Sulfate Galvanized Conversion
Sulfate galvanized conversion is a hot‑dip zinc coating process applied to carbon‑steel pipe using a zinc sulfate flux. Threeway Steel Co., Ltd. manufactures these coated pipes in China. The product conforms to international standards such as ASTM A53 and BS 1387. The supplier is listed under the imported tier with a harbor trust rating.
Typical carbon‑steel grades used are ASTM A53 Grade B with a zinc coating thickness of 50 - 100 µm. Tensile strength of the base steel normally ranges from 380 to 420 MPa. The zinc layer provides corrosion protection that can last 40 - 60 years in moderate atmospheric conditions. Standard pipe diameters run from 25 mm to 600 mm with wall thicknesses between 2 mm and 20 mm.
These pipes are widely employed in water transmission, scaffolding, fencing and structural construction projects. Procurement usually involves containerised bundles of about 500 kg, with buyers arranging FOB or CIF shipments. Specific MOQ, lead‑time and payment conditions are not disclosed and should be verified directly with Threeway Steel.
