6-2040

6-2040 is a light-duty rectangular cross-section in our stock aluminum profile range: 20x40mm, European standard 6-series slot width, 6063-T5 alloy, wall thickness 1.8mm, weight 0.80kg/m. Compared with the square 6-2020, 6-2040 offers stronger bending resistance in the 40mm direction, with a moment of inertia reaching 3.80cm⁴, more than three times that of 6-2020, making it suitable as a column or one-way load-bearing beam for light-duty structures.

All four faces of the profile carry standard 6mm-wide slots, compatible with mainstream 6-series connectors, nuts, angle brackets and other accessories on the market. The 20x40mm rectangular cross-section minimizes material usage while ensuring structural strength, making it an ideal choice for columns and one-way beams in light-duty frames.

01 Raw Materials and Material

Produced from A00 primary aluminum ingot with no scrap aluminum, the material is pure and the structure dense. 6063-T5 aluminum alloy has excellent extrusion formability and surface finishing, and is the standard material for light-duty aluminum profiles.

02 Rectangular Cross-Section Design and Standard Slots

20x40mm rectangular cross-section with stronger bending resistance in the 40mm direction. All four faces carry 6mm standard slots, compatible with all 6-series standard connectors on the market, requiring no custom connectors and enabling high assembly efficiency.

03 Convenient Machining and Assembly

The profile is standard stock, available for immediate order and shipment, with cutting to length on demand. Cutting accuracy is ±0.5mm. Customers can build frames using standard 6-series accessories upon receipt.

04 Stock Inventory, Fast Delivery

6-2040 is a regularly stocked product that ships immediately upon order. Standard length is 6.02m, and any length can be cut. Door-to-door delivery is available within Shanghai.

FAQ (Frequently Asked Questions)

Q1: What is the difference between 6-2040 and 6-2020?

A: They share the same alloy (both 6063-T5) and slot width (both 6-series); the difference is cross-section dimensions. 6-2020 is a 20x20mm square, while 6-2040 is a 20x40mm rectangle. 6-2040 offers more than three times the bending resistance of 6-2020 in the 40mm direction, making it suitable for columns or one-way beams. Choose 6-2020 for lightweight small frames, and 6-2040 when one-way load bearing is needed.

Q2: Is 6-2040 suitable for conveyor line main frames?

A: No. 6-2040 is a light-duty aluminum profile, only suitable for auxiliary structures such as columns, supports and guards in light-duty structures. For conveyor line main frames, we recommend 8-4040 or larger specifications.

Q3: What is the maximum weight 6-2040 can bear?

A: When used as a column, the recommended vertical load per piece is no more than 80kg. Its bending resistance in the 40mm direction is better than 6-2020, but it is not recommended for heavy-load scenarios. For exact data, please provide drawings for our engineering department to evaluate.

Q4: Are 6-2040 accessories interchangeable with 6-2020?

A: Fully interchangeable. Both belong to the 6-series with 6mm slot width, so all connectors, nuts, angle brackets, end caps and other accessories are interchangeable.

Q5: Can 6-2040 be custom cut to non-standard lengths?

A: Yes. Standard length is 6.02m; note the required length when ordering, and we provide precision cutting at ±0.5mm.
