Kulongedza
Chitetezo Chokwanira: Mitanda ya I-imangirizidwa pamodzi ndi tarpaulin yokonzedwa ndi mapaketi a 2-3 desiccant; pepala lotsekera kutentha, loletsa mvula limatchinga chinyezi.
Kumanga Kwachitetezo: Zingwe zachitsulo za 12-16 mm kuzungulira mtolo uliwonse; zabwino kwa matani 2-3 ndi zida zonyamulira zogwirizana ndi US.
Zolemba Zomveka: Zinenero ziwiri za Chingerezi/Chisipanishi zili ndi giredi, zofotokozera, nambala ya HS, batch #, komanso zonena za lipoti la mayeso.
Kutetezedwa Kwambiri Yambiri: Mitanda yokhala ndi kutalika kwa ≥800 mm idakutidwa ndi mafuta owongolera ndipo idakulungidwa kawiri ndi tarpaulin.
Kutumiza
Kutumiza Kodalirika: Kugwirizana ndi zonyamulira zabwino kwambiri (MSK, MSC, COSCO etc.) kutsimikizira kutumiza kwachitetezo.
Kuwongolera Kwabwino: Njira ya ISO 9001; mizati imayang'aniridwa mosamala kuyambira pakuyika mpaka kunyamulira kuti iwonetsetse kuti ikufikirani bwino, kupanga projekiti yopanda zovuta.
Q: Kodi miyeso yanu ya I-I ku Central America ndi iti?
A: I Beams yathu ikugwirizana ndi ASTM A36 & A572 Grade 50 yomwe imagwiritsidwa ntchito kwambiri ku Central America. Tithanso kupereka zinthu zomwe zimagwirizana ndi zofunikira zakomweko (mwachitsanzo, NOM yaku Mexico).
Q: Nthawi yayitali bwanji yotumiza ku Panama?
A: Transit Time Sea Freight kuchokera ku Tianjin Port kupita ku Colon Free Trade Zone masiku 28-32 wks. Kupanga ndi kutumiza kwathunthu ndi masiku 45-60. Kutumiza mwachangu kungakonzedwenso.
Q: Kodi mumathandiza ndi chilolezo cha kasitomu?
A: Inde, akatswiri athu amalonda adzachita zolengeza, kulipira msonkho & ntchito zonse zamapepala kuti atsimikizire kuti kutumiza bwino.
