Roll Forming machinery Used In Light Steel House Frame

Light Steel house’s advantage


1)Light steel structure’s technical and product is very mature, can be produced batch and batch.


2)Long usage life. Normally, it can be used about 275 year (this date from North America).


3)Light steel contruction house is more better for anti-earthquake, the house won’t fall down until the earthquake lower than 9th class.


4)Can bear strong wind well: our light steel construction can bear 12 class strong wind (1.5KN/㎡)


5)Light steel house is good for enviroment, it can be moved and the material can be reclycled.


6) Light steel house structure itself weight is ligt, only about 1/4 compare to concrecte structure, so the foundation is more easy to build.


7) Compare to wood house, light steel structure house is good for anti white ant.


8)The whouse house is stable and low cost.


9)Light steel structure inside space cover is more bigger than concrete building


10) Light steel building’s fitting part is easy for batch producing in factory


11)Light steel house can be finished in more short days to keep around enviroment in low noise


12) Light steel house is good for keep enviorment clean and less waste


13) The concrete building need about 40years drying completely, so the house will be wet and not good for human health. Also the light steel wall only need a little place, so it can save land space for building wall.


14) All the material for light steel house are machined in factory batch by batch, the accuracy is more better to ensure the house quality,other traditional construction type have no idea to reach like this.
