Hongguan Steel Group Co. Ltd. offers stainless steel square and rectangular tubes that meet ASTM A554 and EN 10219 standards. Square sections are available from 10 × 10 mm up to 300 × 300 mm, while rectangular sections range from 10 × 20 mm to 120 × 180 mm. The tubes are produced in grades 304 and 316, a chrome‑nickel alloy, and can be supplied in lengths as required or in the common 6 m size. Manufacturing is located in Jinan, Shandong Province, China.
Both 304 and 316 grades deliver the corrosion resistance expected of austenitic stainless steels, and typical surface finishes include polishing, annealing, pickling and a bright coat. Dimensional tolerances are generally ±0.3 mm for width and height and ±0.5 mm for wall thickness, which conforms to international practice for structural hollow sections. Typical tensile strength values are about 520 MPa for grade 304 and 580 MPa for grade 316, and the material density is roughly 7.93 g/cm³, matching standard austenitic steel properties.
The tubes are suited to construction scaffolding, handrails, furniture frames, decorative metalwork and water‑supply structures, making them popular with contractors, fabricators and OEMs. Hongguan notes that shipments are packed in waterproof paper and steel strip, a configuration that protects the product during sea freight. The supplier cites a shipment window of 7‑15 working days after receipt of deposit or L/C, but buyers should verify the exact lead time for their order. Minimum order quantities and pricing are not disclosed in the listing and must be discussed directly with the supplier.

When initiating a purchase, ask Hongguan for the latest mill test report that details chemical composition, mechanical properties and dimensional tolerances of the specific grade and size you require. Request copies of any ISO or SGS certificates referenced by the supplier and verify that they are valid for the product batch you will receive.
Confirm the preferred incoterm - FOB or CIF - as well as the expected freight cost and delivery schedule. The supplier mentions a typical shipment window of 7‑15 working days after receipt of deposit or L/C, but you should obtain a firm lead‑time estimate for your order and discuss acceptable payment methods such as T/T against documents or a confirmed L/C.
Arrange a pre‑shipment inspection by a recognised third‑party agency. Inspectors should verify surface condition, measure dimensions, check wall thickness and perform a corrosion resistance test. Ensure that the final shipping documents include the inspection report, mill test report and any certificates before the goods are released.
