None

Based on the quantitative criteria of building on the basis of strength, durability, versatility, and economy, steel is a universal building material.The proven performance and quality of steel have also caused it to dominate commercial interior wall framing applications for many years now.  With the growing innovation the light gauge steel has continued to be used as an infill structure on multi-storey buildings built from hot rolled steel or concrete frames. Commercial and retail buildings continued to benefit from its diverse capabilities, using it as a cladding system which can be formed into many different shapes.Embracing innovation is the need of time. Lesser deadlines and economical hindrances have forced us to look out for ways that serve both time and quality, what better than a LGSF technology.

What is LGSF Technology?

Light Gauge Steel Framing (LGSF) is a construction technology that uses cold-formed steel sections to create a durable and efficient structural framework for buildings. In this approach, thin steel sheets are cold-formed into specific profiles, providing strength and flexibility. LGSF is known for its speed of construction, design adaptability, and cost-effectiveness. Prefabricated steel components are often used, allowing for quick on-site assembly. This construction method is suitable for a variety of building types, including residential, commercial, and industrial structures, and has gained popularity for its ability to meet modern construction challenges with a focus on efficiency, sustainability, and cost savings.

The LGSF technology primarily involves use of galvanised steel which is rust proof, mold resistant and waterproof and the steel offers resistance against any form of corrosion. Moreover, it is environment-friendly. As compared to concrete buildings, buildings with this new technology will offer various environmental benefits such as less energy is required to produce steel against concrete materials, cropping down of CO2 emissions against concrete structures and the ability to recycle the steel used to build the structure at the end of its life cycle.

How does LGSF work?

Light Gauge Steel Framing (LGSF) technology harnesses cold-formed steel sections to establish a robust structural framework for buildings.

Design and Engineering:

The process commences with meticulous design by architects and engineers. Computer-aided design (CAD) software is employed to ensure the structure meets specific requirements and adheres to necessary load-bearing capacities.

Manufacturing and Panelization:

In the manufacturing phase, cold-formed steel sections are produced from galvanized steel coils through processes like roll forming, shaping them into the desired profiles, and cutting them to specified lengths. These steel sections are assembled into panels or frames at the manufacturing facility, pre-engineered and pre-punched for efficient on-site assembly.

Transportation and On-Site Assembly:

Prefabricated panels are transported to the construction site, reducing the need for on-site fabrication and minimizing construction time. On-site, these prefabricated steel panels are efficiently erected and connected, forming the fundamental structural framework of the building.

Foundation and Structural Assembly:

A carefully prepared foundation, in line with the building design, provides a stable base for the steel structure. The prefabricated steel panels are then assembled to create the structural framework.

Component Addition and Finishing:

Following the structural assembly, additional building components such as insulation, sheathing, windows, doors, and interior finishes are added to complete the structure. Exterior and interior finishes are applied to achieve the desired appearance and functionality.

Utilities and Integration:

Plumbing, electrical, and other utility services are seamlessly integrated into the structure as needed, ensuring the building meets both functional and regulatory standards.
