The primary difference lies in the thickness of the zinc coating. Our Pre-galvanized steel pipe has a zinc coating range of 40–220 G/M², while the Hot dip galvanized steel pipe features a thicker zinc coating of 220–350 G/M² to offer enhanced corrosion resistance.
We support a wall thickness range of 0.6mm to 20mm, outer diameters ranging from 1/2’’ (21.3mm) to 16’’ (406.4mm), and lengths between 1 to 14 meters according to specific customer requirements.
Since we are a direct factory, we bypass intermediary trading company markups, allowing us to pass the savings onto our customers. Additionally, we regularly update pricing in real-time based on the steel market rates.
Our standard delivery time is 25 days after receiving your deposit. We load shipments at Tianjin/Xingang Port, which is the largest port in Northern China, located just 40 kilometers from our factory.
We accept a 30% T/T deposit in advance, with the remaining 70% balance due after receiving the B/L copy. We also accept 100% Irrevocable L/C at sight, or 100% Irrevocable L/C 20–30 days after receiving the B/L copy.
Absolutely. We highly welcome on-site visits and quality inspections. Customers regularly visit our factory to inspect and verify their steel pipe orders after production is finalized.
