Isakhiwo sokwakha
Ubunjiniyela Bebhuloho
Ukwesekwa Kwezisetshenziswa Zezimboni
Ukuqiniswa Kwesakhiwo
1) Ihhovisi Legatsha - Usekelo lwabakhuluma iSpanishi, usizo lokugunyazwa kwamasiko, njll.
2) Ngaphezu kwamathani angu-5,000 esitoko esitokweni, anosayizi abahlukahlukene
3) Ihlolwe izinhlangano ezigunyaziwe njenge-CCIC, SGS, BV, ne-TUV, ngamaphakheji ajwayelekile angasolwandle
Ukupakisha
Ukuvikelwa Okugcwele: I-I-imishayo igoqwe ngeseyili kanye namaphakethe we-desiccant we-2-3; amashidi kaseyili avala ukushisa, angangenwa yimvula avimbela umswakama ukuba ungangeni.
Ukuhlanganisa Okuvikelekile: Inqwaba ngayinye isongwe ngezintambo zensimbi ezingu-12–16 mm; kulula ngamathani angu-2–3 kanye nemishini yokuphakamisa ehambisana ne-US.
Ukulebula Okusobala: Amalebula ezilimi ezimbili (isiNgisi neSpanishi) anebanga, imininingwane ecacisiwe, ikhodi ye-HS, iqoqo # kanye nereferensi yombiko wokuhlola.
Ukuvikelwa kwephrofayili ephezulu: I-I-beams ≥800 mm yaphathwa ngamafutha okuqondanisa bese isongwa ngeseyili kabili.
Ukulethwa
Ukuthumela Okuthembekile: Ukubambisana kwabathwali abahamba phambili (MSK, MSC, COSCO ect) ukuze kuqinisekiswe ukuthunyelwa kokuphepha.
Ukulawulwa Kwekhwalithi: Uhlelo lwe-ISO 9001; Imishayo ilawulwa ngokuqinile kusukela ekupakishweni ngezinto zokuhamba ukuze kuqinisekiswe ukuthi ifika iphelele, okukuvumela ukuthi ube nephrojekthi engenazinkinga.
Q: Yiziphi izindinganiso ze-I-imishayo yakho e-Central America?
A: I-I Beams yethu ihambisana ne-ASTM A36 & A572 Grade 50 evuna i-Central America. Kungenzeka futhi ukuhlinzeka ngemikhiqizo ehlangabezana nezindinganiso zikazwelonke (isb, i-MEXICO NOM).
Q: Isikhathi esingakanani sokulethwa ePanama?
A: Transit Time Sea Freight kusuka echwebeni lase-Tianjin kuya e-Colon Free Trade Zone izinsuku ezingama-28–32 wks. Ukukhiqizwa nokulethwa sekukonke kuyizinsuku ezingama-45-60. Ukulethwa okuphuthumayo kungahlelwa, futhi.
Umbuzo: Ingabe uyasiza ngokugunyazwa kwentela?
IMP: Yebo, abathengisi bethu abangochwepheshe bazokwenza isimemezelo samasiko, bakhokhe intela nawo wonke umsebenzi wephepha ukuze baqinisekise ukulethwa ngokushelela.
