FAQ
Q1: What is the difference between SGCC and DX51D galvanized steel coil? A1: SGCC is a JIS standard commercial-grade galvanized steel with no fixed mechanical value requirement, while DX51D is a European EN standard grade with clear standardized mechanical properties and stricter process control. Our SGCC DX51D combines the advantages of both standards, featuring stable quality, good formability and wider compatibility for global market demands.
Q2: What zinc coating weights are available for stock? A2: We have regular stock of Z80, Z100, Z180 and Z275 galvanized layers. Custom zinc coating from Z40 to Z275 g/㎡ is acceptable according to customer's usage and anti-corrosion requirements.
Q3: Can you provide customized size and surface treatment? A3: Yes. We support custom thickness, width, coil weight and inner diameter. Multiple surface treatments including oiled, dry, passivated and non-passivated are optional to meet stamping, painting and outdoor usage needs.
Q4: Is the galvanized layer easy to peel or crack during processing? A4: No. Our SGCC DX51D GI coils have excellent zinc layer adhesion. It can withstand 180° bending without peeling or cracking, and is fully suitable for stamping, rolling, welding and other secondary processing.
Q5: What certificates and test reports can you provide? A5: We can provide official Material Test Report (MTR), factory inspection certificate, and support SGS, BV and other third-party authority inspections to meet import customs clearance and customer quality audit requirements.
Q6: What is your MOQ and delivery time? A6: The MOQ is 1 ton for trial orders and 5 tons for bulk orders. Conventional specifications have sufficient stock and can be delivered within 3-7 days; customized products take 7-15 working days according to production schedule.
Q7: What industries is DX51D SGCC galvanized steel coil mainly used for? A7: It is widely used for building roofing and wall panels, home appliance shells, automotive accessories, hardware products, storage shelves, ventilation pipes and various anti-corrosion metal parts, covering most civil and industrial manufacturing fields.
Q8: How to ensure no rust during long-distance transportation? A8: We adopt multi-layer professional packaging with waterproof paper, moisture-proof plastic film and reinforced steel strapping. The sealed packaging effectively isolates moisture and oxidation, ensuring intact product surface during ocean and land transportation.
