Composite Deck Trims

Composite Deck Trims & L-Edging

Wood Plastic Composite (WPC) Deck Trim is the essential finishing component for any professional composite decking project. Serving both structural and aesthetic functions, composite deck trims create a polished, architectural finish around deck perimeters while shielding exposed board edges from moisture ingress, physical impact, and environmental wear.

Manufactured from the same high-performance blend of reclaimed bamboo fibers and recycled plastics as our NewStead composite decking boards, our L-shaped deck trim guarantees an exact color and texture match across your outdoor living space - delivering the same low-maintenance, weather-resistant performance.

Product Design & Functional Application

Our L-shaped corner trim is specifically engineered to neatly cap exposed board ends where two fascia boards intersect at a 90-degree corner, or where deck surface boards terminate against an adjacent house wall, structural post, or step riser.

• Conceals Cut Board Ends: Covers raw board cuts and minor joist spacing gaps for a crisp, high-end profile.
• Seamless Edge Protection: Guards high-traffic deck corners and stair treads against accidental impact damage and chipping.
• Architectural Integration: Provides a clean transit line between deck boards, rim joists, and vertical wall cladding.

Installation & Trade Best Practices

Follow these contractor guidelines to ensure proper thermal movement and long-term trim stability:

• Face-Fastening Installation: Deck trim is face-fastened to the rim joist or framing substructure using color-matched composite deck screws or specialized fascia screws (fasteners supplied separately).
• Pre-Drilling Requirements: Because WPC materials naturally expand and contract with temperature shifts, always pre-drill pilot holes through the trim before driving screws to prevent splitting or cracking.
• Expansion Gap Spacing: Allow expansion gaps of 1/8" to 1/4" (3 mm to 7 mm) between trim board ends and adjacent walls to accommodate natural thermal movement.
• Screw Placement & Over-Tightening: Space fasteners according to manufacturer guidelines and avoid over-tightening screws to allow the material to flex without warping or buckling.
