Import Forged Hollow Bars — Buy in wholesale FOB from Supplier in China

The Forged Hollow Bars offered by Tiptop Machinery Co., Ltd. are produced from structural carbon steel or low‑alloy steel grades using open‑die or closed‑die forging. With an annual forging capacity of 10,000 tons, the company can deliver a broad selection of hollow‑section profiles to meet demanding engineering requirements. Each bar is machined to precise bore dimensions and undergoes normalising and tempering heat treatment to achieve consistent mechanical properties. The supplier is based in Xi’an, Shaanxi Province, China.

Typical industry specifications for hollow bars include outer diameters from 30 mm to 200 mm and wall thicknesses between 5 mm and 20 mm, providing a favourable strength‑to‑weight ratio for applications such as drive shafts, hydraulic cylinders and spindle components. Tensile strengths of 650 MPa or higher are common for the low‑alloy grades, and the forged microstructure offers excellent fatigue resistance. The bars are supplied with ultrasonic testing (UT) and magnetic‑particle testing (MT) reports, complying with international quality standards for critical load‑bearing parts. Tiptop’s material inventory also covers stainless and non‑magnetic steels, allowing customers to select the most suitable alloy for their design.

Buyers such as OEM manufacturers, machinery builders and infrastructure contractors typically import these bars for high‑performance assemblies where weight reduction is essential. Trade arrangements are usually negotiated on FOB or CIF terms from the nearest Chinese port, with the possibility of custom packaging to protect the hollow sections during transit. Prospective purchasers should ask for the supplier’s chemical composition report, heat‑treatment record and dimensional inspection certificate before finalising the order. Payment is often handled via a letter of credit or telegraphic transfer after verification of the supplied documentation.

Tiptop Machinery Co., Ltd. is registered in Xi’an, Shaanxi Province, China (postal code 710075). The company holds a harbor‑level trust rating and is listed as an imported‑tier supplier, though the current response rate on the platform is zero. Its registered address is provided in the listing, confirming its operational base in central China.

The firm manufactures a broad range of forged components, including hollow bars, drilling stabilisers and well‑head forgings. It employs more than ten scientific and technical personnel and maintains an extensive inventory of raw steels covering carbon, alloy, stainless and non‑magnetic grades. Production processes include EAF, ladle furnace, vacuum degassing, forging, normalising, tempering, rough machining and precision machining. Test reports such as chemical composition, physical properties, heat‑treatment and dimensional inspection are generated for each batch, though specific certifications are not disclosed in the public profile.
