Yes, exterior compact HPL can be curved during installation, but only within a limit set by its thickness. Thin panels can be bent cold and fixed to a curved substructure. Two published manufacturer guides set the limit for 6 mm panels at 2,000 mm and 2,500 mm.

Rounded corners and curved walls are a common request from architects. The curve succeeds or fails at the design stage, long before a panel reaches the scaffold. This guide covers the methods, the limits, the substructure, the site sequence and the tests to run first.

One caution applies throughout. Limits published by one manufacturer describe that manufacturer’s product, so they do not transfer automatically to another panel.
