2020 aluminum extrusion is a modular 20mm × 20mm T-slot structural profile, typically manufactured from 6063-T5 aluminum alloy. Its precision-machined slot geometry enables rapid bolt-together assembly without welding, making it the preferred framing solution for CNC machines, 3D printers, automated workstations, industrial enclosures, and custom fabrication projects. Linsy supplies 2020 aluminum extrusion profiles with clear or black anodized finish, custom cut-to-length, CNC machining, and full accessory support — with MTC reports available on every order.

2020 aluminum extrusion is a 20mm × 20mm T-slot structural aluminum profile designed for modular frame assembly without welding. The number “2020” denotes its nominal cross-section: 20mm wide by 20mm high. Each face of the profile features a standard T-slot groove, typically 6mm or 6.2mm wide on the slot opening and 10-12mm wide at the inner channel, designed to accept standard T-nuts, bolts, and connecting hardware.
2020 profiles are most commonly extruded from 6063-T5 aluminum alloy, which offers a good balance of strength, surface finish, and extrudability. The T-slot geometry transforms aluminum extrusion from a simple structural shape into a modular building system — frames can be assembled, modified, and reused without drilling, welding, or permanent fasteners.
As one of the most popular T-slot profile sizes, 2020 is widely used for desktop CNC routers, 3D printer frames, laboratory test stands, industrial workbenches, safety guarding, and custom retail displays. Compared with larger T-slot series (3030, 4040, 4545), 2020 profiles are lighter, more economical, and ideally suited for light-to medium-duty framing where compact dimensions and fast assembly are priorities.
Linsy supplies 2020 aluminum extrusion profiles in standard and custom lengths. All profiles are manufactured from 6063-T5 alloy and available with multiple surface finish options.

2020 T-slot aluminum extrusion profiles are designed to work with a standardized ecosystem of connecting hardware. Linsy can supply compatible M4/M5 T-nuts, bolts, brackets, and connectors alongside your extrusion order — eliminating the need to source accessories from multiple suppliers.
Common compatible hardware includes:
If you need a complete hardware kit for your frame assembly project, please include the list of required components with your inquiry.
2020 profiles are widely used for constructing machine frames, conveyor supports, sensor mounting rails, and safety guarding in automated production lines. Their modular nature allows quick reconfiguration when production layouts change.
The 2020 T-slot and V-slot profile is the structural backbone for most desktop 3D printers (including popular open-source designs), CO2 laser engravers, and small-format CNC routers. Its light weight, sufficient rigidity for desktop machines, and compatibility with standard linear rails make it the default choice for the maker and small-manufacturing community.
Research labs and test facilities use 2020 aluminum profile to build custom test stands, camera mounting rigs, sensor arrays, and cleanroom fixtures. The anodized surface resists chemical exposure, and the modular design supports rapid modification as experiment requirements evolve.
2020 T-slot profiles are used for modern retail display racks, exhibition booth frames, point-of-sale fixtures, and industrial-style furniture. The clean anodized finish and precise corner connections deliver a professional, high-tech appearance suitable for branded retail environments.

For 2020 aluminum extrusion specifically, Linsy offers:
Q: What is the difference between 2020 T-slot and 2020 V-slot aluminum extrusion?
A: Standard 2020 T-slot has a rectangular groove designed for T-nuts and standard connecting hardware. 2020 V-slot adds a V-shaped bevel to the outer edge of the slot, designed to guide V-groove wheels for linear motion systems used in 3D printers and CNC routers. If your project involves moving gantries or carriages, V-slot is the better choice.
Q: What is the maximum span for an unsupported 2020 aluminum extrusion beam?
A: The safe span depends on the load, mounting configuration, and acceptable deflection. As a general guideline, an unsupported 2020 profile with a distributed load of 5 kg can typically span up to 500 mm with less than 1 mm deflection. For longer spans or heavier loads, consider increasing the profile size (e.g., 2040 or 4040 series) or adding intermediate supports. Linsy can provide deflection calculations for your specific application on request.
Q: Can 2020 aluminum extrusion be cut and drilled by the customer?
A: Yes. 2020 aluminum profiles can be cut with a carbide-tipped chop saw or bandsaw, and drilled with standard HSS drill bits. However, the anodized surface is harder than raw aluminum, so cobalt or carbide tooling will extend tool life for high-volume cutting. For precision CNC drilling and tapping, Linsy recommends using coolant to prevent chip welding.
Q: Is 2020 aluminum extrusion corrosion-resistant?
A: Yes. 6063-T5 aluminum alloy has good corrosion resistance in atmospheric environments, and the anodized surface finish provides an additional protective oxide layer. For indoor applications, both clear and black anodized finishes offer excellent long-term corrosion protection. For outdoor applications, powder coating or a thicker anodizing film (20 μm or above) is recommended.
Q: What is the weight of 2020 aluminum extrusion per meter?
A: A standard 2020 T-slot profile in 6063-T5 alloy weighs approximately 0.5 kg per meter. The exact weight varies slightly depending on the internal web geometry and any additional grooves (e.g., V-slot).
Q: Can I order 2020 extrusion with a different alloy grade?
A: Standard 2020 profiles are supplied in 6063-T5. If your application requires higher strength (e.g., 6061-T6, 6082-T6) or different properties, please contact Linsy to discuss custom extrusion feasibility and minimum order quantities.
Q: Does Linsy supply pre-assembled frames or finished products?
A: Linsy primarily supplies 2020 aluminum extrusion profiles and compatible hardware. We can provide pre-cut and pre-drilled profile kits with labeled components for your assembly team. Full frame assembly services may be available for volume orders — please discuss your requirements with our sales team.
Q: What is the minimum order quantity (MOQ) for 2020 aluminum extrusion?
A: Linsy supports low-MOQ orders. Standard stock lengths are available from single-piece quantities. Custom cut-to-length orders may have a small minimum order value. Contact us with your specific requirements for a quotation.
Q: What is the lead time for 2020 aluminum extrusion orders?
A: Standard stock lengths typically ship within 2–7 days. Custom cut-to-length, CNC processing, or custom anodizing orders typically ship within 10–60 days depending on order complexity and volume.
Q: Do you ship internationally?
A: Yes. Linsy ships aluminum extrusion products to Europe, North America, Southeast Asia, the Middle East, and other regions. Shipping methods (air freight, sea freight, express courier) and costs are quoted based on order weight, dimensions, and destination.
Q: Can I get a sample before placing a bulk order?
A: Yes. Sample lengths of 2020 aluminum extrusion are available for evaluation. Sample cost and shipping terms will be quoted based on the quantity and destination. Contact Linsy to request a sample.
Q: What payment methods does Linsy accept?
A: Common payment methods include T/T bank transfer and letter of credit (L/C). Specific payment terms are agreed during order confirmation and may vary by order value and customer history.
