How do composite panels compare to .125 plate or foam panels?
There are several ways to achieve flatness with metal panels. Foam panels offer insulative value and span capabilities but have significant sizing limitations as well as small quantity set up and production costs. Plate systems offer similar advantages to composite panels but do not offer standard 20 year finish warranties (see above for post finish vs. coil coating); provide less flexibility when field issues arise, and cost more than composite systems.
