About Shandong Hengze New Material Co., Ltd. - Steel Products Supplier in China

Shandong Hengze New Material Co., Ltd. is based in China and currently lists eight distinct steel‑related products. The catalogue covers galvanized steel coils, galvanized steel sheets, hot‑dipped corrugated roofing sheets, hot‑dipped steel plates, annealed cold‑rolled steel coils, and Aluzinc (galvalume) steel coils. These items fall under the broader categories of steel coils, steel sheets, roofing sheets (including gypsum board), and steel plates as indicated in the supplier’s top categories. All galvanized products are classified under HS chapter 72, specifically HS code 7210.49 or 7210.41, reflecting hot‑dip zinc coating on low‑carbon steel. The cold‑rolled coil is listed under HS code 7209.15, which corresponds to cold‑rolled carbon steel products.

The "Galvanized Steel Coil" and "Hengze Galvanized Steel Coil" are described as hot‑dip galvanized steel with zinc coating ranges from Z80 to Z275 and Z120 to Z275 respectively. The "Galvanized Steel Sheet" specifies zinc coating grades Z80‑Z275, while the "Hot‑dipped Corrugated Steel Roofing Sheet" uses DX51D / SGCC steel grades with zinc coating Z100‑Z350. The "Aluzinc Galvalume Steel Coil" employs an aluminum‑zinc alloy coating of approximately 55 % Al, 43.5 % Zn and 1.5 % Si, identified by HS code 7210.61. The "Annealed Cold Rolled Steel Coil" is supplied as SPCC / DC01 cold‑rolled carbon steel under HS code 7209.15. The "Hot‑dipped Steel Plate" is listed with a generic GI coating under HS code 7210.49. No gypsum board product is detailed with an HS code, but the supplier’s top categories include it.

Product Range and Specialties of Shandong Hengze New Material Co., Ltd.

The catalogue presents six galvanized steel items and two specialty coils. The hot‑dip galvanized coils and sheets (HS 7210.49) are typically produced to ASTM A653/A792 or EN 10346 specifications, with zinc coating weights expressed as Z‑series values that correspond to approximately 80 - 275 g/m². The corrugated roofing sheet (HS 7210.41) follows the DX51D or SGCC steel grade, a common cold‑rolled profile used in roofing and cladding, and is usually supplied with a zinc coating between Z100 and Z350, meeting ASTM A792 or GB/T 4172 standards. The Aluzinc galvalume coil (HS 7210.61) conforms to ASTM A792 and ISO 1461, offering a protective alloy layer that provides superior corrosion resistance compared with pure zinc. The annealed cold‑rolled coil (HS 7209.15) matches SPCC / DC01 grades under JIS G3302 or EN 10130, with typical thicknesses from 0.5 mm to 2.0 mm and tensile strengths around 270 MPa. These industry benchmarks help buyers compare the supplier’s offerings with global quality expectations.

Trade and Export Information - Shandong Hengze New Material Co., Ltd.

China is a major exporter of hot‑dip galvanized and galvalume steel, supplying construction, automotive, appliance and infrastructure sectors in Southeast Asia, the Middle East, Africa and Eastern Europe. HS chapter 72 products such as 7210.49 (galvanized coils, sheets, plates) and 7210.41 (corrugated roofing) are subject to standard customs tariffs and often require importers to present a mill test certificate, conformity to ASTM or EN standards, and proof of ISO 9001 quality‑management systems. Buyers typically request CE marking or equivalent conformity documentation for roofing sheets intended for building applications. Shipping is usually arranged in 20‑ft or 40‑ft containers with coils wrapped in protective paper and placed on wooden pallets; roofing sheets are bundled in cardboard or shrink‑wrapped packs. Common Incoterms are FOB Qingdao or CIF destination port, with freight forwarders handling export customs clearance under Chinese regulations such as the Export Control Law and the mandatory inspection of steel products for quality and safety.

Sourcing from Shandong Hengze New Material Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a Mill Test Certificate (MTC) that details chemical composition, tensile strength, elongation and coating weight for each steel grade. Verify that the zinc coating weight matches the advertised Z‑series range (e.g., Z80‑Z275) and that the Aluzinc alloy composition aligns with the 55‑Al/43.5‑Zn/1.5‑Si specification. Ask for compliance documents such as ASTM A653/A792, EN 10346 or ISO 1461 certificates, and confirm whether the supplier holds ISO 9001 certification; if not, require a third‑party inspection report before shipment. Typical minimum order quantities are 1 ton for coils and 5 tons for sheets, with lead times of 30‑45 days after receipt of a confirmed purchase order and all required test reports.

Check the packaging method: coils should be wrapped in anti‑rust paper and secured on steel or wooden frames, while roofing sheets are usually bundled in moisture‑resistant cardboard. Confirm container loading plans to avoid damage to surface coatings, and request pre‑shipment photos or a pre‑shipment inspection (PSI) report to validate surface condition and dimensions.

What HS codes are used for the galvanized steel products listed by the supplier?

The galvanized coil, sheet and plate items are classified under HS code 7210.49, while the hot‑dipped corrugated roofing sheet uses HS code 7210.41. The Aluzinc (galvalume) coil is listed under HS code 7210.61 and the annealed cold‑rolled coil under HS code 7209.15.

Which industry standards should be checked for the galvanized coils and sheets?

Buyers should verify compliance with ASTM A653/A792 or the European EN 10346 standard, which define zinc coating weight, tensile strength and dimensional tolerances for hot‑dip galvanized steel.

What coating thickness ranges correspond to the Z‑series values mentioned in the catalogue?

A Z80 coating roughly equals 80 g/m² of zinc, Z120 about 120 g/m², and Z275 about 275 g/m². These values translate to approximately 0.8 µm to 2.75 µm of zinc layer thickness.

How can I obtain a mill test certificate for the Aluzinc Galvalume Steel Coil?

Request the supplier to provide an MTC that lists the exact Al‑Zn‑Si alloy percentages, tensile strength (typically 250‑300 MPa), and coating thickness. The certificate should reference ASTM A792 or ISO 1461 compliance.

What are the typical minimum order quantities and lead times for these steel products?

Minimum order quantities are usually around 1 ton for coils and 5 tons for sheets or roofing panels. Lead times commonly range from 30 to 45 days after order confirmation and receipt of required test documents.

How are the hot‑dipped corrugated roofing sheets packaged for export?

Roofing sheets are normally bundled in moisture‑resistant cardboard or shrink‑wrap packs, each bundle labeled with size, weight and HS code 7210.41, and then loaded into a 20‑ft or 40‑ft container on wooden pallets.

Which regions typically import Chinese galvanized and galvalume steel?

Key import markets include Southeast Asian countries (Vietnam, Thailand, Indonesia), the Middle East (UAE, Saudi Arabia), African nations (Kenya, South Africa) and Eastern European states, where the material is used for construction, automotive bodies and appliance manufacturing.

What pre‑shipment inspections are recommended for these steel products?

A pre‑shipment inspection should verify coating weight (using a magnetic gauge), surface visual quality, dimensional compliance, and the presence of the required Mill Test Certificate. The inspection report can be issued by a recognized third‑party agency before the goods are loaded onto the vessel.
