THE MATERIAL IS THE DESIGN.

A copper-zinc alloy with a warm golden tone that deepens over time. We use solid brass exclusively — never plated, never clad. Plating wears through in years. Solid brass develops a patina that only improves. Heavier than steel by volume, softer to machine, and significantly more expensive. Every brass element in a Blackforge commission is there because no other material would do.

Brushed (directional satin, most common), polished (high mirror, requires ongoing maintenance), antiqued (chemically darkened for aged appearance), lacquered (clear coat to slow patina — we advise against this), raw (left to patina naturally — our recommendation for most applications).

Handles, handrail caps, inlay details, rosette elements, junction features, furniture hardware. Brass is the detail metal — it appears at the points where your hand meets the steel.

Pure elemental copper — one of the oldest metals in human use. Begins as a warm rose-gold, darkens to chocolate brown within months, and develops verdigris (the distinctive blue-green patina) over years to decades depending on climate and exposure. Cape Town's salt air accelerates the patina cycle. Copper is antimicrobial, infinitely recyclable, and requires zero maintenance if left to weather naturally.

Raw (our recommendation — let time do the work), patinated (chemically accelerated to a specific stage, then sealed), sealed at rose stage (lacquered while still new — stops the clock), waxed (slows patina, warm satin feel). We always present a patina timeline to clients so they understand what the surface will look like at 6 months, 2 years, and 10 years.

Cladding, water features, statement surfaces, sculptural elements. Copper is reserved for surfaces where the patina lifecycle is the design intent — where the piece is meant to change and improve over its lifetime.

Weathering steel — an alloy designed to rust on purpose. The surface develops a stable oxide layer that protects the underlying metal from further corrosion. No paint required. No maintenance. The patina deepens from orange to deep brown over 1–3 years, then stabilises. We weather all corten on-site before client handover so the initial orange phase happens under our control, not on the client's new terrace.

Natural weathering (the standard — we pre-weather for 3–6 months), accelerated patina (chemical treatment for faster oxidation), sealed at stage (clear coat applied at a specific patina depth), raw mill finish (silver-grey, not yet oxidised — rarely specified).

Firepits, exterior screens, garden sculpture, boundary walls, planters, water features. Corten is an exterior metal — it needs moisture and air to develop its protective layer. We don't recommend it for interior applications.
