The Different Types Of Iron Used For Ornamental Designs
Iron fencing is one of the most popular options for a stately, elegant look. Many times, iron fences surround gated communities or wealthy estates, so they suggest an element of prestige. One of the most striking elements of the fences are ornamental designs that complement them with a touch of flair. These ornamentations are made with different types of iron, all with their own unique characteristics.
Wrought iron is one of the most common, and one of the most widely known types of iron that is used in fences. It’s an iron alloy with a very low carbon content, much lower than that of cast iron. It’s tough and malleable, and it has a grain resembling wood. Wrought iron was first used in ornamentation in the 18th century. Before then, it was usually used for industrial purposes, such as in straps, nails, and other hardware. Around 1850 is started to be used for decorative purposes, such as in balconies and railings, as well as fences and gates.
Cast iron is a ferrous alloy that’s been heated until it’s liquified and then poured in a cast to make a form, hence the name. It was big in the 19th century during the Industrial Revolution. It was primarily used in buildings, which were being constructed at a quick rate. The drawback of cast iron is that is brittle, but it is strong when compressed. It was also used in stairs, balconies, railings and fences in the 19th century.
Sheet iron, or iron that comes in thin, flat pieces is sometimes used for decoration. It is more often used on ceilings to make intricate patterns. Since it has a tendency to rust and corrode, it is not often used outdoors.
Steel is a strong iron and carbon alloy that has high tensile strength and low cost. It has hardening agents that prevent the iron atoms within it from moving or dislocating. It was introduced at the end of the 19th century when it allowed for the construction of tall buildings. Steel’s disadvantage is that when it gets hot, it loses strength, so steel structures have to be fireproofed in some way. Stainless steel is a decorative steel that’s often used in buildings. It’s resistant to corrosion and contains chromium and nickel. However, it’s expensive, so it’s primarily used for decorative purposes, not structural. Another type of decorative steel it copper-bearing steel, which contains copper to make it resistant to atmospheric corrosion.
You see that iron isn’t as simple are you might have thought.
