Steel Rebars
Steel rebar, also known as reinforcement steel, is a steel bar used for reinforcing concrete and masonry structures. It is commonly used for bridge, building and construction projects, forming the temporary and non-structural framework of a structure during construction. Rebar is also commonly used in landscaping, retaining walls, sports fields, parking lots and in other ground structures.
The earliest known use of steel rebar dates back to medieval Germany when it was introduced by Johann Friedrich Appel into the building trade. Appel used many different types of steel, ranging from 15mm to 250mm in diameter, and his use of steel rebar spread to neighboring countries, including England and France.
Today, steel rebar is produced by a variety of methods. One method, continuously cast and rolled, involves the use of molds to form long strands of rebar that are then rolled into their desired sizes. This method is believed to produce the highest quality and most consistent reinforcement steel.
Steel rebar is most commonly available in 6 to 8 mm diameters, although it can be produced in diameters of up to 60 mm. It is also available in a variety of grades and strengths for to meet different building requirements. Grade 40 is the most popular, and is suitable for most non-structural applications.
In addition to its strength and durability, steel rebar has several other benefits as well. Because it is durable and strong, steel rebar is an economical material that can last for decades with minimal upkeep. It is also more resistant to fire and corrosion than other materials, and can withstand temperatures up to 700 degrees Fahrenheit. Steel rebar is also noncombustible, which makes it a great material for buildings situated near bodies of water or airports.
Steel rebar is also known for its ease of use and installation. Unlike many other materials, steel rebar does not require any additional brackets, braces or fasteners. This makes it a great material for interior and exterior walls, because it can be easily cut, bent and shaped to fit the desired application.
Steel rebar also has an environmental advantage. As an extremely durable material, it can be recycled to be reused in future projects. This allows it to be used over and over, greatly reducing the use of valuable natural resources.
Steel rebar is an essential part of the construction trade. It is used in a variety of applications in engineering, architecture and landscaping. Thanks to its strength and durability, steel rebar has been used for centuries and will continue to have an important role in the construction industry for many years to come.
