Luyuan Galvalume-Stahlcoil S350GD/AZ150, 0,21–0,50 mm
Zuverlässiges Galvalume-Stahlband mit einer Z121–Z180-Beschichtung, einer Dicke von 0,21–0,50 mm, mehreren Güteoptionen und anpassbarer Länge für Fertigungs- und Verarbeitungsanwendungen.
Galvanized and Galvalume steel coils are the backbone of modern construction and manufacturing, offering an exceptional balance of structural strength and environmental protection. Through a continuous hot-dip process, the cold-rolled steel substrate is coated with a protective layer—either pure zinc (GI) or an aluminum-zinc alloy (GL)—which acts as a sacrificial barrier against rust and corrosion.
At Luyuan Steel, we supply coils tailored to your exact industrial requirements, from ultra-thin 0.12mm roofing materials to robust 4.0mm structural grades. Our coils are certified to international standards (ASTM, EN, JIS) and are ready for further processing, roll-forming, or immediate application.

Whether you choose our Z275 heavily galvanized coils or our AZ150 galvalume coils, our products provide a reliable, long-lasting barrier against moisture and oxidation, extending the lifespan of your end products.
We cater to diverse industrial needs by offering an extensive thickness range from ultra-thin 0.12mm up to heavy-duty 4.0mm, with widths customizable up to 1,500mm to minimize your material waste during processing.
We offer complete control over the aesthetic and functional finish of your steel. Choose from regular, minimized, or zero spangle, along with surface treatments like Anti-Fingerprint (AFP) to enhance handling and secondary coating adhesion.
Beyond standard commercial quality (DX51D/SGCC), we supply high-tensile structural grades (such as G550 and S350GD) specifically engineered for load-bearing applications like roofing purlins and steel framing.
Every coil is produced under ISO 9001 standards and undergoes rigorous testing for coating adhesion, thickness tolerance (±5% or better), and mechanical properties. Full Mill Test Certificates (MTC) are provided.
Every manufacturing process requires specific material properties. We offer comprehensive customization for your GI and GL coil orders:
| Dimensions | Custom slitting for narrow widths; precise thickness tolerances |
| Beschichtungsgewicht | Specified Z-coating or AZ-coating to match environmental demands |
| Spangle & Surface | Zero spangle for painting; AFP treatment for appliance manufacturing |
| Coil Weight & ID | Custom coil weights and 508mm/610mm inner diameters to fit your decoiler |
| Processing Services | Slitting, cutting to length, and protective packaging |
Galvanized steel (GI) is highly cost-effective and provides excellent protection for most standard construction and indoor applications. Galvalume (GL), with its aluminum-zinc coating, offers superior heat reflectivity and up to 6 times the corrosion resistance of GI in harsh, highly corrosive, or coastal environments.
Spangle bezeichnet die sichtbare kristalline Struktur auf der Zinkoberfläche. Regular Spangle ist Standard und kosteneffizient. Minimized Spangle weist ein feineres, weniger sichtbares Muster auf. Zero Spangle ist vollkommen glatt und damit die ideale Wahl für Anwendungen, bei denen der Stahl lackiert wird oder ein makelloses Oberflächenbild erforderlich ist.
AFP ist eine spezielle transparente Beschichtung, die auf die verzinkte oder Galvalume-Oberfläche aufgetragen wird. Sie verhindert Fingerabdrücke bei der Handhabung, verbessert die Beständigkeit gegen Schwarzrost und bietet eine ausgezeichnete, grundierungsähnliche Oberfläche für die anschließende Lackierung oder Anwendung von Klebstoffen.
