LGSF

Product Description:   Light Guage steel structure system LGSF, modern technology in most developed countries like USA, Canada, Australia and Japan are widely in use in some states, as the bulk of the construction by this method takes place. This technology has been used in Pakistan for several years as an affordable solution for rapid, light & sustainable construction.

With H.H Robertson’s Light Guage steel frame products, you can turn architectural inspiration into commercial reality much faster and more cost effectively than ever before for Small to Mid-Size Buildings.

The primary shapes used in construction are the C-shape stud and the U-shaped track, and a variety of other shapes. Framing members are generally produced in a thickness of 12 to 25 gauges.

Galvanized steel is the base material for light-gauge steel. Steel is then roll-formed into the final profiles used for framing. The sheets are zinc coated (galvanized) to prevent oxidation and corrosion. Steel framing provides excellent design flexibility due to the inherent strength of steel, which allows it to resist wind and earthquake loads.
Steel framing is inherently less energy efficient, Construction with steel framing contributes to thermal bridges between the outside environment and interior conditioned space.

Structural Frame The wall frames, roof trusses and floor joists (if applicable) are pre-engineered and framed using cold formed steel sections, in a very short span of time.
  • A factory-built quality and precision
  • Compliant with relevant building codes
  • Wind and Earthquake resistant
  • Wide span

Steel Properties Thickness: 0.6mm to 1.20mm (24g – 18g)
Yield Strength: 250-345 MPa

As a SMART AND FLEXIBLE building system, LGSF is fast getting popular as the preferred method of construction for an array of applications.
SITE AND PROJECT OFFICE LGSF system, due to its speed of construction, is an ideal solution for site office / building and the complete building is built before the commencement of the project.

ROOF TOP RESIDENTIAL / INDUSTRIAL The system is most suitable for roof top construction; due to its light weight it does not add any substantial load on the existing structure and is treated as a temporary structure

SCHOOL AND HEALTH CARE CENTRES In remote locations and hilly areas, it becomes difficult to carry out construction through conventional ways. A lightweight, fast and easy to build construction system , like LGSF, is the obvious choice where only the erection of the building is done at the site..

RESIDENTIAL BUNGLAW / GUEST HOUSE / FARM HOUSE Due to the systems ability to accept an array of interior and exterior finishing and a fast construction, LGSF is a preferred solution for building farmhouses, outhouses, villas and residential buildings, specially in the hilly areas.

External wall infill forms a secondary, lightweight structure, fixed onto the primary super-structure.
Typically positioned at the slab edge, Hadley Steel Framing provides support for insulation and external finishes creating a weathered envelope at an early stage helping to reduce the overall build timeline. Full height stud sections are located and screw fixed to the flanges to floor track section, itself fixed to the floor slab with fixings at intervals determined by structural calculations. The deep track slotted head section is similarly fixed to the underside of the upper floor slab in order to accommodate any deflection within the main frame.
  • Fixes to the primary frame
  • Provides secondary support for insulation and external wall finishes
  • Provides a weathered envelope early on in the build
  • Reduces the overall build programme, saving material weight, construction time and labour requirements
  • Cill, lintel and jamb configurations are available to ensure the most economical design

Partition Walls/Separating Walls An economical friction-fit system to assemble frames for strong, compact, lightweight non load-bearing partitions. The metal stud partitioning is ideal for use in domestic and commercial situations, for heights up to 10m and a wide range of partition thicknesses.

  • Stud and track formed from pre-galvanized
LGSF CONINUOS WALLING Continuous walling is where the SFS is designed so that it ‘over sails’ the edge of the primary structure. This method is often used when a design team wants to maximize the amount of internal floor area or if they are using a cladding which cannot accommodate horizontal deflection joints at each floor level. Continuous walling is typically constructed from the outside of the building.

High Bay Walls High bay walls are similar to infill walls, except they are used internally to provide high separating walls for factory units or atriums. As they are often constructed within hot rolled steel portal frames, the amount of primary frame deflection that needs to be accommodated can be much greater than required for infill panels and bespoke details are typically provided to suit project requirements. High-bay walls can be constructed up to 20m high and because of their lightweight construction there is rarely any need to provide additional foundations underneath the wall. The high strength to weight ratio of the studs enables these high separating walls to be constructed without any need for any hot rolled steel wind posts which would be necessary in an equivalent wall of masonry construction. Walls can also be designed to meet project specific acoustic and fire rating requirements
