Decorative Metal Samples: Include the Visible Edge in Appearance Approval

The key distinction

Edges may have a different finishing history or geometry from the main face. They can also be harder to access consistently during preparation and application. The goal is not to assume that every edge needs the same treatment, but to decide what is included and how the completed assembly should be inspected.

Practical checks

1. Obtain a sample that represents the final face and relevant edge condition.
2. Identify any functional exclusions or bonding areas before the treatment trial.
3. Inspect the approved trial from normal viewing angles and record whether the edge result matches the agreed appearance and work scope.

Example

Illustrative example: a large decorative panel is approved using a flat offcut, but its visible folded return has a different finish. The offcut did not answer the edge-appearance question. A representative formed sample would have made that limitation clear before the project was scaled.

Scope and limits

Do not coat mating faces, fasteners or functional interfaces simply to make coverage appear complete. Confirm the actual assembly requirements. Appearance approval on a sample should state which surfaces and geometries it represents rather than implying blanket approval for every component detail.
