Terra Deck – Steel Grey – Bullnose

The Terra Deck Steel Grey Bullnose brings a rounded, finished edge to deck stairs in the same cool grey tone as the decking board. Built at 137mm x 23mm x 5400mm using the Gen 5 co-extrusion process, it’s made to keep that colour consistent from the deck surface right down each step.

• Rounded bullnose edge, purpose-built for stair treads and step edges.
• Matches the Steel Grey tone used across the decking and fascia board.
• Circular hollow core, in line with the base decking board’s construction.
• Gen 5 co-extruded surface, helping the grey tone hold up under regular UV exposure.
• Textured wood-grain surface, giving some grip underfoot.
• No oiling, painting or sealing required.

(Dimensions: 137mm x 23mm x 5400mm)

Applications & Suitable Uses

• Deck stair treads – Their main purpose is to give each step a rounded, finished edge.
• Contemporary homes with charcoal or black exterior tones – Suits a grey-and-black outdoor palette.
• Raised deck or balcony edges – Works as a rounded alternative to flat fascia.
• Steel Grey decking and fascia projects – Keep the whole structure, including the stairs, visually consistent.
• Concrete or minimalist landscaping – Pairs naturally with hard, modern surrounding surfaces.

Why Choose Terra Deck – Steel Grey – Bullnose?

Stair edges see more daily impact than almost anywhere else on a deck, and a plain squared board doesn’t hold up as well there over time. The rounded bullnose profile spreads more evenly across each step while keeping the same Steel Grey tone as the rest of the deck. It is a practical way to ensure the staircase looks like it belongs to the same build, rather than something added on separately.
