Fabrication Tolerances for Dimensional Variance in Aluminum Angle and Machined Parts

Standard Tolerances For Structural Aluminum Angle

What is material thickness tolerance?

A material thickness tolerance is the allowable variation between a material's nominal thickness and its actual measured thickness. Because we work to nominal thicknesses, the material you receive will vary slightly from the figure on the spec sheet.

Why it matters at the design stage

Choosing material thickness is usually one of the first steps a designer takes when starting a project. Proper tolerances ensure that parts fit together seamlessly, which is especially important for assemblies.

Don't forget finish tolerances

Adding a finish such as powder coat increases the overall thickness, and this should be factored into your design from the beginning.
