1.2mm AZ150 Hot Dipped Galvalume Steel Coil for Air Conditioner Panels and Appliance Housing Applications

1.Product Overview

Hot dipped galvalume steel coil is commonly used for appliance panels, enclosure parts, and air conditioner housings where corrosion resistance, heat reflectivity, and forming stability are important. Compared with conventional GI material, the Al-Zn coating system provides a different protective structure, which is often selected for products exposed to humid service conditions or temperature fluctuation.

For this application, 1.2 mm thickness is suitable for rigid panel parts and housing structures, while AZ150 is commonly used when a balanced combination of durability and processability is required.

2.Technical Solution

Product performance is based on:

• Hot dip Al-Zn coating with controlled AZ coating weight
• Aluminum providing heat resistance and reflective performance
• Zinc supporting sacrificial protection at cut edges
• Cold rolled base improving panel flatness and forming consistency
• Surface treatment selected according to storage and downstream handling requirements

In appliance fabrication, panel rigidity, edge stability, and corrosion behavior around punched or bent areas are practical concerns. This is why thickness, coating level, and surface condition need to be considered together rather than separately.

4.Application

• Air conditioner outer panels and internal housings
• Refrigerator back panels and appliance sheet parts
• Electrical cabinets and light industrial enclosures
• Ventilation panels and fabricated covers
• Roofing and wall sheet for light construction use
• General cut-to-length and formed sheet applications

5.Processing

• Cut-to-length sheet production
• Slitting into narrower strips
• Bending and folding
• Punching and panel forming
• Surface coating or painting if required
• Assembly for appliance and enclosure components

6.Advantages

• AZ coating improves corrosion resistance in appliance service environments
• 1.2 mm thickness provides better panel rigidity for housing parts
• Al-Zn surface offers good thermal reflectivity for heat-related equipment
• 914–1250 mm width range fits common appliance and panel processing lines
• Passivated, oiled, and anti-finger options support storage and downstream handling
• Coil supply improves efficiency for continuous sheet fabrication

7.How to Choose

• Air conditioner housings with higher rigidity requirement → 1.0–1.2 mm is commonly selected
• More demanding corrosion environment → higher coating such as AZ100–AZ180 is usually preferred
• Longer storage before forming → passivated or oiled surface is commonly selected
• Cleaner handling before assembly → anti-finger surface can be considered
• Continuous production line → confirm width, coil ID, and coil weight with equipment capacity

8.FAQ

Q1: Is this product galvanized steel coil or galvalume steel coil?
This specification is galvalume steel coil, using an aluminum-zinc coating rather than a pure zinc coating.

Q2: Why is AZ150 often used for appliance housings?
Because it provides a practical balance between corrosion resistance, processing stability, and material cost.

Q3: Is 1.2 mm suitable for air conditioner panels?
Yes, 1.2 mm is commonly used when better stiffness and panel stability are needed.

Q4: Can this coil be processed into sheets for appliance fabrication?
Yes, it can be cut to length or slit into narrower strips according to downstream production requirements.

Q5: What surface treatment is suitable before storage and forming?
Passivated, oiled, or anti-finger surface can be selected depending on storage period, handling condition, and later processing needs.
