Steel buildings are common all over the World. The usage of steel in construction is a not a new practice. However emerging technology changes the type of construction materials we use. This is also applicable to steel.
Earlier hot rolled sheets were in use, which were manufactured at elevated temperatures. This structural steel is rolled unto its shape while hot at a temperature of 1700 degree Fahrenheit. The hot rolled steel shows lesser degree of accuracy than the cold formed steel hence its use is increasing worldwide.
The cold processed steel comes with much more plus points than the hot rolled steel does. This steel sheets are processed at scalable temperature to form shapes of building sections as desired. This type of steel is easy to handle, light weight and is easy to use.
This type of steel is mostly used in prefabricated buildings. In such type of construction, steel sheets are used to make the desired section. These are than transported to the building site. Most important sections are steel roof, wall panel, wall studs and floor decks. In the manufacturing units cold roll forming or press breaking accords the desired shape to the sections.
For production of roof, floor and wall panels' cold roll forming is mostly used. This material is also employed for important structural components.
The cold process increases the strength of the section, hence it is preferred. The yield point and tensile strength depends upon the type of the steel used and also on the type of cold forming.
Cold formed steel prefabricated section finds use in multiple applications. The manufacture in factories and installations at the site is beneficial. This saves both the time and money. In building construction, the doors and windows are also made from this steel. In highway construction, the guard rail and barriers are manufactured using cold formed steel. Transportation does not pose much of a problem as the material is light weight.
The sections formed using the cold formed steel are often used for the entire building. The material is also used for making the roof, floor and wall systems. The material is also used for making framing members such as studs, joists and truss. The primary as well as secondary structures are also made of light gauge steel. The load bearing steel stud wall is a fine example of primary structure used in commercial and residential buildings.
Hence hospitals, hotels, education institutes, research institutions all prefer the prefab ฝากขายคอนโด construction technique. In India government offices prefer steel construction to traditional building methods.
Resistance to fire, rot, fungi, algae etc are plus points of this material. The ability to gel with many types of paints and coatings also helps. Cold formed steel is strong, durable and ductile material.
