0.22mm AZ35 DX53D Galvalume Steel Coil for Industrial Roofing and Building Panels
0.22mm AZ35 DX53D Galvalume Steel Coil for Industrial Roofing and Building Panels
１．Product Overview
0.22mm AZ35 DX53D Galvalume Steel Coil is a hot dipped aluminum-zinc coated steel product used for roofing panels, exterior wall panels, industrial buildings, refrigeration equipment, and general construction applications.
The product uses DX53D substrate with 35g/m² AZ coating and passivated surface treatment. The galvalume coating provides corrosion resistance and surface protection for building and industrial applications, while the regular spangle surface gives a typical metallic appearance.
２．Technical Solution
The steel substrate is coated with an aluminum-zinc alloy layer through a hot dipped galvalume process. The AZ coating helps improve resistance to atmospheric corrosion and supports use in roofing, wall cladding, and industrial sheet applications.
The passivated surface treatment improves temporary surface protection during storage, transportation, and fabrication. Regular spangle provides a standard visible coating pattern suitable for industrial and construction panels.
