The arch is built from/composed of/ assembled by...

Hi there,

I'm struggling with the following title:

Design and Production of an arch built from lightweight components
Design and Production of an arch composed of lightweight components
Design and Production of an arch assembled by lightweight components
Design and Production of an arch built by means of lightweight components

Any idea which of these are correct?

The first two are correct (although "built of" might be better), the third is not correct, and the fourth is awkward at best. "Constructed of / from" is one alternative.

Thank you!
