AZ150 Hot Dipped Galvalume Steel Coil 0.40mm × 1250mm for Roofing and Heat Exchanger Applications

１．Product Overview

AZ150 hot dipped galvalume steel coil combines the corrosion resistance of aluminum with the sacrificial protection of zinc. Manufactured with a 55% aluminum-zinc alloy coating, the product is widely used in roofing systems, wall cladding, heat exchangers, agricultural buildings, ventilation equipment, and industrial fabrication.

The 0.40mm thickness and 1250mm width specification is commonly used for roll forming, roofing sheet production, and insulated building panel manufacturing. The AZ150 coating provides enhanced durability compared with conventional galvanized steel in many atmospheric environments.

２．Technical Solution

The steel substrate is continuously coated with an aluminum-zinc alloy layer through a hot-dip process. The aluminum component provides barrier protection, while zinc offers sacrificial corrosion protection at cut edges and exposed areas.

AZ150 coating weight helps improve resistance to oxidation, moisture, and outdoor weather exposure. The regular spangle surface provides a traditional metallic appearance suitable for construction and industrial applications.

The material supports further fabrication including profiling, bending, roll forming, and cutting operations.

３．Specifications

４．Application

The product is widely used in roofing sheets, wall panels, garages, warehouses, modular buildings, sound barriers, ventilation systems, agricultural facilities, silos, pipelines, greenhouse equipment, heat exchangers, and industrial building structures.

It is also suitable for appliance panels, air conditioning components, electrical cabinets, refrigerator back panels, and general fabrication requiring corrosion-resistant coated steel.

５．Processing

The coil can be processed through slitting, cut-to-length production, roll forming, bending, profiling, punching, and stamping.

Edge protectors, steel straps, and export packing help maintain coil condition during storage and international transportation.

Customized cutting and slitting services can be supplied according to project requirements.
