The product range offered by Henan HZZ Iron and Steel Co., Ltd. comprises carbon structural steel plates in Q345B, Q345C and Q345D grades, all manufactured to the GB/T 1591 standard. These hot‑rolled plates are supplied in thicknesses that typically span from 5 mm to 200 mm and can be cut to lengths up to 12 000 mm, with widths commonly up to 2 500 mm. Each grade provides a specific impact‑toughness rating: Q345B at room temperature, Q345C down to 0 °C and Q345D to - 20 °C. The plates are produced by Chinese mills and are recognised as a cost‑effective alternative to comparable international grades.
Typical chemical composition for the grades includes carbon up to 0.20 %, manganese up to 0.90 % and silicon not exceeding 0.55 %, delivering a typical tensile strength around 470 MPa. The hot‑rolled finish offers a uniform surface suitable for welding and forming operations. These specifications make the steel suitable for high‑rise building frames, bridge components and heavy‑duty machinery parts where strength and toughness are critical. Buyers benefit from the material’s good weldability and formability across a range of fabrication processes.
Importers such as construction contractors, bridge engineers and equipment manufacturers commonly source these plates for structural projects. Trade terms are flexible, with FOB and CIF options mentioned in the source, and packaging is provided in standard export bundles to protect the plates during transit. Prospective buyers should request detailed mill certificates, dimensional tolerances and confirm lead‑time expectations before finalising the purchase.

Henan HZZ Iron and Steel Co., Ltd. is located in Jincheng International Building 6, Zhengzhou, 450000, Henan, China. The supplier carries a harbor trust tier and is classified as an imported tier, although its response rate is currently recorded as 0 % with no recent replies.
The company supplies carbon structural steel plates in Q345B, Q345C and Q345D grades sourced from Chinese mills. It does not publish minimum order quantities, lead times or pricing, so interested buyers should request those specifics directly from the sales team.
Q345B, Q345C, and Q345D are high-strength carbon structural steel plates manufactured to GB/T1591 standard, widely used in construction, bridge engineering, and heavy machinery fabrication. These grades differ primarily in delivery conditions and impact toughness: Q345B offers solid room-temperature strength, Q345C is suitable for low-temperature applications down to 0 degrees C, and Q345D performs reliably at minus 20 degrees C. Available in hot-rolled coils or sheets, these plates are a staple in global steel trade, particularly in export markets across Southeast Asia, the Middle East, and Africa where infrastructure demand is strong.

Before placing an order, importers should verify the plate dimensions, including thickness, width and length, against the supplier’s specifications. Request the latest mill certificates and a mill test report that details chemical composition, tensile strength and impact‑toughness. Confirm the hot‑rolled surface condition and any additional processing requirements. Early verification helps avoid receiving material that does not meet project criteria.
Logistics arrangements can be negotiated, with FOB and CIF terms available according to buyer preference. Ask the supplier to provide an estimated lead time for production and container loading, as the listing does not state a fixed schedule. Payment terms are typically agreed in advance and may involve a letter of credit or other mutually acceptable method.
Quality control can be strengthened by commissioning a third‑party inspection, for example by SGS or a comparable agency, prior to shipment. Ensure the inspection covers dimensional accuracy, surface finish and mechanical properties as documented in the mill test report. Request accompanying documents such as the certificate of origin, packing list and insurance certificate to smooth customs clearance and confirm compliance with the importing country’s regulations.
