  Why do we use iron for furniture?

  Iron is the metal of choice for many of our pieces. This is due to the inherent strength of cast and wrought iron and its natural, neutral color scheme.

   

  Strength

  Cast iron is actually a carbon-iron alloy, while wrought iron is made entirely of iron. The carbon added during the cast iron process adds strength to the iron as it cools, while wrought iron retains the natural grain structure of iron, making it a stronger furniture material than any other alloy on the market, including bronze and bronze. Aluminum alloys.

   

  Design

  Iron has a naturally cool and neutral color. This makes it very versatile, as the color palette can match a variety of styles. The main styles that influence our iron furniture designs are mid-century modern, rustic modern and industrial modern, as elements of these styles complement the natural colors of the materials we use.

   

  How to identify cast iron

  The Victorian passion for gardens spawned a demand for cast iron outdoor furniture and lawn ornaments in the mid to late 1800s. At the time, cast iron was less expensive to manufacture and more popular than the more expensive wrought iron garden furniture that was popular in the early to mid-1800s. Lighter, stronger steel became more popular at the turn of the 20th century.

   

  Cast iron can be identified by the following.

  The manufacturer's mark or stamp: this will help you trace its history.

  Weight: If it's heavy, it's probably cast iron. However, don't stop there.

  Decoration: Cast iron was/is often decorated with classic motifs such as flowers, fruits and vines.

  Molded or formed: Furniture is made from carved molds and forged into curves and ornate patterns.

   

  Why we use cast iron in our furniture

  Durable - Cast iron is the material of choice for many automotive parts for a reason - it can withstand a lot of wear and tear.

  Proven technology - By using a system refined by dozens of generations of craftsmen, we not only pay homage to our predecessors, but also guarantee the highest quality of our work.

  Environmentally friendly and sustainable - After sand casting, the remaining scrap can be melted down for the next piece. This ensures that nothing is wasted.

   

  What is cast iron made of?

  Cast iron is one of the oldest ferrous metals used in construction and outdoor or exterior decoration. It is composed mainly of iron, carbon and silicon, but may also contain traces of sulfur, manganese and phosphorus. It has a fairly high carbon content of 2% to 5%. Unlike wrought iron, for example, cast iron is strong, heavy, unmalleable (it cannot be wrought or machined, bent, stretched, or hammered into shape), and more fusible. Although cast iron can break under extreme forces, it performs well under compression. Its composition and method of manufacture are critical in determining its properties.

   

  Cast iron is still manufactured using the same process as it has historically been. Iron ore is heated in a blast furnace along with coke and limestone. This process deoxygenates the ore and removes any impurities, resulting in iron. The iron is poured into a mold of the desired shape, which is allowed to cool and crystallize. If properly manufactured, cast iron forms a protective film or oxide skin on its surface, making it more resistant to corrosion than wrought iron or mild steel. Surface treatments, coatings or factory preservative treatments are used to prevent cast iron products from rusting (oxidizing) when exposed to moisture. These may include asphalt coatings, waxes, paints, galvanizing and electroplating.

   

  The most common traditional form is gray cast iron. Plain or gray cast iron is easily cast, but cannot be forged or machined, either hot or cold. In gray cast iron, the carbon content is distributed in thin sheets throughout the metal. In white cast iron, the carbon content is chemically bound as carbides of iron. White cast iron has excellent tensile strength and ductility. It is also known as malleable or ductile cast iron.

   

  Outdoor Use

  Because it is fairly inexpensive, durable, and can be easily cast into a variety of shapes, cast iron is still used for a wide range of structural and decorative purposes. These include.

  Garden furniture. At the White House, much of the white rococo outdoor furniture, such as benches or small dining tables, is made of cast iron, echoing the architectural style of the famous house.
