0.27mm AZ50 DX51D Galvalume Corrugated Sheet for Roofing and Outside Wall Panels

１．Product Overview

0.27mm AZ50 DX51D Galvalume Corrugated Sheet is designed for roofing sheets, outside wall panels, building envelope systems, garage doors, window blinds, and industrial construction applications.

The product uses DX51D galvalume steel with 50g/m² AZ coating, regular spangle surface, and passivated treatment. The corrugated sheet form improves panel rigidity and supports practical installation for roofing and exterior wall applications.

２．Technical Solution

The galvalume substrate is coated with an aluminum-zinc alloy layer to improve corrosion resistance compared with uncoated steel. The 50g/m² AZ coating provides surface protection for construction and building panel applications.

Passivated surface treatment helps protect the sheet during storage, transportation, and fabrication. Regular spangle provides a standard metallic appearance suitable for roofing and wall panel systems.
