What is Cast Iron?
Cast iron is an iron alloy with a high carbon content (2–4%) and is known for its robust appearance and detailed finish. Because the molten material is poured into a mould, even the smallest ornaments can be created. This makes it popular for decorative applications in interiors, such as cabinet knobs that add an extra touch of character to furniture.
A Short History
During the 18th and 19th centuries, cast iron became increasingly popular in both industry and architecture — from bridges and railings to household objects. Cabinet and drawer handles also found their place in many homes. The material combines strength with craftsmanship, which is why cast iron remains widely used today in rustic and industrial styles.
Indoor and Outdoor Use
Indoors, cast iron is extremely durable: products such as hinges or furniture fittings stay beautiful and functional for many years with little maintenance. For outdoor use, extra protection is important. Uncoated cast iron can rust when exposed to moisture or salty air, so it’s often finished with paint or wax — or deliberately left to develop a natural weathered patina.
Best Installation Practices
When installing, care is essential. Cast iron is strong but brittle: it can crack if screws are overtightened or inserted at an angle. Always use a flat, stable surface and tighten screws slowly and evenly, ideally by hand. For products such as door handles, use matching screws that suit the material to ensure a secure and lasting fit.
Cleaning and Care
Maintenance is simple. A soft cloth and lukewarm water are usually sufficient. Avoid harsh cleaners or abrasive sponges, as these can damage the protective layer. To keep cast iron hardware looking its best, you can rub it occasionally with oil or wax. Painted or coated versions, such as many door handles or hinges, only need gentle cleaning; if damaged, treat the affected area promptly to prevent rust.
