Corner Trim should be selected according to the actual wall or roof corner detail rather than only by its appearance. The required leg dimensions, return edges, material, thickness and coating can affect how well the trim covers the joint and how easily it can be installed. For sandwich panel buildings, accurate corner dimensions also help maintain a clean external finish while reducing exposed panel edges.

How do I know what Corner Trim size I need?
The required size depends mainly on the panel thickness and the corner detail. Providing the panel specification and a drawing or corner dimension allows the correct trim size to be selected.
