Hemaokang Steel (Shandong) Co., Ltd. proudly introduces our top-grade Galvanized Steel Coil — a reliable and versatile product designed for demanding industrial applications. As an export-focused manufacturer based in Liaocheng, Shandong, we combine advanced production technology with strict quality control to deliver steel coils that meet international standards. Our coils are carefully packed on pallets with waterproof paper to ensure they arrive in pristine condition, and every order is backed by a 1-year official warranty for your complete peace of mind.
Whether you are in construction, manufacturing, or infrastructure development, our galvanized steel coil offers outstanding corrosion resistance, excellent formability, and long service life. It is an ideal choice for roofing, wall cladding, cold-formed steel structures, and many other applications. We understand that consistency matters — so each coil is produced under ISO9001 quality management systems and rigorously tested to ensure uniform coating, precise thickness, and reliable performance.
Product Features & Specifications
- Superior Corrosion Resistance: The hot-dipped zinc coating provides a protective barrier that resists rust and oxidation, even in harsh environmental conditions.
- Excellent Formability: The steel substrate is made from high-quality low-carbon steel, allowing easy cutting, bending, stamping, and roll-forming without cracking.
- Consistent Coating Thickness: Our advanced galvanizing line ensures uniform coating weight across the entire width, minimizing the risk of bare spots or uneven protection.
- Smooth Surface Finish: Available in regular spangle, minimized spangle, and zero spangle finishes, catering to different aesthetic and functional requirements.
- Custom Sizes: Thickness ranges from 0.12mm to 4.0mm, and width from 600mm to 1500mm — we can customize dimensions to match your specific production needs.
- Secure Packaging: Each coil is protected with waterproof paper and palletized with steel strapping, preventing damage during transit and long-term storage.
- Reliable Warranty: Every shipment is covered by a 1-year warranty, guaranteeing our commitment to product quality and after-sales support.

Frequently Asked Questions (FAQ)
1. What is the lead time for export orders?
For standard sizes, production takes approximately 1-2 weeks after deposit, depending on order quantity. Urgent orders can be arranged with priority production planning upon your request.
2. How is the coil packed to prevent rust during shipping?
Each coil is wrapped in waterproof paper, placed on a pallet, and secured with steel straps. For extra protection, we can also use vapor-phase anti-rust oil or vacuum packing as optional protections.
3. Can I get small quantities for a test order?
Yes, small trial orders are welcome. We keep stock of common specifications like 0.35mm, 0.5mm, and 0.8mm thickness to offer fast shipment for test samples, usually within 3-5 days.
4. What is the difference between Z40 and Z275 coating?
Z40 means 40 g/m² of zinc per square meter on one side? Actually coating mass is measured as total zinc on both sides. Z275 means 275 g/m², which offers much higher corrosion resistance and a longer lifespan, ideal for harsh environments or exposed roofing.
5. Do you provide mill test certificates?
Yes, a mill test certificate (MTC) is issued for each production batch. We can also provide inspection reports from third-party agencies like SGS, BV, or TUV upon request at extra cost.
6. Can the coil be produced with custom width or thickness?
Yes, our production line allows customization within the range of 0.12-4.0mm thickness and 600-1500mm width. Please discuss your exact requirements before ordering so we can confirm feasibility and pricing.
7. What is your warranty and after-sales policy?
We provide a 1-year official warranty against material and manufacturing defects. If any quality issue is verified due to our production, we will replace the defective coil or offer a reasonable credit for future orders.
8. Which payment methods do you accept?
We accept T/T (wire transfer), L/C at sight, and D/P. Flexible payment terms are negotiable for long-term cooperation or large contract values.
