Black round steel pipes supplied by Hebei Sinostar Trading Co., Ltd. are manufactured from carbon steel grades Q195, Q235, Q345 and A53 (A/B) using ERW technology. The product range covers outer diameters from 9 mm to 90 mm, wall thicknesses between 0.45 mm and 2.0 mm, and standard lengths of 4 m to 12 m. All pipes meet ASTM A53‑2007 and GB/T 3091‑2008 specifications, providing a reliable option for structural and low‑pressure fluid transport. The supplier lists the pipes under a black mill‑scale finish that protects the steel during handling.
These pipes are typical of the low‑pressure carbon‑steel segment where dimensional tolerances of ±0.2 mm are common and pressure ratings of PN6 (0.6 MPa) are standard for Q235 grades. Industry practice also includes a tensile strength of about 370 MPa for Q235 and up to 470 MPa for Q345, giving the product sufficient strength for scaffolding and fencing applications. The manufacturing process, electric‑resistance welding, yields a smooth internal surface suitable for conveying water, air or mild chemicals without additional coating. Suppliers often ship the pipes in bundles of ten metres, strapped and shrink‑wrapped on pallets for overseas freight.
Importers typically use these pipes in construction projects, agricultural irrigation, and temporary structures where cost‑effective strength is required. Buyers such as contractors, distributors and fabricators look for consistent wall thickness, verified standards compliance and clear packaging details before placing an order. While Hebei Sinostar does not publish a minimum order quantity, potential buyers should request bulk pricing, Incoterms and payment terms directly. Confirm the lead time, inspection protocol and any required certification before finalising a contract.

Before placing an order, verify that the product dimensions, material grades and compliance with ASTM A53‑2007 and GB/T 3091‑2008 are documented. Request a mill test report and a dimensional inspection certificate to ensure the pipes meet your project specifications.
Confirm the preferred Incoterm, typical lead time and payment method with Hebei Sinostar before signing a contract. Many buyers arrange FOB Shijiazhuang or CIF Shanghai, but the exact terms should be agreed in writing. Clarify whether the supplier can provide pallet‑level loading or container‑wide stowage details.
Arrange a third‑party inspection at the factory or at the port of loading to check wall thickness, surface finish and dimensional accuracy. A pre‑shipment inspection report and a certificate of conformity are standard documents that help avoid disputes after shipment.
