Metal trim has become an essential finishing material in modern interiors—especially for wall panels, decorative boards, PVC/WPC wall cladding, and commercial installations. Whether you are designing a hotel lobby, residential feature wall, or retail storefront, metal trims provide clean edges, structural protection, and a premium aesthetic.
This guide covers the most popular types of metal trim for wall panels, installation recommendations, and current design trends to help you choose the right solution for your project.
1. What Is Wall Panel Metal Trim?
Wall panel metal trim refers to aluminum or stainless steel profiles used to:
- Cover exposed panel edges
- Create decorative joint lines
- Protect corners from impact
- Add lighting or visual accents
- Achieve clean transitions between materials
Metal trims enhance both the function and appearance of wall panels, making them a preferred choice in modern architectural design.

3. Material Comparison: Aluminum vs. Stainless Steel
