Cast Iron
Iron formed by pouring molten metal into a mold. It feels heavy and solid, with rounded cast details, a slightly rough skin, and a brittle character compared with rolled steel.

Choosing points
- Best for legs, grilles, stoves, railings, and exterior metalwork where a heavy classical industrial feel is needed.
- Cast surfaces often have subtle pitting and rounded details from the mold.
- Painted cast iron chips at edges first, revealing orange rust beneath.
- It communicates weight and permanence more than precision.
How it ages
- Strong in compression and long-lived when painted or seasoned, but cracks are harder to repair than mild steel bends.
What to avoid
- Do not leave cast iron unprotected in wet or exterior locations unless rust, coating maintenance, and drainage are part of the design.
