DX53D AZ180 Galvalume Steel Coil 0.69mm Thickness Aluzinc Steel Coil for Building Materials and Appliances

１．Product Overview

DX53D AZ180 Galvalume Steel Coil is an aluminum-zinc coated steel product designed for applications requiring enhanced corrosion resistance and long-term durability. Combining the barrier protection of aluminum with the sacrificial protection of zinc, Galvalume steel offers superior service life compared with conventional galvanized steel in many atmospheric environments.

The product is widely used in building materials, household appliances, automotive components, machinery, and industrial manufacturing.

２．Technical Solution

The steel substrate is coated with an aluminum-zinc alloy layer through a continuous hot-dip process. The coating structure provides excellent protection against corrosion while maintaining good formability and surface quality.

The material is available with passivated, chromated, oiled, non-oiled, and skin-passed surface conditions to meet different fabrication and end-use requirements.

３．Specifications

４．Application

The product is suitable for roofing systems, wall cladding, steel structure buildings, household appliance panels, automotive components, machinery enclosures, shipbuilding applications, environmental engineering projects, and industrial equipment manufacturing.

５．Processing

Galvalume steel coils can be processed through slitting, cut-to-length production, roll forming, stamping, bending, profiling, and color coating lines.

The material maintains good surface quality and dimensional consistency during fabrication.
