Steel vs. Aluminum: What’s Best for Your Next Fabrication Project?
Choosing the right metal for your fabrication project is one of the most important decisions you'll make—whether you're designing a custom gate, building a staircase, or fabricating commercial platforms. Two of the most commonly used materials in the industry are steel and aluminum, each with its own strengths and limitations.
As Lexington’s trusted experts in steel fabrication and aluminum welding, ASB Welding Pros is here to guide you through the key differences, helping you make the best decision for your next project.
🔩 Strength and Durability
Steel is known for its superior strength and load-bearing capabilities. It’s often the go-to choice for structural applications like:
If your project demands high durability—such as industrial support structures or heavy-duty security gates—steel fabrication in Lexington, KY is your best bet.
Aluminum, while lighter, isn’t as strong as steel. However, it offers excellent corrosion resistance, making it ideal for projects exposed to moisture, weather, or chemicals—especially in outdoor or marine environments.
⚙️ Weight Considerations
Aluminum is about one-third the weight of steel, which can make it easier to transport, install, and handle. This makes it the better option for:
Lightweight driveway gates or automated gate systems
If weight is a concern—for example, for motorized moving parts or portable equipment—aluminum welding in Kentucky might be the smarter choice.
🌦️ Corrosion Resistance
Aluminum naturally resists rust and corrosion without the need for coating. This makes it ideal for outdoor projects that are constantly exposed to rain, snow, or humid conditions.
Steel, on the other hand, needs additional protective measures like galvanizing or powder coating to prevent rusting. However, when treated properly, steel can also last decades with minimal maintenance.
💰 Cost and Budget
Steel is generally less expensive than aluminum when comparing raw material costs. However, the installation costs (due to weight and labor) can be higher.
Aluminum may come at a higher material cost, but the overall project may be more cost-effective due to lower handling, transportation, and finishing expenses.

🔧 Fabrication and Welding Differences
Both metals require different welding techniques and tools:
Steel is more forgiving and easier to weld, especially for heavy-duty structural work. It's ideal for applications like metal fencing and metal columns or piers.
Aluminum welding requires precision, experience, and specialized equipment—but it results in sleek, lightweight fabrications perfect for residential and decorative use.
