50x50mm WPC Decking Corner Trim - Outside Corner Profile

This WPC (wood-plastic composite) corner trim measures 50mm x 50mm in cross-section and is used to finish the outer corners of decking and cladding, covering cut board edges and giving a clean, closed corner line. It is part of the HS decking accessory range and matches the appearance of the composite boards.

Key Specifications

Why Choose This Fastener

• Covers cut board ends for a clean, closed external corner
• Matches the woodgrain appearance of the deck boards
• Rot, termite and splinter resistant, unlike timber trims
• No staining, oiling or sealing required

Performance Highlights

• Corrosion-resistant for long outdoor service life
• Weather and UV stable, so parts keep their fit and finish
• Consistent dimensions for reliable, repeatable installation
• Compatible with standard WPC decking profiles

Material & Durability

WPC composite with the same wood-fiber and recycled HDPE formulation as the deck boards. Parts are produced for outdoor decking use, where damp ground, rain and sun are the norm, so they are specified to resist corrosion, brittleness and loss of holding power over time.

Installation

Measured and cut to length on site, then fixed over the board ends with stainless-steel screws or construction adhesive.

Quality Assurance & Testing

Each production batch is checked for dimensional tolerance, strength and finish before shipment. Parts are produced to CE and RoHS requirements, and third-party inspection is welcome before shipment.
