Terra Deck – Steel Grey Fascia Board

Steel Grey is the decking colour that modern Melbourne builders keep reaching for — and the fascia board that finishes it deserves the same deliberate approach.

The Terra Deck Steel Grey Fascia Board measures 140x10x5400mm in solid Gen 5 co-extrusion WPC. It’s engineered to cap the exposed perimeter of your deck frame with the exact grey tone of the Steel Grey decking surface — not a close match, but a precise one, because both the decking boards and fascia go through the same Gen 5 polymer cap process in the same colourway.

In terms of aesthetics, Steel Grey fascia is the natural partner for any home with a contemporary-minimalist design direction. It reads clean against concrete, white and off-white render, charcoal cladding, and black-framed glazing. The brushed-timber texture on the surface adds enough visual interest to prevent the grey from feeling flat or industrial while still sitting back from the overall design.

The solid 10mm profile handles fascia duty well — it sits flush and firm, holds fixings cleanly, and resists the flexing that a hollow profile at this thickness would exhibit over time. Face-fix with pre-drilled stainless screws or composite decking screws. Colour-matched fixings eliminate any visible hardware contrast.

Because UV bleaching is the primary risk for grey composite boards in Melbourne’s climate, the Gen 5 cap is particularly important here. It’s UV-stabilised across all four sides, which means the fascia holds its steel grey tone through multiple Australian summers rather than lightening to an indeterminate pale grey.
