The manufacturing methods have been greatly improved, and many shapes of sheeting profiles are now readily available. Steel sheeting is very simple to bend into various shapes, such as curved roof structures and cylindrical items such as culverts. The products are available in a wide range of coating options. The coating is usually done by the manufacturer, so the products are ready to use when they arrive.
Both structural and functional requirements can be met with cold-formed steel sheeting. The structural application is discussed in further depth in this work. Roof, wall, and floor structures commonly use profiled steel sheeting. The profiled steel sheeting truly meets both the structural and functional criteria in these constructions. Steel sheeting is frequently utilised in floor structures as part of a composite structure with concrete. The roof and wall constructions in northern countries are almost always built with thermal insulation. When designing structures, sound and fire insulation must also be taken into account.
The design of profiled steel sheeting is governed by a number of codes. For this purpose, almost every country has a national code, such as the DIN-code in Germany or the AISI-code in the United States. In Europe, structural design of profiled steel sheeting must adhere to Eurocode 3: part 1.3, while there are various national application documents (NAD) that include national criteria into the EC3. To compile the present design codes, a large number of tests were conducted and analysed, and there are several formulae in these codes that are based partly on theory and partly on experimental test findings. This paper discusses some of the most significant components of structural design for coldformed profiled steel sheeting. For thin-walled structures, a variety of various fastening systems have been devised. Bolts with nuts, blind rivets, self tapping screws, selfdrilling screws, and other types of fasteners are all suitable.
To be appropriate for cold-forming and, in most cases, galvanising, the materials used in cold-formed thin-wall members must meet certain criteria. The yield strength is generally between 220 and 350 N/mm2, but in some circumstances, high-strength sheet steels with yield strengths of above 500 N/mm2 are employed. The thickness of the material used in profiled sheeting is limited due to practical considerations such as transportation and handling.
Many fascinating research projects on the behaviour of profiled steel sheets have been carried out all around the world. This paper briefly summarises some of the most recent studies. The focus of research in various parts of the world is naturally on localised issues. In Australia, for example, the primary focus of cold-formed steel structure research is on the problems caused by high-wind and storm loads.
From 2021 to 2028, the global cold-formed steel framing business will rise at a compound annual growth rate of 4.6 percent. In the year 2021, the total market size of the global light gauge steel framing industry would be around $ 35.18 billion.Due to a significant increase in construction activities and its improved energy efficiency at a lower cost, market demand for Light Gauge steel framing (LGSF) is expanding day by day.
In this article, you’ll learn about light gauge steel frames, their benefits and applications in the construction business, and, most importantly, how understanding LGSF and its design can help you advance your career exponentially.

What Is Cold-Formed Steel?
Cold-formed steel members are constructed from structural quality steel sheets and utilised in the Light gauge steel framing system as a construction material.
The light gauge steel is cold-formed into the desired shape according to the design and can withstand severe weights. The term “cold-formed” refers to the shape of the LGSF sections as they are guided through a succession of rollers at room temperature.
Steel that has been cold formed A light gauge steel frame is also known as a cold framed steel frame (LGSF). Traditional Reinforced cement concrete buildings can be replaced with a light gauge steel frame.
The Light Gauge steel frame is a green building technology that allows for the rapid construction of residential and commercial structures. Building a light gauge steel frame structure follows the same principles as building a wooden frame structure.
The LGSF may be efficiently designed utilising STRAP software, which allows you to automatically optimise the design and deliver a cost-effective and economical structure.
So, let’s get right to the point: what prospects for growth do you have with STRAP?

Advantages of Cold-Formed Steel (LGSF)
The following are some of the benefits of employing cold-formed steel gauge in construction:
1. Effective in terms of time Time is crucial in construction projects, and the light gauge steel frame helps complete the project faster than traditional construction because essential components are manufactured off-site.The light gauge steel frame is quick and simple to put together, as well as transport and handle.
2. Budget-Friendly Cold-formed steel is lightweight and sturdy, therefore building frames require less material than concrete or wood, allowing for the construction of high-efficiency buildings at a low cost using a light gauge steel frame.
3. Termite resistance is excellent.Because the light gauge steel frame does not rust, warp, or shrink, it is ideal for usage in termite-prone areas.
4. It’s light. Cold framed steel gauge is lightweight, allowing structures to be constructed fast without the use of heavy tools and equipment.
5.It is inherently non-combustible. Light gauge steel constructions are non-combustible, which is an important feature in some structures.
6. Adaptable Light gauge steel frames are flexible, allowing them to be moulded into any shape or size required by the design.

Cold-formed steel (CFS) sections, also known as thin walled sections, are light-weight building materials that are ideal for building construction due to their adaptability in a variety of applications and ease of installation and manufacture. C sections and Z sections are commonly used in building construction, with section depths ranging from 0.1m to 0.35m and thicknesses ranging from 1.2 to 3.0 mm. CFS sections are rapidly evolving to the point that they are being used to construct light-weight flooring and framed structures. Light gauge steel building has emerged as a cost-effective alternative to standard structural systems. CFS framings provide a number of advantages, including being lower in weight and requiring less space.
In this research, G.Beulah Gnana Ananthi (2016) used ABAQUS software to do a non-linear (FEA) finite element analysis to forecast the structural nature of built-up CFS sections under axial loads. The behaviour of the CFS box double angle columns evaluated with axial compression with pinned-end condition is discussed in this work, which includes theoretical, experimental, and numerical research. The maximum load carrying capability of the built-up box angle column was calculated using an analytical model based on the Direct Strength Method. The parameter analysis’ numerical results were compared to the proposed approach as well as the present DSM equation.ROY Krishanu (2019), The revised version design guidelines and their accuracy have been proposed in this paper.
