Benefits of Using 2020 Aluminum Extrusion
Key Advantages
- Lightweight but Strong
- Aluminum’s low density makes it easy to carry, ship, and maneuver, without sacrificing moderate structural strength.
- Corrosion-Resistant
- Aluminum naturally forms a protective oxide layer; anodization further enhances its resistance to moisture and chemicals.
- Modularity & Flexibility
- You can build, disassemble, and reconfigure structures—ideal for evolving projects or rapid prototyping.
- Ease of Integration
- The T-slot system enables fast addition of brackets, hinges, wheels, handles, or panels.
- Professional Appearance
- Engineered finish looks clean, modern, and is easy to keep clean.
- No Welding or Painting Needed
- Cuts labor costs and reduces workplace hazards.
- Cost-Effective for Small Projects
- Lower upfront and assembly costs compared to welded steel, especially for short or changing run sizes.
Common Use-Case Scenarios
- Hobbyists, makers, educators, and small businesses rely on 2020 extrusion for robotics, enclosures, and demos.
- Industrial automation and lab environments use it for rapidly changing setups and custom equipment.
- Solar panel racking and small architectural installations (especially where weight must be minimized).
How to Choose the Right 2020 Extrusion
Key Factors to Consider
-
Project Load Requirements
- Standard 2020 profiles support moderate loads; for heavier structures, consider 20×40/20×60 extrusions or reinforced variants.
- Always check manufacturer’s published load ratings for both static and dynamic loads.
-
Profile Type & Shape
- Straight-edge for typical structures.
- Rounded-edge (RQ) for safe-touch corners or visible furniture.
-
Length & Custom Cutting
- Available in pre-cut lengths (commonly 300mm–2m) or can be custom ordered for exact sizing.
- Consider machine shop options for precision cutting, drilling, and tapping ends.
-
Slot Width Compatibility
- Standard 2020 extrusions use a 6–6.2mm T-slot. Confirm that your chosen accessories (nuts, bolts, plates) are compatible.
-
Surface Finish & Color
- Most profiles are clear anodized for durability and aesthetics.
- Some suppliers offer black anodized or powder-coated (colored) options if appearance is critical.
-
Accessory Ecosystem
- Check for the availability and pricing of connectors, feet, panels, fasteners, and custom accessories.
-
Budget
- Prices vary by supplier, finish, and customization—balance upfront cost, installation time, and re-usability.
-
Lead Time & Local Availability
- Common sizes are often in stock, but special finishes or custom cuts may add time.
Practical Tips & Best Practices
Design & Planning
- Mock up your structure digitally (CAD software or online configurators) to optimize material use and reduce waste.
- Always account for connector space when calculating panel and brace lengths—T-slot connectors typically use 10–20mm of slot.
- Reinforce key load points with additional brackets or heavier profiles.
Cutting & Assembly
- If cutting extrusions yourself, use a miter saw with a carbide blade designed for aluminum; deburr edges for clean assembly.
- Consider having ends tapped (threaded) by professionals if bolting directly into ends of the bar is planned.
Connection & Fastening
- For the strongest joints, use T-nuts with hex-head bolts. For heavy or high-vibration structures, sliding nuts provide even stronger connections.
- Align slots carefully before tightening—framework “square” ensures strength and appearance.
Safety & Maintenance
- Wear gloves when handling raw extrusions; cut ends can be sharp.
- Regularly check and retighten bolts if the structure is subject to vibration.
- Clean with mild detergent—avoid abrasive scrubs, which can mar anodized surfaces.

User Tips: Getting the Most from 2020 Extrusion
- Plan for Expansion: Design your structure with standardized hole patterns or extra length if you anticipate future modifications.
- Choose Connector Types Wisely: Inside corner brackets are concealed but can reduce internal slot use; outside brackets are stronger for high-load corners.
- Don’t Over-Torque Fasteners: Aluminum is softer than steel—tighten to specification to avoid damaging threads or slots.
- For Furniture: Add rubber feet or plastic end-caps for stability and a finished look.
- For Electronics: Ground the frame if static or EMI shielding is a concern.

FAQ
What is 2020 aluminum extrusion?
2020 aluminum extrusion is a modular, T-slotted profile measuring 20mm x 20mm in cross-section. Made from high-strength aluminum alloy and anodized for durability, it’s used to build frames, enclosures, automation equipment, and more.
What are the main differences between standard 2020 and 2020 RQ profiles?
The standard 2020 has sharp, straight corners and slightly higher load-bearing capacity. The 2020 RQ features gently rounded corners, making it safer to handle and suitable for exposed edges or furniture, but it supports slightly lighter loads.
How strong is 2020 extruded aluminum?
It offers moderate strength—ideal for light to medium structures. Tensile strength is commonly in the 150–215MPa range. For heavy equipment or large spans, a larger profile (like 2040, 4040, or 8020) should be used.
What sizes and lengths are available?
2020 extrusions are available in pre-cut lengths from around 300mm to 2,000mm (30cm–2m), or custom cut to your specifications. Most suppliers offer cutting, drilling, and tapping as needed.
What fasteners and accessories do I need?
You usually need M6 (or sometimes M5) T-nuts, hex head bolts, corner brackets, and end caps. Specialized connectors (for hinges, wheels, or joining at angles) are also widely available.
Can I connect 2020 extrusion profiles without welding?
Yes, 2020 extrusions are designed to be assembled entirely with bolts, T-nuts, and brackets—eliminating the need for welding or specialized fabrication.
Is 2020 aluminum extrusion rustproof?
Yes, aluminum is naturally resistant to rust and corrosion. Anodized surfaces further increase resistance, making it suitable for humid or mildly corrosive environments.
Can I mix and match components from different brands?
Most 2020 profiles adhere to international standards (such as the European 20 Series), so T-nuts, brackets, and accessories are often interchangeable across makes—check specifications to ensure fit.
Does 2020 extrusion require special tools to cut or drill?
For small projects, a standard miter saw (with an aluminum-rated blade) can cut profiles. Drilling and tapping can be done with woodworking or DIY metalworking tools, but for precision and larger batches, consider professional machining services.
Can I paint or further finish 2020 aluminum extrusion?
Yes, but most 2020 extrusions already feature an anodized (protective) finish. Painting is possible if needed; use aluminum-specific primers and paints. Powder-coating is another option, often available from suppliers as a custom service.
This comprehensive guide equips you to confidently select, plan, and build with 2020 aluminum extrusion—unlocking the potential for robust, reconfigurable, and visually appealing creations in any field.
