What Kind of Metal is a Washing Machine Cabinet?

A washing machine cabinet is typically made from various types of metal, including steel, stainless steel, aluminum, and even galvanized metal in some cases. The specific metal used depends on the washing machine model and manufacturer, but steel and stainless steel are the most common.

Why Metal is Used for Washing Machine Cabinets

There are several reasons why metal makes a good material for washing machine cabinets:

Durability

Metal is very durable and can withstand the vibrations, moisture, and daily wear-and-tear of a washing machine. Steel and stainless steel, in particular, are strong and corrosion-resistant. This allows the cabinet to maintain its structural integrity for many years.

Noise Reduction

The dense properties of metal help block sound and vibration from the internal components of the washing machine. This allows for a quieter operation compared to cabinets made from plastic or other lighter materials.

Rust Resistance

Stainless steel contains chromium that forms an invisible passive layer protecting it from corrosion and rust. This prevents unattractive rust stains from forming on the cabinet over time in humid laundry rooms.

Appearance

Metal has a sleek, modern look desired by many appliance manufacturers and consumers. Steel and stainless steel provide an attractive, durable finish.

Heat Resistance

During the wash cycles, the interior of a washer can get quite hot. Metal stands up well to high temperatures without warping, deforming, or degrading over time.

Common Metals Used for Washing Machine Cabinets

Now let’s look at some of the specific metals commonly used to construct washing machine cabinets:

Steel

Regular carbon steel is a very common and affordable choice for washer cabinets. It offers good durability and corrosion resistance when coated with enamel, zinc, or other finishes. Steel allows for a variety of color finishes.

Stainless Steel

Stainless steel is rust and corrosion-resistant, as well as very durable. It maintains its shiny, chrome-like finish for years. Stainless steel provides an attractive look and is easy to clean. It is more expensive than regular steel.

Aluminum

Aluminum is a lightweight but strong metal. It resists corrosion and is easy to shape. Aluminum allows manufacturers to make cabinets with sleek, sculpted designs. It also keeps the overall weight of the appliance down. The soft finish scratches easily.

Galvanized Steel

Galvanized steel has a protective zinc coating applied to prevent rust and corrosion. It offers a good balance of strength and affordability. The galvanized coating gives the metal a dull gray finish.

Construction of a Washer Cabinet

A washer’s metal cabinet contains multiple parts riveted and welded together:

• Outer wrapper – The visible exterior walls are made from coated sheet metal. This forms the sides, top, front and back panels.
• Inner tub – The inner wash tub is made of stainless steel, aluminum or enameled steel. It holds the spinning agitator and cleans the clothes.
• Base frame – A powder-coated steel base frame securely holds all components together.
• Backsplash – A curved metal backsplash mounts behind the tub to shield the wall from splashes.
• Door glass – A tempered glass window set into a plastic or metal frame allows viewing inside.
• Top cover – A coated steel or plastic lid gives access to the water hoses, pumps and motors.
• Access panels – Removable panels on the lower back and sides allow servicing of internal parts.

Pros and Cons of Common Washer Cabinet Metals

| Type of Metal | Pros | Cons |
|-|-|-|
| Steel | Affordable, strong, scratch-resistant finish | Prone to rusting without coating, dents show easily |
| Stainless Steel | Very durable, resists corrosion, attractive finish | More expensive, can be scratched over time |
| Aluminum | Lightweight, resists corrosion, easy to shape | More expensive, finish scratches easily |
| Galvanized Steel | Low cost, zinc coating resists rust | Coating can peel over time, dull gray look |

Protecting a Metal Washer Cabinet

To keep a steel or aluminum washing machine cabinet looking its best and prevent corrosion, it is important to:

• Wipe up any spills or moisture after washing cycles.
• Avoid using abrasive cleaners that could scratch the finish.
• For stainless steel, apply a stainless steel cleaner/polish monthly.
• Use touch-up paint on any scratches to prevent rust.
• Make sure the laundry room has adequate ventilation to minimize moisture buildup.
• Place a rubber mat under the washer to prevent floor scratches and vibration.

Key Takeaways:

• The most common metals used for washing machine cabinets are steel, stainless steel, aluminum and galvanized steel.
• Metal provides durability, noise reduction, rust resistance, appearance, and heat tolerance.
• Stainless steel offers the best corrosion resistance and attractive look but at a higher cost.
• Proper cleaning and care is required to maintain the finish and prevent scratches or rust on metal washer cabinets.
• The cabinet is constructed from multiple formed metal parts welded and riveted together to create the outer wrapper, tub, frame and access panels.

So in summary, steel and stainless steel are the most common metals used for modern washing machine cabinets, providing an optimal balance of strength, appearance and cost. With proper care, a quality metal cabinet will last for many years of dependable service.

Frequently Asked Questions About Washing Machine Cabinet Metals

Q: What is the strongest metal for a washing machine cabinet?

A: Stainless steel is the strongest and most durable metal used in washer cabinets. The chromium in stainless steel resists rust and corrosion better than other metals.

Q: Are stainless steel washing machines better?

A: Stainless steel washing machines are more durable and corrosion-resistant than those with regular steel or aluminum cabinets. They maintain their attractive finish for longer. The main downside is the higher price tag.

Q: Why are some washing machine cabinets plastic?

A: Some lower-end washing machines have plastic cabinets instead of metal. Plastic is cheaper but not as durable or resistant to higher wash temperatures. Plastic cabinets tend to be noisier as well.

Q: How thick is washing machine sheet metal?

A: The sheet metal used for washer cabinet panels is typically 0.5mm to 1mm thick. High-quality stainless steel or aluminum may be a bit thicker for added dent resistance.

Q: Should washing machine cabinets be sealed?

A: Manufacturers typically apply a protective sealant or powder coating to new washing machine cabinets. Reapplying a clear sealant annually can help maintain the finish. Avoid sealing over rust areas.

Q: How do you repair rust spots on a washer cabinet?

A: Light rust spots can be sanded down with fine grit sandpaper and touched up with appliance enamel paint. Heavier rust may require filling pits with auto body filler before painting. Prevent further rust by sealing and ventilating.

Conclusion

In summary, steel and stainless steel are the most optimal metals for washing machine cabinets due to their strength, corrosion resistance, and attractive appearance. While plastic and aluminum are sometimes used, most quality washing machines have durable metal cabinets. With proper maintenance and care, a metal washer cabinet should provide many years of dependable service. Be sure to wipe up moisture, use gentle cleaners, touch up scratches, and keep the laundry room well-ventilated.
