Frequently Asked Questions
Q1: What is the difference between DX51D and other galvanized steel grades?
A: DX51D is a low-carbon steel grade specifically designed for forming and drawing applications. It offers excellent ductility compared to structural grades like S220GD or S250GD, making it ideal for automotive parts that require complex shapes.
Q2: Can the Z275 coating weight be reduced or increased?
A: Yes, we offer various coating weights such as Z100, Z180, Z275, and Z350. Z275 is a standard choice for automotive applications. Please contact us with your specific requirements.
Q3: What is the maximum width and thickness you can produce?
A: Our standard production range is 0.8–2.5 mm thickness and 600–1500 mm width. For special sizes, please inquire as we may be able to accommodate custom orders.
Q4: Do you provide samples before bulk order?
A: Yes, we can provide free samples (shipping cost borne by customer) for evaluation. Please contact our sales team to arrange sample delivery.
Q5: How long does delivery usually take?
A: For standard specifications, delivery time is typically 15–25 days after deposit. For large orders or custom specifications, please consult our team for an accurate lead time.
Q6: Is the product suitable for exposed automotive body panels?
A: Yes, the DX51D Z275 grade with appropriate surface finish can be used for internal and external automotive parts. For exposed panels, we recommend a spangle-free finish to ensure a smooth painting surface.
Q7: What packaging do you use for export?
A: Each coil is wrapped with waterproof paper, plastic film, and steel bundling straps. Additional protection like wooden crates or VCI paper is available upon request.
Q8: Do you have ISO9001 certification?
A: Yes, our company is ISO9001 certified, ensuring consistent quality management throughout production and delivery.
