90° Outside Corner Aluminum Flashing – Closed Hem – 10′ is fabricated from .040″ aluminum with ½″ closed hems on both edges for added strength, safety, and a clean, finished appearance. Designed for use at exterior wall corners, this flashing provides a crisp, protective transition while preventing moisture intrusion at exposed edges.

Each piece is painted on one side to create a smooth, uniform finish on visible surfaces. Available finishes include Mill Finish, Black Onyx, Bone White, and Silver. The hemmed edges protect against sharp edges and help the material maintain rigidity during installation and handling.

This flashing is available in multiple outside corner dimensions:

• 1″ × 2″
• 1½″ × 2″
• 2″ × 2″
• 2½″ × 2″
