Through rolling and pressing thin measurement of sheet steel into goods, cold-formed metal framing can be produced as a general concern of products. These goods can also be created by functioning of sheet steel applying stamping; rolling or pressing in order to reform those sheets steel into functional products. In all sections of manufacturing of enduring goods such as automobiles and apparatus, these cold metals can be used customarily.
Nevertheless, here is no doubt that these cold form metals mostly describe the constructions materials. We can even see that popularity of usage of cold-formed metals as in construction materials from the very beginning of codified standards in 1946. It has become more and more approved in building construction.
Moreover, not only structural but also non-structural elements are being produced from thin gauges of cold-formed sheet steels, at present in construction industry. For instance, columns, beams, joists, studs, floor decking, built-up sections and many more mechanical elements are included in these building construction materials.
There is a difference between cold-formed steel and other steel construction materials which are normally considered as hot-rolled steel similar to structural steel. On the contrary, cold-formed metals are manufactured under room temperature by rolling and pressing.
The most interesting part is that the force of materials is used in order to design and construction which is in general controlled by buckling. There is some similarity between construction practices and timber framing because of their using screws to manufacture stud frames.
Likewise, cold formed metal framing, regarded as light gauge metal framing (LGMF) by which, wood stick framing has been overtaken in both commercial and institutional construction. Some residential applications are also being operated through it. Furthermore, there are a lot of benefits of cold metal framing for example, light weight, no warping, easy cutting, and fast installation.
There are many shapes and sizes of cold-formed metal framing. As specimen,
Metal Stud Sizes is a wide stud of having a common size of 3 5/8″. It gives 4 7/8″ 0f thick wall combining with a layer of gypsum wall board.
Shaftwall /C-H Stud Sizes is accessible for only one side wall. As there is no floor on one side of the wall in mechanical shafts, Shaftwall is suitable for it. Here, the installation of gypsum wall board is constructed usually from the floor side of the wall.
Metal Furring Sizes are generally utilizing gypsum wall board to concrete as well as CMU block wall.
Thereafter, if we look for the standards that control the production and physical requirements of cold-formed metal framing products, we will find some structural and non-structural standards.
AISI NASPEC 2001 w/ 2004 supplement, ASTM A1003 Material specification, ASTM C653 Coating specification and many more are the specimen of non-structural standards.
On the other hand, ASTM C955 Load-bearing steel framing, AISI NASPEC 2001 w/ 2004 supplement, ASTM A1003 Material specification for steel sheet requirements, ASTM C1007 Installation are examples of structural framing standards.
In addition, Cold-formed metal framing gives a building landscape that creates the variation of construction, structural and non-structural elements of builing.
