Now that the difference is clear, let’s examine the pros and cons of aluminum versus steel tubing and what makes aluminum the preferred choice for many fabricators.
Choosing Between Aluminum vs Steel Tubing for Fabricators
When selecting materials for lightweight frames, displays, and fixtures, many professionals compare aluminum vs steel tubing. Both materials offer distinct benefits, but aluminum has become the preferred option for fabricators who value ease of handling, corrosion resistance, and cost-effective customization.
Aluminum tubing is significantly lighter than steel, making it easier to transport, cut, and assemble in-house. For companies producing SEG frames, trade show components, or retail displays, that difference in weight translates to real efficiency gains on the production floor and during installation. Unlike steel, aluminum also doesn’t require additional coatings or treatments to prevent rust, which simplifies inventory and long-term maintenance.
Testrite Aluminum offers a variety of aluminum tubing options in raw mill finish or silver anodized, and we provide cut-to-length service to help reduce preparation time for fabricators. However, we do not offer mitering, hole drilling, or frame assembly. Our customers complete those steps as part of their in-house fabrication process.
By comparison, steel tubing is often heavier, more challenging to machine, and prone to corrosion if not correctly treated. It may be better suited for heavy-duty or permanent installations. Still, for lightweight applications where ease of customization is a priority, aluminum offers a superior experience for fabricators and manufacturers.

Why Aluminum Tubing vs Steel Tubing Matters in Lightweight Builds
For companies that fabricate display frames, retail fixtures, or portable structures, choosing between aluminum tubing and steel tubing has implications that extend beyond material cost. It impacts handling, machining, and performance over time.
Aluminum tubing is easier to cut, drill, and transport than other materials. This is especially valuable for fabricators who process large volumes of material and want to avoid the added labor and wear that comes with working steel. When you're fabricating in-house, every added step matters. Aluminum helps streamline that process without sacrificing the clean, professional look expected in customer-facing environments.
At Testrite Aluminum, we supply raw aluminum tubing in a variety of diameters and finishes. Our silver anodized tubing offers a sleek appearance that resists fingerprints and surface wear, making it ideal for visible frame components. These materials are shipped in full lengths or can be cut to length based on your specifications.
While steel tubing has its place in more permanent or industrial applications, it often requires secondary finishing to prevent rust and may be unnecessarily heavy for temporary or mobile structures. You can read more about the advantages of aluminum’s natural resistance to oxidation in our article on why thin-wall aluminum tubing is a smart choice.
In short, aluminum tubing allows manufacturers and display companies to build efficient, lightweight systems while maintaining a professional finish and keeping fabrication in-house.
Comparing Aluminum vs Steel Pipe for Custom Projects
When evaluating material options for custom projects, the difference between aluminum and steel pipe involves more than just appearance. The function, fabrication process, and compatibility with accessories all impact how the material performs in a build, especially when fabrication is handled in-house.
Although “tubing” and “pipe” are sometimes used interchangeably, they are not the same. Pipe is usually specified by its internal diameter and is more often used in plumbing and heavy industrial applications. Tubing, by contrast, is defined by its outer diameter and wall thickness, which makes it better suited for frames, displays, and lightweight enclosures. This is why Testrite Aluminum offers tubing, not pipe.
Steel pipe is heavier and typically requires coatings or galvanization to prevent rust from forming. It also takes more time and effort to machine. Cutting, drilling, and assembly can be more demanding on tools. Aluminum, on the other hand, is easier to cut and drill, and it can be machined using standard shop tools.
For fabricators building displays, SEG frames, or enclosures that don't carry structural building loads, aluminum tubing provides clean finishes, lower weight, and faster processing. It also doesn’t rust. You can learn more in our post on does aluminum rust.
Evaluating Aluminum vs Steel Strength for Frames and Fixtures
Strength is often the first factor engineers and fabricators consider when choosing materials. When comparing the strength of aluminum and steel, it's essential to consider the actual strength required for the end use.
Steel is stronger than aluminum in terms of tensile strength and resistance to deformation. But for lightweight frames, fixtures, and displays, that level of strength is usually more than what’s needed. In fact, using steel in these applications can introduce unnecessary weight and complexity without delivering additional value.
Aluminum has a high strength-to-weight ratio, making it especially useful in applications where weight savings are as significant as durability. For example, an SEG frame made from aluminum extrusion can support graphic panels and hardware effectively without adding excess bulk. This is one reason many manufacturers and display companies choose aluminum over steel for portable and modular systems.
At Testrite Aluminum, our tubing is designed for non-structural applications where visual presentation and ease of assembly are more critical than load-bearing capacity. For teams fabricating their own displays or modular systems, aluminum provides reliable strength while being easier to work with.

Understanding the Weight of Aluminum vs Steel in Fabrication
Aluminum weighs significantly less than steel, making it easier to handle, cut, and install. This can improve efficiency during fabrication and reduce shipping costs.
While steel offers more density, it often adds unnecessary bulk to light-duty frames and displays. For most in-house fabrication needs, aluminum provides the right balance of strength and weight.
Aluminum vs Steel Corrosion Resistance in High-Traffic Environments
Aluminum naturally resists corrosion by forming a protective oxide layer on its surface. Anodized finishes add even more durability, making aluminum ideal for displays and frames used in busy or cleaned environments.
Steel is more prone to rust and usually requires coatings or treatments. Even stainless or galvanized steel can show wear over time. For long-term appearance with minimal maintenance, aluminum is the more practical choice.
Aluminum vs Steel Cost: What Fabricators Need to Know
While steel often costs less per pound, aluminum can reduce overall project costs. It's lighter, easier to machine, and requires less finishing. These advantages translate to lower labor time, faster production, and reduced shipping expenses.
Steel may seem cheaper upfront, but it often requires coatings to prevent rust and more time to fabricate. For teams managing in-house builds, aluminum offers better long-term value.
Testrite Aluminum supplies cut-to-length aluminum tubing in raw or anodized finishes, giving fabricators flexibility without added processing. All fabrication steps, like mitering or drilling, are handled by the customer.
