Will your aluminium profile hold the weight?
Pick a profile, tell us the span and the weight, and see instantly how much it will sag — with a clear recommendation. No engineering degree required.

1 Your set-up
Profile
Mounting orientation
This profile is square — it's equally strong in both orientations.
Unsupported length (span)

Not sure? Just use kilograms — we convert to Newtons for you.
2 How is the weight applied?
F = Force · L = Length (mm) · D = Deflection (mm)
