80/20 Inc. 15 Series: Best Overall Ecosystem

The 15 Series from 80/20 Inc. acts as the industry standard for van conversions. Its 1.5-inch profile offers the ideal strength-to-weight ratio for heavy-duty applications like garage storage platforms, bed frames, and primary kitchen cabinets. Because it is the most widely supported system, the sheer variety of brackets, gussets, and hardware ensures that no corner of a van remains inaccessible.

When choosing a long-term build, compatibility is king. Investing in the 15 Series guarantees that if a design change occurs mid-build, the necessary connector is always available from a secondary supplier. While it is not the lightest option, the peace of mind provided by its load-bearing capacity makes it the go-to for serious, full-time rigs.

Choose this system if durability and modularity are the highest priorities. It is the gold standard for those who want to build once and never worry about structural fatigue or hardware shortages. If weight is a secondary concern compared to the need for a bulletproof interior, look no further.

Tnutz 15 Series: The Best Value Alternative

Tnutz offers a high-quality alternative that is functionally identical to the 80/20 15 Series but often arrives at a more competitive price point. For builders working on a tighter budget who refuse to sacrifice structural integrity, this is a top-tier choice. The extrusion quality remains consistent, and the slots are perfectly compatible with standard 15-series hardware.

Budgeting for a conversion often reveals hidden costs that can derail a project. Tnutz allows for the purchase of essential components without the premium markups associated with larger corporate branding. By saving on the framing material, funds can be reallocated to critical components like lithium batteries or high-end appliances.

This brand is recommended for the pragmatic builder who values performance over labels. It performs exactly as expected in demanding road conditions, provided the hardware is torqued correctly. Opt for Tnutz when the goal is a high-strength build that respects the total project bottom line.

80/20 Inc. 10 Series: Best for Upper Cabinets

The 10 Series utilizes a 1-inch profile, making it significantly lighter and more compact than its 1.5-inch counterparts. This makes it the clear winner for upper cabinets, spice racks, or lightweight shelving units where heavy-duty support is unnecessary. It provides the same modular benefits as the larger series without the bulk that eats into precious living space.

Weight distribution is a constant struggle in van builds, especially as the center of gravity rises with overhead storage. Using 10 Series extrusions reduces the static load on the van’s walls and ceiling while still providing enough rigidity for gear. It prevents the interior from feeling cramped while maintaining a clean, industrial aesthetic.

This is the right choice for secondary storage projects or minimalist interior designs. It is not intended for heavy framing or platforms where significant body weight will be applied. For those looking to maximize overhead space without compromising on security, the 10 Series is an essential tool.

FramingTech 40mm: Best Metric Profile Option

Metric extrusions, like the 40mm standard from FramingTech, are the norm outside of North America and offer a high level of precision for builders accustomed to the metric system. The 40mm size sits comfortably between the 10 and 15 series in strength. It is exceptionally rigid and ideal for those integrating European-sourced components or specific van appliances.

Building with metric profiles can simplify the layout process if the design software is already set to millimeters. The components are robust and often feature a slightly different slot geometry that provides a very tight, secure fit. This creates a rattle-free build, which is a major advantage for vehicles that spend significant time on gravel roads or washboard terrain.

Select FramingTech if the build plan favors metric dimensions or requires specific compatibility with international hardware. It is a specialized choice that caters to those who prioritize precision and global component accessibility. If the project design is strictly metric-based, avoid the headache of unit conversion and stick with this high-performance system.

Faztek Black Anodized: Best for a Sleek Look

For many, a van interior should look as polished as a modern apartment. Faztek provides high-quality aluminum extrusions with a factory-applied black anodized finish, eliminating the need for painting or powder coating. This provides a clean, matte appearance that hides scuffs and integrates seamlessly into a modern, high-end design.

Aesthetics often take a backseat to utility, but a well-finished interior increases the overall enjoyment of the space. The black finish offers a sophisticated contrast against wood paneling or white surfaces. Because the anodization is integral to the metal, it is far more durable than spray paint and will not flake over time with vibration.

Choose Faztek if the interior design concept demands a high-end, stealthy, or modern aesthetic. It is a premium product, but the time saved by skipping the finishing process is well worth the investment. If the goal is a professional, turnkey look without the DIY paint-job hassle, this is the definitive choice.

Extrusion-Nuts.com: Best for Fast Sourcing

When a build is mid-swing and a specific bolt or bracket runs short, project momentum can grind to a halt. Extrusion-Nuts.com specializes in rapid fulfillment of the small, essential hardware that keeps T-slot systems together. They excel in providing the granular parts that larger distributors often ship slowly or list as out-of-stock.

Having a reliable source for hardware prevents the common frustration of waiting weeks for a two-dollar component. Their inventory is organized specifically for builders, making it easy to find everything from drop-in T-nuts to specialized corner fasteners. Reliable sourcing is just as important as the quality of the aluminum itself.

This resource is best for the builder who values project continuity and needs a partner for rapid, accurate shipping. It is not a manufacturer, but rather a vital logistics hub for the DIY community. Keep this source bookmarked as the primary insurance policy against hardware shortages during the build process.

How to Choose Your Profile: 10 vs. 15 Series

Deciding between 10 Series (1-inch) and 15 Series (1.5-inch) comes down to the intended load. The 15 Series is meant for the “skeleton” of the build: floors, bed frames, and heavy kitchen blocks that need to withstand high-impact vibrations. The 10 Series is reserved for the “skin” or secondary structures like cabinets, trim, and lightweight dividers.

Misunderstanding this distinction often leads to overbuilding, which adds unnecessary weight and expense. A common misconception is that bigger is always safer. However, adding too much mass to a vehicle increases fuel consumption and strains the suspension. Carefully analyze whether a shelf will hold a light set of clothes or a heavy water tank before selecting the profile.

Always err on the side of the 15 Series for any structure that anchors to the floor or the wall’s primary studs. Save the 10 Series for features that are mounted to other pieces of furniture. By mapping out the weight of each module, you can create a hybrid design that is both lightweight and structurally sound.

Essential Connectors and Fasteners Explained

The strength of an aluminum extrusion build relies entirely on the connectors. Standard brackets and gussets are the most common, but internal fasteners are often superior for a clean look. Drop-in T-nuts are essential for quick assembly, while slide-in nuts provide better structural retention once tightened.

Bolts should always be paired with washers to distribute pressure across the bracket surface. For critical connections, using a thread-locking compound prevents the hardware from vibrating loose while driving. Vibration is the enemy of any mobile build, so every bolt must be tightened to the correct specification to prevent fatigue.

Consider using hidden corner connectors for internal framing where you do not want to see external brackets. These require tapping the ends of the extrusions, which adds time to the build but produces a much more refined result. Select the fastener type based on whether you prioritize ease of assembly or visual cleanliness.

Anchoring Shelving to Your Van’s Structure

Aluminum extrusion is only as secure as the point where it attaches to the van. Never screw shelving directly into thin sheet metal body panels. Always anchor the frame to the van’s factory structural ribs or a secondary wooden framing system installed during the insulation phase.

Use heavy-duty steel L-brackets to bridge the gap between the extrusion and the wall studs. Ensure that there is a slight buffer, such as rubber or felt, between the metal bracket and the van’s body to mitigate squeaks and noise. If the attachment point feels loose or vibrates significantly during a test drive, reinforce it immediately.

Stability is non-negotiable when driving on uneven surfaces. If a shelf is tall, anchor it at both the top and the bottom to prevent the lever effect from pulling the fasteners out of the wall. Proper anchoring ensures that the weight of the contents stays contained even during emergency stops or off-road excursions.

Tools You Need for Cutting and Assembly

Cutting aluminum extrusion accurately requires a miter saw equipped with a non-ferrous metal blade. A standard wood-cutting blade will catch and bind, leading to dangerous kickback and jagged edges. Always use cutting fluid or a light lubricant to keep the blade cool and ensure a smooth, precise finish that allows for flush-fit connections.

In addition to the saw, a set of high-quality hex keys or a torque-limiting driver is mandatory. Consistent torque across all fasteners ensures that the load is distributed evenly across the frame. Keep a file or deburring tool on hand to smooth the edges of every cut, as raw aluminum leaves sharp, dangerous burrs.

Invest in a digital angle finder to ensure that every corner is perfectly square. Even a one-degree error in a frame can cause major alignment issues when installing cabinet doors or drawers. With the right tools, T-slot assembly becomes a clean, efficient process that leaves little room for error.

Building with aluminum extrusion is arguably the most efficient way to achieve a professional, modular, and long-lasting van interior. By selecting the right series for your specific load requirements and utilizing the correct fasteners, you build a space that truly stands the test of the road. Success lies in the planning, so take the time to map your structure before making the first cut.
