Buy & Import Pre-stretching plate from Chongqing Guosheng Aluminum Co., Ltd - Wholesale Supply

The Pre‑stretching plate is a carbon‑steel plate intended for the hot‑stretch forming stage in flange manufacturing. It is supplied in the grades Q235B and Q345B as specified by the supplier. The product meets the Chinese standard Q/SWA10204‑2003, which governs the mechanical properties of steel plates used in pressure vessel and pipe‑fitting applications. The plate is offered in standard thicknesses and dimensions suitable for international shipping.

Carbon steel grades Q235B and Q345B provide typical yield strengths of 235 MPa and 345 MPa respectively, a common choice for components that must endure high forming pressures. In the industry, pre‑stretching plates are frequently supplied in thicknesses from 8 mm to 25 mm and lengths up to 6000 mm, with surface finishes that minimise friction during the stretching process. Typical weight is about 78 kg per square metre for 10 mm thickness, aligning with standard handling practices.

These plates are mainly purchased by manufacturers of ring‑type flanges and pipe fittings for oil, gas and chemical pipelines. Buyers often request the plates together with machining services and negotiate bulk purchase terms such as FOB or CIF based on order volume. The supplier does not state a minimum order quantity, so importers should discuss batch sizes and delivery schedules directly with the factory. Payment is usually arranged via a letter of credit or advance, subject to mutual agreement.

Sourcing Pre-stretching plate from Chongqing Guosheng Aluminum Co., Ltd - China Import Guide

Verify that the plate’s grade and thickness meet the project’s mechanical requirements and that the product complies with Q/SWA10204‑2003. Request a mill test report and a dimensional inspection certificate before finalising the purchase. Confirm whether any surface‑treatment certifications are available if a specific finish is required.

Discuss the preferred Incoterms, such as FOB Chongqing or CIF a destination port, and ask the supplier for an estimated production lead time once the order details are settled. Clarify the payment terms, which are commonly arranged through a confirmed letter of credit, and ensure that the sales contract records all agreed conditions. Inquire about the availability of container loading versus break‑bulk shipping for the plate dimensions.

Arrange for a pre‑shipment inspection by a recognised third‑party agency to verify thickness, surface finish and material grade. Request the supplier’s quality management documents, including any ISO quality system certificates they may hold. Ensure that the export paperwork includes a certificate of conformity and all customs documentation required for importing steel plates into the buyer’s country.
