20×20 Aluminum Extrusion Dimensions

The dimensions of a standard 20×20 aluminum extrusion are as follows:

• Width: 20 millimeters (mm)
• Height: 20 millimeters (mm)
• Cross-Sectional Area: 400 square millimeters (mm²)

To break this down further:

• Width: The width of the aluminum extrusion is 20 mm, or approximately 0.79 inches.
• Height: The height of the aluminum extrusion is also 20 mm, or approximately 0.79 inches.
• Cross-Sectional Area: The total cross-sectional area of the 20×20 aluminum extrusion is calculated by multiplying the width and height, which results in 400 square millimeters (mm²), or approximately 0.62 square inches.

Benefits and Drawbacks to Using Aluminum Extrusion 20×20

This standardized 20×20 mm square profile is a widely used size in the aluminum extrusion industry, offering a range of benefits, however, everything always has both benefits and drawbacks.

• This simplifies the fabrication and assembly process for various projects.

Potential Drawbacks of Aluminum Extrusion 20×20

Limited Load-Bearing Capacity:

• While strong for its weight, the 20×20 mm size may have limitations in terms of maximum load-bearing capacity compared to larger extrusion sizes.
• For applications requiring higher structural loads, a larger extrusion size may be necessary.

Cost Considerations:

• Aluminum extrusion can be more expensive than other materials, such as steel, especially for smaller quantities.
• The cost may be a factor for budget-constrained projects or applications.

Potential for Deformation:

• Aluminum, while strong, is still susceptible to deformation under high loads or impact forces.
• Proper design, reinforcement, and support may be required in applications with significant stress or loading.

Surface Finish Limitations:

• The extruded surface of 20×20 aluminum may not have the same level of polish or smoothness as other finishing processes, such as machining or casting.
• Specific surface treatments or coatings may be required for certain aesthetic or functional requirements.

Overall, the benefits of 20×20 aluminum extrusion, including its structural integrity, lightweight, and corrosion resistance, often outweigh the potential drawbacks, making it a widely used and versatile solution across various industries and applications.

20×20 Aluminum Extrusion CAD Models
