LGS Building

MAJESTIC BUILDERS is giving wide variety in Light gauge steel construction. LGSC is very similar framing members with steel sections. The steel sections used here are called cold formed sections, meaning that the sections are formed, or given shape at room temperature. Cold formed steel is shaped by guiding thin sheets of steel through a series of rollers, each roller changing the shape very slightly, with the net result of converting a flat sheet of steel into a C shaped section.

The steel used here is coated with zinc (called galvanized) or a mixture of zinc and aluminum (called zincalume or galvalume by some) to protect it from corrosion. The thickness of this coating can be varied to suit a range of environments. The thicknesses of steel used here range from about 1 to 3mm for structural sections, and 1 to 2mm for non-structural sections.

A frame of steel members is first constructed, and then clad with dry sheeting on both sides to form a load bearing wall. Connections between members are made with self tapping/self drilling screws.

Light gauge steel structures have many of the advantages:

• They are light, and allow quick building without heavy tools or equipment.
• Every component can easily be carried by hand
• It is able to shape itself to any form, and can be clad and insulated with a wide range of materials.
• It is easy to change or modify this construction at any point in its lifespan.
• Light gauge steel structures are non-combustible, which is a code requirement for some types of structures.
• Light gauge steel structures do not rot, shrink, warp, or decompose like wood structures, and can be used in areas where there is a probability of termite attack.  

Steel is widely used in the construction of multi-storey buildings. However, steel construction is seldom used and is traditionally considered uneconomical for landed properties. In many parts of the world, timber or structural brickwork is preferred whereas in Singapore, reinforced concrete construction is usually preferred for landed properties.

Over the years, various improved systems have been developed for use in landed properties. An economical light gauge steel frame system is increasingly being used in America, Europe, Australia and New Zealand. This light gauge steel frame is developed through a cold-formed process without the use of heat. This process enables steel manufacturers to produce light-weight but high tensile steel sheets. The sheet surface is coated with a zinc alloy that completely covers the steel surface and seals it from the corrosive action of its environment. This results in buildings that are more solid, rigid, stronger, durable and easier to build.

As such, the light gauge steel frame system is an attractive alternative for use in landed properties. This is particularly in view of concerns on the depletion of timber resources and low productivities associated with reinforced concrete construction.

Buildability: The use of pre-fabricated and preassembled steel components reduces site works, reduces material waste and improves quality.

Speed: This system requires a shorter construction period compared to that for a conventional system.

Strong but Lightweight: Steel has one of the highest strength-to-weight ratios of any construction material. This results in savings in the foundation required and the lightness also makes for easier on-site handling.

Safety: Steel’s inherent strength and noncombustible qualities enable light steel frame houses to resist such devastating events as fires, earthquakes, and hurricanes. Homes can be designed to meet the highest seismic and wind load specifications in any part of the country.

Quality: A better quality finished house that is durable and low in maintenance.

Easy to Remodel: Remodeling can be easily accomplished. Non-load bearing walls can be readily relocated, removed or altered.

Design Flexibility: Because of its strength, steel can span longer lengths, offering larger open spaces and increased design flexibility without requiring intermediate columns or load bearing walls.

Recyclable: All steel products are recyclable.
