About Shandong Hengfeng Group - Steel Coils Supplier in China

China, specifically the Shandong region, hosts twelve listed product lines under Shandong Hengfeng Group. The catalogue spans steel‑based items such as Galvanized Coated Plates, Aluminum‑Zinc‑Silicon Coated Plates (HS 7210.61), Roof Sheet Galvanized Steel Coils, High‑strength Galvanized Tile, Cold Rolled Steel Coil (HS 7209.15), Hot Dipped Galvanized Steel Coils, Full Hard Galvanized Steel Coil, Rolled Galvanized Steel Coil, as well as non‑metal goods including Corrugated Board, Color‑coated Sheets, Cold‑rolled Plates and Guardrail Plate Fittings. Each steel product is identified by an HS‑code in the 7210 or 7209 chapters, indicating hot‑dip or cold‑rolled steel articles. The material descriptions specify carbon steel grades Q195, Q235, S350GD and coating systems such as Z275 zinc or Al‑Zn‑Si alloy. The non‑metal items are listed without HS codes in the provided data.

The supplier’s active product count of twelve reflects a focus on building‑materials steel and ancillary sheet products. The inclusion of both coated plates and various coil formats suggests capability to serve roofing, construction, and industrial equipment sectors. The catalogue also lists corrugated board and color‑coated sheets, indicating a secondary line in paper‑based or metal‑coated sheet products. No additional certifications or client references are stated in the supplied facts.

Product Range and Specialties of Shandong Hengfeng Group

Shandong Hengfeng Group lists eleven steel‑related items and three paper‑based products. The steel portfolio includes hot‑dip galvanized coils (HS 7210.49) typically produced to ISO 1461 surface‑treatment standards, with coating weights ranging from 70 to 150 g/m² and tensile strengths aligned with ASTM A123 or GB/T 9775. The Aluminum‑Zinc‑Silicon coated plates (HS 7210.61) commonly meet EN 14509 specifications for Al‑Zn‑Si alloy layers, offering corrosion resistance for architectural panels. Cold‑rolled steel coils (HS 7209.15) are usually supplied in thicknesses between 0.5 mm and 2.0 mm with surface roughness Ra ≤ 0.8 µm, conforming to ASTM A568 or GB/T 6990. High‑strength galvanized tiles and full‑hard coils use Z275 zinc coating, a standard zinc mass of 275 g/m², suitable for high‑load roofing applications.

The three non‑metal items - Corrugated Board, Color‑coated Sheets and Guardrail Plate Fittings - are typical of construction‑related packaging and safety components. Corrugated board is generally produced to ISO 12048 strength classes (e.g., B‑flute, C‑flute) and can be coated for moisture resistance. Color‑coated sheets often follow ISO 10502 for pre‑painted metal, offering a range of RAL colours. Guardrail plate fittings are usually fabricated from cold‑rolled steel and may be hot‑dip galvanized for durability.

Trade and Export Information - Shandong Hengfeng Group

Chinese steel exporters routinely ship hot‑dip galvanized coils (HS 7210) to construction markets in Southeast Asia, the Middle East, Africa and South America, where roofing and infrastructure projects demand corrosion‑resistant profiles. The HS 7209 cold‑rolled steel category is frequently imported by automotive and appliance manufacturers in Europe and North America, who require tight dimensional tolerances and surface finish. Export logistics commonly involve 20‑foot or 40‑foot containers with coils wound on steel drums or palletised plates, protected by moisture‑resistant wrapping. Importers often request certificates such as ISO 9001 quality management, mill test certificates (MTC), and where applicable, CE marking for EU compliance.

China’s steel sector benefits from established port infrastructure and competitive freight rates, allowing CIF or FOB terms to be negotiated for major ports like Qingdao or Shanghai. Buyers of corrugated board and color‑coated sheets typically source from East Asian paper mills and metal‑coating facilities that meet ISO 9002 and FSC standards for sustainable sourcing. While Shandong Hengfeng Group’s specific certifications are not listed, the industry standard for these categories includes verification of coating weight, zinc mass, tensile strength and compliance with local environmental regulations such as China’s GB/T 10170 for galvanized steel.

Sourcing from Shandong Hengfeng Group - Buyer Guidance

When sourcing galvanized steel coils from Shandong Hengfeng Group, request a current Mill Test Certificate that details chemical composition, tensile strength, yield point and coating weight. Verify that the zinc coating conforms to Z275 or the stated g/m² range, and ask for a surface‑tension test report (ISO 1461) to confirm corrosion performance. For the Al‑Zn‑Si coated plates, obtain an alloy composition analysis and a coating adhesion test (ASTM B571) before confirming the order.

Buyers of the non‑metal items should ask for product specifications such as board flute type, burst strength (ISO 12048) for corrugated board, and colour code compliance (RAL or Pantone) for color‑coated sheets. Request packaging details - e.g., pallets wrapped in polyethylene film for coils or flat‑packed sheets - and confirm container loading plans to avoid damage. Prior to finalising a purchase, ensure that any required certifications (ISO 9001, CE, FSC) are provided as part of the documentation package.

What HS codes apply to the steel coil products listed by Shandong Hengfeng Group?

The roof sheet, high‑strength tile, hot‑dipped, full‑hard, rolled and other galvanized steel coils are classified under HS 7210.49, while the cold‑rolled steel coil is under HS 7209.15. The Aluminum‑Zinc‑Silicon coated plates use HS 7210.61.

Which steel grades are used for the galvanized coils?

The catalogue specifies carbon steel grades Q195, Q235 and S350GD as the base material for the various galvanized coil types.

What typical coating weight should a buyer expect for Z275 galvanized steel?

Z275 indicates a zinc coating mass of approximately 275 g per square metre, which is a common specification for high‑strength roofing and structural steel.

What documentation is normally required before importing these steel products?

Importers usually request a Mill Test Certificate, a coating weight certificate, and compliance statements such as ISO 1461 for galvanising and ISO 9001 for quality management.

What are the common packaging methods for steel coils from China?

Coils are generally wound on steel drums or placed on wooden pallets, then wrapped in moisture‑resistant film and loaded into 20‑ft or 40‑ft containers for sea freight.

Are there standard quality grades for the Aluminum‑Zinc‑Silicon coated plates?

These plates typically meet EN 14509 or equivalent standards, with alloy composition of 55 % Al, 43.5 % Zn and 1.5 % Si, and are inspected for coating thickness and adhesion.

What certifications should a buyer verify for the corrugated board?

Buyers should look for ISO 12048 strength class certification and, if sustainability is required, FSC or PEFC chain‑of‑custody certification.

What is the usual lead time for a bulk order of hot‑dipped galvanized coils?

Lead times for Chinese manufacturers range from 4 to 8 weeks after order confirmation, depending on coil dimensions, coating specifications and container availability.
