Understanding the pros and the cons of steel skid plates
If you love off-roading, then you know that rocks, hills, and other obstacles can cause havoc on the underside of your vehicle. That’s why you need to make sure that your off-road ride is equipped with the proper skid plate. When it comes to durability most drivers prefer a steel skid plate. However, is steel the right material for your skid plate? Here, we will take a look at the unique features as well as the pros and cons of steel skid plates. Also, we will take a look at how steep skid plates compare with popular aluminum skid plates.
What is a Steel Skid Plate?
A steel skid plate is a protective piece of equipment that is placed on the underside of your car, truck, or SUV. This plate acts as a layer of protection for your critical vehicle parts and components including the engine and fuel tank. When properly installed, a steel skid plate should be able to protect your vehicle from rock, debris and other obstacles.
Steel skid plates are constructed from high-grade steel which is very resistant to heavy impacts. That’s why so many off-road enthusiasts perfect steel for their skid plates. Over time, a steel skid plate should remain resistant to corrosion and rust.
Key Features of Steel Skid Plates:
● Material: High-strength steel, often treated or coated for rust resistance.
● Function: Protects the vehicle’s undercarriage from damage.
● Durability: High-quality steel skid plates can last for at least five years.
How Thick Should Steel Skid Plates Be?
It is important to consider the thickness of the steel skid plate. The right size of thickness will depend on a couple of factors. Usually, you will be looking at a thickness between 3/16 inch and ¼ inch. The right thickness level will depend on the type of vehicle you drive as well as the type of terrain you will encounter.
Light Off-Roading: If you are looking to traverse over dirt or hilly terrain, you will want to consider the thinner 3/16 thickness level. This will allow your vehicle to save weight and protect your undercarriage from damage.
Heavy Off-Roading: If you anticipate that you will be taking your vehicle over steep grades and large, jagged rocks, then you will want to consider ¼ inch thick steel skid plates. While the plate will be heavier, it will have the durability to withstand high-impact events.
Considerations for Thickness:
● Vehicle Weight: Heavier vehicles should consider thicker steel plates to better protect the underside of the vehicle.
● Terrain Type: The rougher the terrain, the thicker the skid plate should be.
What is the Difference Between a Steel and Aluminum Skid Plate?
When you start shopping for skid plates you will encounter two common choices or materials: steel and aluminum. So let’s take a look at the unique features and capabilities of each material.
Steel Skid Plates:
● Strength: Steel is stronger than aluminum. Therefore, this material will be better able to handle high impacts.
● Durability: Steel skid plates will last longer. With the proper maintenance, a coated steel skid plate should last at least five years.
● Weight: Steel is going to be heavier than aluminum. This means that it will add weight to the vehicle and adversely affect fuel efficiency.
● Rust Resistance: Steel can be susceptible to rust when exposed to road salt, seawater, and other road elements. However, a coated steel skid plate will be more resistant to such corrosion.
Aluminum Skid Plates:
● Weight: Aluminum skid plates weigh less than steel. This offers a number of benefits over steel including lighter weight and better fuel efficiency. Also, it can lead to performance driving.
● Corrosion Resistance: Unlike steel, aluminum is naturally resistant to corrosion. Therefore, there is no need for coating and no need to worry about rusting in rainy or wet environments.
● Strength: While aluminum is not as strong as steel, it does provide ample protection in most driving conditions.
● Cost: Aluminum skid plates are usually a little more expensive than steel. However, aluminum is considered to be a superior material due to its lighter weight and corrosion resistance.
Summary
Steel: Stronger, more durable, heavier, and more affordable.
Aluminum: Lighter, more corrosion-resistant, less impact-resistant, and more expensive.
Why is a Steel Skid Plate Cheaper than Aluminum?
There are several reasons why steel skid plates are cheaper than steel. Here’s a look at the top three reasons why the material is more affordable than aluminum:
Material Cost
Steel is cheaper because iron - which steel is made from - is more abundant. Therefore, the overall cost is going to be lower versus other materials such as aluminum.
Manufacturing Process
Steel skid plates are less expensive to manufacture. That’s because there are more machines available to make steel skid plates.
Durability vs. Cost
While steel skid plates do rust, they are considered an acceptable trade-off due to their lower price.
Our Verdict: Aluminum Skid Plates Offer Many Advantages Versus Steel Skid Plates
While we think steel skid plates are fine, if you are looking for better protection, lasting durability, and higher fuel efficiency, then aluminum skid plates are going to be the smart choice. While aluminum skid plates, you don’t have to worry about rust or corrosion. Also, the durability of aluminum is enough to handle most off-roading terrains.

Frequently Asked Questions
Will a steel skid plate rust?
Yes, steel skid plates can rust when exposed to wet environments over time. However, steel skid plates can be protected with a layer of protective coating.
Can I install a steel skid plate on my vehicle myself?
Yes, while it is possible to install steel skid plates yourself, it is recommended that you have someone assist you due to the heavy weight of the material.
How often should I inspect my steel skid plate?
We recommend that you check your skid plate after each off-roading session. This is to make sure there were no impacts that caused any damage to the plate.
Is the added weight of a steel skid plate significant?
The added weight of the skid plate can be noticeable on lighter vehicles. Some of the adverse effects can include lower driving performance and higher fuel consumption.
Are there alternatives to steel and aluminum skid plates?
Yes, the third most popular material option is UHMW (Ultra-High Molecular Weight) plastic. This material is durable but less popular due to the higher costs of the material.
