Cast iron is made from pig iron, which is one of the byproducts of the iron ore processing industry. It may contain scrap iron and scrap steel with undesirable elements such as phosphorus and sulfur burned away. Additional carbon and silicon or other elements may be added as alloys for particular properties. Cast iron is easy to mold into shapes and so is used for a variety of construction and industrial materials. It can be cast into gutter materials in a range of shapes and textures. Cast iron gutters can last up to 100 years, making it a good choice for those who want to avoid the recurring expense of replacing the gutter systems on their home. Cast iron gutters are recyclable, making them a sustainable building product for home construction use.
Cast iron guttering gives a home a solid, traditional look that recalls the elegance of past ages. Cast iron gutters can be installed easily with suitable fasteners that are available from the manufacturer. These gutters are durable and will not crack or shear like vinyl materials. They are wind-resistant and can withstand impacts, according to the Classical Rainwater website. Cast iron gutters will increase the value of your home because of their durability and visual appeal.
Cast iron guttering is more expense than other materials, such as metal or vinyl. It is also heavier than other gutter materials, which may be a problem for do-it-yourselfers. Cast iron needs more frequent repainting to seal the surface and prevent corrosion from moisture.
Cast iron gutters are easy to maintain. Like other gutters, you must periodically remove dirt, leaves and other materials in the gutters to allow rainwater to flow freely. Adhesive materials at the joints of the guttering may dry out and require replacement for a tight fit, according to writer Jeff Howell of The Telegraph newspaper website. Cast iron gutters also require periodic brushing with a wire brush to remove corrosion. You can then prime and paint the gutter system to look like new.
