A Clean Finish for Exterior Corners

The Composite Outside Corner Trim 90° External Corner provides a neat transition where composite cladding panels meet at a 90-degree outside corner. Its external-corner profile connects and covers the adjoining panel edges, helping protect them while creating a clean, secure, and seamless finish across exterior wall surfaces.

Co-Extruded Composite Construction

Made from co-extruded Wood Plastic Composite (WPC), this finishing trim is designed for demanding exterior environments. The composite construction is waterproof, moisture resistant, UV resistant, weather resistant, durable, and low maintenance, making it a practical complement to exterior composite cladding systems.

Precisely Sized Corner Profile

Each trim measures 107 inches long and weighs 6 lb per piece. The external-corner profile measures 1.42 inches × 1.42 inches, while the lower measured profile section is 1.1 inches. Before installation, confirm that the profile and dimensions are appropriate for the composite cladding system and project layout.

Color Options for Exterior Designs

Available colors include Gray, Brown, Dark Brown, and Black. These options make it possible to select a trim color suited to the surrounding cladding and overall exterior design.

Residential and Commercial Applications

This corner trim is suitable for exterior applications on house walls, building facades, exterior feature walls, and entryways. It can also be used in commercial buildings, offices, restaurants, hospitality properties, retail buildings, multifamily properties, and exterior renovation projects where composite cladding meets at an outside corner.
