Description

Applications of the WPC Internal Corner Trim (35×35)

The internal corner profile is designed for clean and accurate joins at inside corners. It enhances visual consistency, reduces visible gaps, and helps prevent dust and dirt buildup in interior or semi-open spaces finished with WPC.

• Inside corner finishing in façades or ceilings
  Covers and beautifies areas where two surfaces meet at an internal 90° angle (e.g., wall-to-ceiling or wall-to-floor joints).
• Framing and clean detailing of internal angles
  Creates a neat, professional frame in internal corners to improve visual unity.
• Reinforced 90-degree joint between two WPC surfaces
  Strengthens the inner-angle connection without requiring precise angle cuts, while maintaining structural integrity.
• Internal corner framing for stairs or walls
  Especially useful where WPC is used on stair details or inside wall corners, completing the look with a uniform finish.
• Fast finishing where miter cutting is difficult on site
  When miter cutting is not practical during installation, this profile provides a quick and effective finishing solution.
• Hides rough, cut, or uneven edges
  Covers unfinished or irregular cut edges inside corners for a clean, professional appearance.

Benefits of the WPC Internal Corner Trim

  Suitable for residential, villa, landscaping, and decorative projects—both indoor and outdoor.

Surface Finishes for WPC

WPC surfaces can be supplied with several finish options, including Embossed, Brushed, and Sanded Embossed finishes.
Among these, Sanded Embossed—a combination of embossing and sanding—offers the closest look and feel to natural wood and is one of the most popular choices.

WPC can also be used in its raw form (without surface finishing).

Note: Surface finishes are only applicable to smooth surfaces, including:

• Embossed
• Sanded Embossed
• Brushed
