Vaaiga lautele
O lo'o pipii i luga o le fa'atonuga "Fa'amaoni, to'aga, sogasoga, fa'afou" e maua ai fa'afitauli fou i taimi uma. E manatu i fa'amoemoega, manuia o lona manuia patino. Se'i o tatou fausia lima manuia i le lumana'i mo seamless Carbon Steel Fluid Pipe, O lea ua tatou atia'e se igoa fa'atatau i le tele o tagata fa'atau. Tulaga lelei & tagata fa'atau muamua e masani lava o la tatou sailiga faifaipea. Matou te le fa'asaoina ni taumafaiga e fesoasoani i le faia o ni fofo sili atu. Vaavaai atu i le galulue faatasi mo se taimi umi ma le manuia soofaatasi! E oo mai i le taimi nei ua auina atu a matou oloa i Europa i sasae, Sasaʻe Tutotonu, Sautesasae, Aferika ma Amerika i Saute ma isi. Ua 13 tausaga o matou faʻatau faʻatau ma faʻatau i vaega Isuzu i le fale ma fafo ma le umiaina o faiga faʻaonaponei eletise Isuzu siaki. Matou te faʻaaloalo i le matou pule autu o le Faʻamaoni i pisinisi, faʻamuamua i le tautua ma o le a matou faia le mea sili matou te mafaia e tuʻuina atu ai a matou tagata faʻatau oloa maualuga ma auaunaga sili.
