Fastening Aluminum Soffits


If one was going to use aluminum soffit panels to put a ceiling on a structure (like a carport) with steel I-beams (W section) spaced across the structure, how would one go about attaching the soffit panels to the I-beams?

TIA!

Best to put up a set of purlins that can more easily be screwed into to span the distance across the beams.

This will level the surface as well as give you a nail/screw base.

Attaching soffit to a steel beam is painful to say the least.

And do the purlins need to span the space between beams, or just a short distance across each beam? How would the purlins themselves be fastened to the beams?

You are ultimately going to have to fasten the purlins to the beams.

You should have them span the full length and see if you can use plastic or some sort of pressure treated lumber where it meets the steel.

What kind of spacing should be used for purlins?

typically 16" o.c running perpindicular to the direction of the soffit so you have a constant fastening base to screw the soffit to
