Eco Deck Dual 360 bullnose composite deck boards are designed to provide a clean, professional finish for deck perimeters, stair treads, and picture-frame borders throughout Calgary and Alberta. Built to withstand demanding outdoor conditions, they offer the look of wood with the low-maintenance benefits of advanced composite materials. Available in 16 ft lengths, they help minimize seams for a more continuous, polished edge.

Whether you’re building a new deck in Calgary, updating stairs in Edmonton, or planning a project in Red Deer or surrounding communities, Dual 360 bullnose boards offer a durable finishing solution designed for long-term outdoor performance.

Dual 360 bullnose boards are designed specifically for exposed deck edges, stair fronts, and border detailing where a clean finish and added durability matter most.

Each board includes a solid composite profile for added strength in high-traffic areas, along with a rounded bullnose edge that creates a smooth transition at deck perimeters and stair treads. This makes them a practical option for homeowners and contractors seeking a professional finished appearance.

Each board is protected with Dual 360° Protective Shield Technology—a durable outer layer that helps resist moisture, fading, stains, mould, mildew, and everyday wear, supporting long-term colour stability.

Like all Dual 360 composite decking, bullnose boards require no staining or sealing, making them a low-maintenance finishing solution. 

Dual 360 bullnose boards are designed for applications that require a clean, exposed edge.

Common uses include:

• deck perimeters
• stair treads
• picture-frame borders
• step edges and transitions

The rounded front edge helps create a refined finished appearance, while the solid construction adds support and durability in areas where edge boards experience more wear.

For best results, install Dual 360 bullnose boards with matching deck boards and fascia boards, and compatible fasteners, as part of a complete decking system. 

From Calgary’s freeze-thaw cycles to temperature swings in Edmonton and Central Alberta, Dual 360 bullnose composite deck boards are made to perform reliably in demanding outdoor conditions. 

The protective outer layer is designed to:

• reduce moisture absorption
• improve resistance to fading and stains
• support long-term durability in exposed areas

This means Dual 360 bullnose boards are a dependable finishing solution for projects throughout Alberta and Western Canada.
