Product Introduction
CNB’s Galvalume roofing coils deliver exceptional outdoor durability with an AZ150 (equal to Z275) coating. The aluminum‑rich coating forms a tough oxide barrier that is highly resistant to atmospheric corrosion, making it perfect for exposed roofs, garage doors, and agricultural sheds. Supplied in regular and minimized spangle finishes, our GL coils are easy to roll‑form and cut on standard profiling lines.
