== Calculating load capacity and deflection ==
Formulas depend on the type of fastening of the aluminium profile:<ref>{{Cite web |title=Aluminium profile load capacity {{!}} Blog - Tuli experience |url=https://www.tuli-shop.com/blog/aluminium-profile-load-capacity.html |access-date=2023-09-26 |website=www.tuli-shop.com}}</ref>

where:
* <math>\sigma [\frac{N}{mm^2}]</math> is the bending tension
* <math>F [N]</math> is the [[force]] or load
* <math>L [mm]</math> is the free profile length
* <math>W [mm^3]</math> is the moment of resistance
* <math>I [mm^4]</math> is the moment of [[inertia]]
* <math>f [mm]</math> is the deflection
* <math>E [\frac{N}{mm^2}]</math> is the [[Elastic modulus|elasticity module]]
* <math>K [\frac{N}{mm^2}]</math> is the max. bending tension with values:
