As an experienced manufacturer and exporter, Hemaokang Steel (Shandong) Co., Ltd. is proud to supply a high-performance Zinc Coated Galvanized Coil 40g/m2 G60 SPCC Grade 0.25mm for precision stamping. This product has been developed for stamping companies that require predictable material behavior, clean edges and consistent part geometry. With global export experience and an annual export value of 50–100 million US dollars, we are committed to delivering steel coils that match the expectations of modern processing lines.
The coil is produced from selected SPCC cold-rolled steel, a grade widely used in automotive and electrical stamping because of its well-balanced strength and formability. A continuous hot-dip galvanizing process applies a uniform zinc coating of 40 g/m2, which is recognized under the G60 coating class. The relatively thin base material of 0.25 mm offers flexibility for intricate stamping, bending and drawing while still providing enough rigidity for structural small parts.
| Parameter | Value |
| Base Material | SPCC cold-rolled steel |
| Coating Type | Hot-dip zinc coated |
| Coating Weight | 40 g/m2 (G60) |
| Thickness | 0.25 mm |
| Width | Customizable, typical 1000–1250 mm |
| Coil Inner Diameter | 508 mm/610 mm, optional |
| Surface Finish | Spangle / zero spangle / skin pass, optional |
| Edge Condition | Trimmed or slit edge |
| Application | Precision stamping, forming, deep drawing |
- Stable Thickness Control – At 0.25 mm nominal thickness, the coil is produced under a controlled rolling process to minimize thickness variation. This stability helps stamping tools maintain constant pressure, reducing the risk of burrs, cracks and inconsistent bending angles.
- Good Surface Consistency – The strip surface is kept clean and smooth so that sensitive stamping dies are less affected by foreign particles, scratches or oxide residue. A cleaner surface contributes to longer die life and better product appearance.
- Uniform Zinc Layer – The hot-dip galvanizing process provides a dense coating on both sides of the steel. Such uniform coverage helps prevent localized corrosion and gives the stamped parts a consistent level of protection without interfering with the stamping operation.
- Excellent Formability – The SPCC base metal offers predictable elongation and bending behavior, which is important when constructing multi-step progressive dies. It supports sharp bending, flanging, and moderate deep drawing without edge cracking.
- Controlled Hardness – The material hardness is regulated to a suitable range, avoiding excessive hardening that may cause die wear, while also avoiding material that is too soft and leads to poor flatness or stretch marks.
- Flat Strip Profile – With proper tension leveling and slitting, the coil provides good strip shape and minimal edge wave. This makes feeding into high-speed stamping presses smoother and keeps dimensional accuracy high.
Quality assurance is embedded in every stage of production. Our manufacturing facility operates under an ISO9001 certified quality management system, from incoming material inspection to final loading supervision. The coating weight, thickness, width, surface quality and mechanical properties of each coil are regularly checked and recorded. Certificates and test reports are available upon request so that customers can verify the product before shipment. We also offer optional surface treatments such as chromate passivation, light oiling, or dry lubricant coating to match different handling, storage and forming conditions.
- Precision stamped electrical and electronic components, such as terminals and connectors
- Small automotive hardware, brackets, mounting plates and reinforcement parts
- Household appliance components, including motor laminations and support frames

Our export process is designed around the needs of stamping plants that require stable delivery performance. The product can be supplied in slit widths to match your die layout, and coils are carefully packed with moisture-proof paper, plastic film, steel pallets and edge protection angles to prevent transit damage. Shipment is made through Qingdao Port, which provides efficient container handling and reliable ocean freight to major destinations worldwide. Whether you are purchasing for a short production run or a long-term framework, our team is ready to align delivery schedules with your production plan.
Hemaokang Steel (Shandong) Co., Ltd. was established in 2025, yet we have already built a robust export operation with an annual export value of US$50–100 million. Our company employs a dedicated team of 51–100 experienced professionals, covering sales, production coordination and quality inspection. We serve a broad range of international markets, including North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions. By combining ISO9001 management practices with responsive customer service, we aim to become a reliable steel partner for precision stamping manufacturers.

Q: What does SPCC grade mean for galvanized coil?
A: SPCC is a common designation for cold-rolled carbon steel sheet used in general stamping and forming. By galvanizing this base steel, we combine the good formability of cold-rolled steel with a protective zinc layer, making it a practical choice for stamped parts that face mild environmental exposure. -
Q: Is 40 g/m2 zinc coating suitable for outdoor applications?
A: The 40 g/m2 coating is generally intended for indoor, semi-exposed or subsequently painted applications where corrosion demand is moderate. If outdoor service with higher corrosion resistance is needed, please contact us for other coating weight options. -
Q: Can you provide narrow width coils for stamping lines?
A: Yes, we can slit the coils into narrow widths according to your exact strip layout. The typical range is 1000–1250 mm as parent coils, but custom slit widths are available upon request. -
Q: Do you offer surface finishes such as zero spangle or skin pass?
A: Different surface profiles are available depending on the application. Options include regular spangle, minimized spangle, zero spangle and skin-passed finish. Let us know your forming and appearance requirements so we can recommend a suitable surface treatment. -
Q: How do you guarantee material consistency for high-speed stamping?
A: Consistency comes from controlled base material selection, tight process monitoring, and final inspection under ISO9001 procedures. We can provide mill test certificates and dimensional reports to support your incoming quality verification. -
Q: What is the minimum order quantity for a trial order?
A: Trial orders are welcome. We keep certain standard specifications in stock, and smaller volumes are often possible. For a detailed MOQ, please share your required width, coating, surface finish and destination. -
Q: What packaging do you use for export?
A: Our standard export packaging includes moisture-proof paper, plastic film, steel pallets or wooden supports, plus protective edge materials. Packaging can also be adjusted to special handling conditions or delivery routes. -
Q: Can I get a quotation before sending a formal order?
A: Of course. Simply send your specification such as thickness, width, coil weight, coating weight and delivery port. Our export sales team will provide an accurate quotation and delivery advice in a timely manner.
