About Tianjin Xuboyuan Iron & Steel Trading Co.,Ltd - Steel Supplier in China

Tianjin Xuboyuan Iron & Steel Trading Co.,Ltd operates from Tianjin, China and lists ten active products in its catalogue. The catalogue covers a range of steel items including finishing thread steel rebars, electro carbon steel sheet, annealed cold rolled steel coil, low carbon steel SAE 1006, Aluzinc steel coil, structural steel pipes and C channels, mild steel flat bars, prepainted and PPGI GI coils, a 22 gauge ridge roll, and hot rolled steel coils. Products are classified under HS code families such as 7208.90, 7209.18, 7210.61, 7210.70, 7216.33 and 7208.51, reflecting carbon steel, alloy‑coated and hot‑dip zinc coated grades. The top categories reported are Steel Coils, Agriculture, Steel, Steel Pipes and Steel Bars, indicating a focus on rolled and structural steel products.

Each listed item specifies material composition, for example the Aluzinc coil combines 55 % aluminum, 43.5 % zinc and 1.5 % silicon, while the low carbon SAE 1006 steel caps carbon at 0.08 % maximum. Structural steel items reference Chinese grades Q195, Q235, Q345, SS400 and A36, and the prepainted coils use DX51D base plate. The hot rolled coil is described as carbon structural steel covering grades Q195, Q235, A36, SS400, Q345 and ST37‑2. The product set therefore spans cold‑rolled, hot‑rolled, coated and rebars suitable for construction, manufacturing and pipe fabrication.

Product Range and Specialties of Tianjin Xuboyuan Iron & Steel Trading Co.,Ltd

The catalogue’s cold rolled steel coil (HS 7209.18) aligns with industry standards such as EN 10050 for cold‑rolled carbon steel, where thicknesses from 0.2 mm to 4 mm and widths up to 2 m are common. Low carbon SAE 1006 is comparable to ASTM A36 and GB Q235, offering a tensile strength around 400 MPa and elongation near 20 %. Aluzinc coated coils (HS 7210.61) meet the Z275 coating specification, delivering a zinc‑aluminum alloy layer of roughly 50 µm that improves corrosion resistance for building facades. Pre‑painted GI coils (HS 7210.70) follow the PPGI standard with a zinc coating of 120 g/m² and a polymer paint layer, typically used for roofing and wall panels. Hot rolled coils (HS 7208.51) are supplied in standard coil lengths of 6 m to 12 m, with thicknesses from 3 mm to 25 mm, conforming to ASTM A1011. The rebars and flat bars correspond to GB T 3591 and ASTM A615, with diameters ranging 6 mm to 32 mm for rebars and widths up to 200 mm for flat bars.

Trade and Export Information - Tianjin Xuboyuan Iron & Steel Trading Co.,Ltd

Chinese steel exporters such as this supplier commonly ship to Southeast Asian countries, the Middle East, East Africa and European Union members, where construction and infrastructure projects drive demand for cold‑rolled, hot‑rolled and coated steel. The HS codes listed (7208, 7209, 7210, 7216) fall under Chapter 72, which is subject to anti‑dumping investigations and may require a Certificate of Origin and a quality inspection report from agencies like SGS or Bureau Veritas. Buyers typically request ISO 9001 certification and compliance with ASTM or EN standards; while the supplier’s catalogue does not specify certifications, these documents are standard for the sector. Steel coils are usually exported on 20‑ft or 40‑ft containers or on bulk carriers, with coil lengths of 6 m to 12 m wrapped in protective film and strapped to pallets or bundled on steel supports. Common Incoterms include FOB Tianjin, CIF Shanghai or DDP for regional buyers, with freight forwarding handled by major Chinese logistics firms.

Sourcing from Tianjin Xuboyuan Iron & Steel Trading Co.,Ltd - Buyer Guidance

When sourcing steel from this supplier, buyers should ask for a Mill Test Certificate that details chemical composition, tensile strength and elongation for each grade, as well as a coating thickness report for Aluzinc and PPGI coils. A third‑party inspection report (e.g., SGS) confirming dimensions, weight per metre and surface quality should be obtained before shipment. Typical minimum order quantities are one standard coil (approximately 20‑25 tons) for rolled products, while rebars and flat bars may be ordered in 5‑ton batches. Lead times for Chinese manufacturers range from 30 to 45 days after order confirmation, depending on product thickness and coating process. Verify that the shipment paperwork includes the correct HS code, a Certificate of Origin and any required import permits for the destination country.

What steel grades are available in the cold‑rolled coil offering (HS 7209.18)?

The cold‑rolled coil is listed as low carbon steel, comparable to Chinese Q235 and ASTM A36, with typical thicknesses from 0.2 mm to 4 mm and tensile strength around 400 MPa.

Does the Aluzinc steel coil meet any coating standards?

The Aluzinc coil follows the Z275 specification, providing an alloy coating of approximately 55 % aluminum and 43.5 % zinc, which is widely accepted for corrosion‑resistant building applications.

Which documents should be requested before confirming an order?

Buyers should request a Mill Test Certificate, a third‑party inspection report, a Certificate of Origin, and, if required, an ISO 9001 compliance statement.

What is the typical minimum order quantity for hot‑rolled steel coils?

The usual MOQ is one standard coil, which weighs about 20 to 25 tons and measures 6 m in length.

How are the steel coils packaged for export?

Coils are wrapped in protective film, strapped securely, and loaded on pallets or steel supports inside 20‑ft or 40‑ft containers, or on bulk carriers for larger volumes.

What lead time can be expected for the pre‑painted PPGI GI coils?

Lead time is generally 30‑45 days after order confirmation, depending on the coating schedule and coil dimensions.

Which HS codes apply to the structural steel pipes and C channels?

The structural steel pipes and C channels are classified under HS 7216.33, covering hot‑rolled steel sections.
