How to calculate the amount of double angle aluminum extrusions you need
If you're not sure how much double angle extrusion you need for your case, the formula is simple:
Add the lengths of all four edges of the case (left, right, front, back) and multiply by 2 to get the perimeter.
Example: (40 + 40 + 20 + 20) × 2 = 240
Multiply the height of the case (top to bottom) by 4.
Example: 20 × 4 = 80
Add the two results together, then divide by 12 to get the total feet required.
Example: (240 + 80) ÷ 12 = 27 feet
For a cleaner, more professional look without any seams at the edges, it's better to calculate each required length carefully and buy enough extrusion for all parts.
As always, we recommend ordering a little extra to account for cutting errors or unexpected adjustments during assembly. It's better to have a little leftover than to run short in the middle of your project.

Related questions about double angle aluminum extrusions
How do I connect double angle extrusions under oblique angles?
Double angle extrusions are primarily designed for 90-degree connections. For oblique or non-standard angles, you can miter cut the profiles at the required angle using a saw, then join them with rivets or brackets to maintain strength.
What rivets are needed for installation?
The size and quantity of rivets depend on the length of the extrusion and connected parts.
Most rivets are installed through the inner leg of the extrusion, so backing washers are usually not required unless your design specifies otherwise.
Are there any cutting tutorials available for easier installation?
Yes, we provide simple cutting tutorials to guide you through precise measuring, marking, and sawing techniques. Always use proper tools such as a miter saw or aluminum cutting blade for clean, accurate cuts.
Can I place a small order?
Yes, we support small batch orders to help you test the market or start new projects.
What payment methods do you accept?
We accept T/T (bank transfer), L/C, PayPal, Western Union, and other secure payment methods.
