製品の説明
Heat Reflective Galvalume Steel Coil For Building Envelope
Our Heat Reflective Galvalume Steel Coil is engineered specifically for building envelope systems that demand long-term durability and energy efficiency. The core of this product is a hot-dip 55% aluminum-zinc-silicon coating (55% Al, 43.4% Zn, 1.6% Si). This unique composition provides 2-6 times better corrosion resistance compared to standard galvanized steel, offering a proven service life of 20-25 years in normal environments.
A key feature is its exceptional heat reflectivity - it reflects over 75% of solar radiant heat, which is nearly double the reflectivity of standard galvanized steel. This superior reflectivity can significantly reduce cooling costs for buildings. The coil also withstands high temperatures up to 315°C (600°F) without discoloration, making it ideal for sun-exposed building surfaces. Certified to ASTM A792/A792M, it delivers reliable performance for demanding architectural applications worldwide.

Frequently Asked Questions
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.
