DX51D Galvalume Steel Coil For Construction
Product Description

Our Skin-Passed DX51D Galvalume Steel Coil delivers superior formability and enhanced corrosion resistance for construction applications. Featuring a hot-dip 55% Al-Zn coating (AZ100-AZ275), it provides 2-4 times longer service life than standard galvanized steel. The skin-passing process ensures a smooth, spangle-minimized surface for excellent paint adhesion and eliminates stretcher strains during fabrication. Compliant with ASTM A792/A792M, it is an ideal choice for structural and architectural projects.

FAQ

Q: How do you control quality?
A: Mill Test Certification is supplied with shipment, Third Party Inspection is available.


Q: Why is skin-passing important?
A: Skin-passing (or temper rolling) improves surface flatness, controls yield point elongation to prevent stretcher strains during forming, and provides a superior surface for painting.


Q: Can you provide sample?
A: Small samples in store and can provide the samples for free.Customized samples will take about 5-7days.


Q:What is your working time?

A: Our online service time is Beijing time: 8:00-22:00. After 22:00, we will reply to your inquiry in the coming working day.
