Welcome to Hemaokang Steel (Shandong) Co., Ltd. As an established manufacturer with an annual export value between US$50 Million and US$100 Million, we specialize in producing high-quality structural steel products for global construction needs. Our Structural Galvanized Coil S350GD Z275, with a precise thickness of 2.5mm and a maximum coil weight of 15 tons, is specifically designed for the production of Light Steel Frame (LSF) panels. This coil guarantees exceptional yield strength, outstanding corrosion protection from the Z275 zinc coating, and excellent formability for various roll-forming processes. Whether you are manufacturing wall studs, roof trusses, or floor joists, this structural coil offers the consistency and performance your production line demands.
Key features of our S350GD Galvanized Coil include:
- High Strength Steel Grade: The S350GD designation ensures a minimum yield strength of 350 MPa, providing reliable structural support for light steel frame buildings.
- Z275 Zinc Coating: A uniform hot-dip galvanized layer of 275 g/m² offers decades of protection against rust and environmental corrosion.
- Precise Thickness: The 2.5mm material thickness is maintained within tight tolerances, allowing for accurate bending and punching without cracking.
- Large Coil Capacity: With a maximum coil weight of 15 tons, your production can run longer with fewer coil changes, reducing downtime and material waste.
- Designed for LSF Panels: This coil is optimized for roll-forming into C/Z sections, U profiles, and other LSF panel components.
- Customized Dimensions: We offer adjustable coil widths, inner diameters, and packaging options according to your project requirements.
The table below outlines the main technical specifications of this structural galvanized coil:
| Property | Value |
| Steel Grade | S350GD |
| Coating | Z275 (275 g/m²) |
| Thickness | 2.5 mm |
| Coil Weight | Up to 15 tons |
| Coil Width | Customizable (e.g., 600–1500 mm) |
| Inner Diameter | 508 mm / 610 mm (optional) |
| Surface Finish | Spangled or minimized spangle (optional) |
| Application | Light Steel Frame panels, structural components |
| Quality System | ISO9001 certified |
Our production facility employs advanced cold rolling and hot-dip galvanizing lines to transform raw steel into a highly uniform coil. At each stage, we conduct rigorous tests including thickness gauging, coating weight measurement, and tensile strength verification. This ensures that every coil delivered meets the stringent requirements of structural applications. The S350GD grade provides a high yield-to-tensile ratio, making it ideal for cold forming by roll forming machines. The zinc coating adheres well, and the surface remains suitable for additional processing such as punching, notching, and welding.
The key advantages for your business are clear. First, the longer coil weight of up to 15 tons minimizes production interruptions. Second, the consistent thickness and strength reduce scrap and rework. Third, the Z275 coating extends the service life of the finished LSF panels, reducing complaints and warranty claims. Fourth, the material can be easily cut to length or slit to width to match your machinery. Finally, our direct factory supply means you get short lead times and competitive pricing without sacrificing reliability.
Common applications for this structural galvanized coil include:
- Wall studs and track sections for LSF panels
- Roof trusses and ceiling components
- Floor joists and load-bearing channels
- Purlins in low-rise industrial buildings
- Modular and prefabricated construction systems
We understand that every project has unique requirements. Our coils are available with different widths (commonly from 600mm to 1500mm) and inner diameters (508mm or 610mm). We provide options for standard export packaging, including sea-worthy pallets, steel table packaging, or wooden crates, all with protective wrapping to avoid damage during transit. Additionally, we can supply special edge treatments or spangle-free surfaces upon request. Our engineering team can also provide technical data sheets and mill test certificates for every batch.
Quality is the cornerstone of our company. We are proud to have passed the ISO9001 quality management system certification. Every production process is monitored by an experienced quality team. From raw material procurement to final coil loading, we implement traceability measures that let you know exactly where and how your steel was produced. Our annual export volume of US$50–100 Million proves that we are a trusted partner for customers across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East.

FAQ – Frequently Asked Questions
Q1: What is the minimum order quantity?
A: The MOQ generally depends on the coil weight and container load. Typically, one 20-foot container is required, but we can discuss specific quantities based on your needs.
Q2: Can you provide mill test certificates?
A: Yes, each coil includes a mill test certificate showing the chemical composition and mechanical properties. Third-party inspection is also welcome.
Q3: What width and inner diameter options are available?
A: We offer widths from 600mm to 1500mm, inner diameters of 508mm and 610mm, or custom sizes to suit your roll former specifications.
Q4: How is the coil packaged for shipping?
A: We use standard export packaging: inner rust-proof paper, outer steel sheet wrapping, and steel strapping with edge protection. Pallet or wooden crate options are available.
Q5: What is the delivery time?
A: For regular sizes, delivery is about 15–20 days after deposit. Large orders or customized products may take 25–30 days.
Q6: Can you supply other grades like S250GD or S320GD?
A: Yes, we can produce various structural steel grades upon request. Please specify your required grade and coating weight.
Q7: Is this coil suitable for welding?
A: S350GD is generally weldable with proper welding procedures. We recommend removing the zinc layer at weld points to avoid fume generation and ensure weld quality.
Q8: Do you offer samples?
A: We can provide small sample pieces for quality evaluation. Please contact our sales team with your address and the specifications you need to test.
