Frequently Asked Questions (FAQ)
Q1: What does DX51D+Z stand for?
A: DX51D+Z is a European standard designation for hot-dip galvanized steel. 'DX' indicates steel for cold forming, '51' denotes a minimum yield strength of 140 MPa, 'D' means hot-dip coating, and '+Z' indicates zinc coating. This grade offers excellent formability and weldability.
Q2: What is the difference between regular spangle and zero spangle?
A: Regular spangle has visible zinc crystals on the surface, giving a classic patterned look. Zero spangle (or minimized spangle) has a more uniform matte appearance. Regular spangle is often preferred for applications where appearance is not critical, or for further painting, as it provides good adhesion.
Q3: Can this coil be used for roofing?
A: Yes, 0.5mm thickness with Z275 coating is commonly used for residential and commercial roofing sheets, especially in areas with moderate corrosion risk. The material can be roll-formed into corrugated or trapezoidal profiles.
Q4: What is the typical lead time for this product?
A: For standard sizes (width 1000-1250mm, coil weight 5-8 tons), lead time is usually 15-20 working days after order confirmation. Custom sizes may require 25-30 working days. We recommend contacting our sales team for current stock availability.
Q5: Do you provide material test certificates?
A: Yes, we provide mill test certificates (MTC) in accordance with EN 10204. Tests include chemical composition, tensile properties, coating weight, and surface condition. Third-party inspection is also available upon request.
Q6: How is the coil packaged for export?
A: Our standard export packaging includes: inner plastic film wrapping, waterproof kraft paper, steel strapping with edge protectors, and optional wooden pallet or steel crate for small coils. We also offer custom packaging as per customer requirements.
Q7: Can you supply other thicknesses, such as 0.3mm or 1.0mm?
A: Yes, we offer a wide range of thicknesses from 0.2mm to 2.5mm in hot-dipped galvanized steel. The Z275 coating is available for thicknesses ≥0.5mm. Please inform our sales team of your specific requirements.
Q8: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% balance before shipment), L/C at sight, and other negotiable terms subject to credit evaluation. For long-term partners, we can discuss open account possibilities.
