A Clean Finish for Exterior Corners

The Composite Outside Corner Trim 90° External Corner is designed to finish the point where composite cladding panels meet across two exterior walls. Its 90° external-corner profile connects, covers, and protects panel edges while creating a clean, secure, and seamless transition.

Co-Extruded WPC Construction

Made from co-extruded Wood Plastic Composite (WPC), this exterior finishing trim is waterproof, moisture resistant, UV resistant, and weather resistant. Its durable, low-maintenance construction makes it a practical finishing component for exterior composite cladding systems.

Profile and Color Options

Each trim is exactly 107 inches long and has an external-corner profile measuring 1.42 inches × 1.42 inches. The lower measured profile section is 1.1 inches.

Available color options include Gray, Brown, Dark Brown, and Black, allowing the trim to coordinate with a range of exterior cladding designs.

Residential and Commercial Applications

This trim is suitable for house walls, building facades, exterior feature walls, entryways, commercial buildings, offices, restaurants, hospitality properties, retail buildings, multifamily properties, and exterior renovation projects. It provides a finished appearance while helping cover and protect exposed cladding edges at outside corners.

Planning Your Cladding Finish

Use this profile specifically where exterior composite cladding meets at a 90° outside corner. Before use, confirm that the 107-inch length, 1.42-inch × 1.42-inch corner profile, and 1.1-inch lower measured section are appropriate for the cladding system and project layout.
