Advantages

Safer: The premium physical and chemical performance of steel is better than other structural styles. Steel performs better in disasters such as earthquake, typhoon etc, so the use of steel structure is safer.

Durable: LGS housing is made from anti-corrosion galvanized steel and high strength steel. The structure is more durable and there is no need to worry about contribution to a fire.

Comfortable: The steel structure is moisture proof and insect proof. The living environment is more secure and comfortable.

Flexible: All pipes can be concealed in the walls or floor structure. The actual usage area is at least 5% more than traditional concrete buildings. The different living areas can be divided freely according to the design requirement and won't be restricted by the position of the load bearing walls.

Energy Saving: The Composite light weight and high strength floor and wall materials are insulated reducing noise and saving a lot of money in energy costs.

Environment Friendly: 100% light gauge housing frame is recyclable. There is no environmental pollution concern.

Design Flexibility: Light gauge steel construction can accommodate almost any style of residential buildings up to 3 floors. If it can be built with concrete, it can be built with steel.

Low Cost: Compared with concrete or other types of structures, a light gauge steel structure is light, and reduces the requirement on foundation loads, which can result in large scale savings in foundation costs.

Speed up: All the parts can be pre-fabricated in the factory and are quick to install. The sequence of design makes it possible to construct both internal and external walls simultaneously, which speeds up construction.

Quick Capital Turnover: The quick installation won't tie up developers' investment and can speed up retrieving capital and so reduce the investment risk and improve the investment benefit.

Environment Friendly:  Dry construction has little environmental pollution, as all parts are connected by screws. Construction is not affected by the season, and can continue in winter. There is little scrap left on site and no water is required in the construction process. 100% light gauge housing frame is recyclable.

Developing Trend: It is the developing trend in the global construction industry, whoever occupies the market first will have the best opportunities.
