium ekhokelwa ngumenzi weprofayili
Iprofayili yokukhanya kwe-V yomthunzi yenye yeyona nto ibalaseleyo kunye neyona nto idumileyo yoyilo lweeprofayili ze-aluminium ezikhokelela kumzi-mveliso wethu we-aluminium..
Umthunzi we-V okhokelela kwiprofayili yokukhanya kwe-aluminium kunye nesigqubuthelo sepc esimnyama namhlophe sinokwenziwa ngamaqhekeza nganye kwi-1m kunye ne-2m., kunye ne3m.
Kukho ngaphezulu kwe-10000m yesitokhwe kumzi-mveliso wethu weprofayile ekhokelwa ngokwesiqhelo kumthunzi we-v, ukuba imfuneko iodolo kunye nenqanawa ekhawulezayo, usitsalele umnxeba okanye usithumelele i-imeyile.
