Product Description
DX51D+AZ Galvalume Steel Coil with >75% Solar Reflectivity for Building Envelope
Our DX51D+AZ Galvalume Steel Coil is engineered for building envelope systems, combining long-term durability with exceptional energy efficiency. Its core is a hot-dip 55% aluminum-zinc-silicon coating (55% Al, 43.4% Zn, 1.6% Si), which provides 2–6 times better corrosion resistance than standard galvanized steel and a proven service life of 20–25 years. A key advantage is its >75% solar radiant heat reflectivity – nearly double that of galvanized steel – significantly reducing building cooling costs while withstanding temperatures up to 315°C (600°F) without discoloration. Certified to ASTM A792/A792M, this coil delivers reliable, high-performance solutions for demanding architectural applications worldwide.

FAQ
Q: What is the typical lifespan of this product in a building envelope application?
A: Its high solar reflectance (over 75%) means it bounces back a significant portion of the sun's radiant heat. This helps in reducing heat absorption through the building envelope, leading to lower cooling loads and energy savings, especially in hot climates.
Q: What's the payment term for Galvalume Steel Coil?
A: 30-50% TT in advance (based on your qty), 70% balance against copy B/L in 7 workdays.
Q: When will you send BL copy?
A: In 3-5 workdays after shipment date.
Q: When will you send original Documents?
A: In 3-5 workdays when we get the balance.
Q: What is the lead time for samples?
A: Samples are available in 7-10 days after detailed requirements confirmation.
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.
