a.Insulation：continuous thermal insulation can prevent hot and cold bridge. Energy-saving effect is superb.

 b.Heat proof：air layer takes the sun’s heat absorbed by the walls.

 c.Earthquake：The strong steel structure is integrated as a whole, and not easy to collapse. It is capable to resist strong earthquakes.

 d.Noise proof：compound wall can reduce noise effectively because sound is attenuated when passing different materials.

 e.Fire proof：incombustible materials and plasterboards are used to form firewalls.

 f.Fast：fast design, fast production, rapid assembly, rapid installation, and quick decoration.

 g.Precision：fully computer controlled so error in length is between 0 - 1mm.

 h.Thin wall：increase the use of space.

 i.Shape：roof truss can be easily applied in various shapes of buildings, and roof space is also usable.

 j.Light：Weight of a house is 1/5th -1/6th of a steel concrete structure, so it reduces construction costs.

 k.Durable：The special anti-rust surface treatment on steel can guarantee quality in long-term.

 l.Environmental protection：steel is recyclable and renewable resource, in line with the philosophy of environmental protection.

 m.Pipeline：a variety of pipelines can be installed in walls, floor beams and roof trusses.

 n.Scaffolding：outer scaffolding is unnecessary when constructing, it makes installation easy and quick.

 o.Frame section：the complete structure, including the stairs uses same kind of steel. This simplifies preparation, and classification.

 p.Space：Lots of space can be realized, in order to re-create the conditions for housing layout.

 q.Production：frames can be produced in a factory and transported to the construction site or manufactured on the construction site.

 r.Accessories：components are mostly joint via flat surfaces. It does not require connectors, which simplifies preparation and installation.

 s.Variable cross-section beam：toilets, indoor balcony terrace can be below ground to prevent water to flow to the indoor.

 t.Screw：installation and construction using steel rivets and flat head screw simplifies preparation and classification.

 u.Combination of forces：the frames 3C and 4C combination ensures stability.

 v.Cross-up：cross-up enhances the overall strength, and it also provides conditions for decoration.

 w.Installation：Housing construction crane is not needed for installation.

 x.Construction：workers only need Pneumatic Riveter and electric screwdriver to install, no training is required.

 y.Usage of steel：15 ~ 25kg per square meter, decoration frames are not needed.

 z.Cost：only 200 to 300 yuan per square meter.
