| aim at ideal living |
Living is a basics mankind and society.We think about living with a sense of relief and comfortable. What is an ideal living in the 21st century through steel? What kind of living will we be richer? What is an ideal living you desire? The result is "a steel house". a steel house is realized high reliance and comfortable by high technique. |
|
| to be kind to mankind |
It is a big chance of thinking about living. Hereafter lining needs strong and last long. A steel house has earthquake-proof and durability. Its air-tightness is made comfortable living. A strong living means to be kind to mankind. A family feels comfortable by reliable steel house. |
|
| to be kind to the earth |
Mankind lives with green. Favor forests make green. Materials of frame can be recycled which make using woods decrease and last long. So good environment is kept as a steel house is lived with the earth or a nature. |
|
| living by development basic strong of a steel house |
Japanese houses have long history is used woods for poles and beams. Since nineteen sixties poles and beams were used by a way of steel frame pivot. Since nineteen seventies a way of wooden frame of wall structure was introduced that means without poles or beams. A steel house’s material is from woods to steel or a way is from pivot to frame. A steel house has steel and a way of frame wall strong. So it is in the van of new era. Gentle warm woods and strong steel make new pleasure. Surface of bright and grace. Appearance of refined insists. A steel house can be designed many kinds of appearances. |

| intensity 1.5 times to wooden 2 × 4 / magnification of wall 6.5 times real power |
To compare wall panel of a steel house with wooden 2×4. A steel house has intensity 1.5 times. Magnification of wall is basic of strong, 2×4is 4.5 times and a steel house is 6.5 times. It does not change thickness of wall, 2×4 wall panel can be correspond to a three-storied building. Replying analysis is carried out as same way for skyscraper. A result of analysis is put in not damaging area, in occasion strictly short cycle eminent earthquake (TAFT EW) 1/300 max. Transformation angle by Hanshin Earthquake Disaster. It proves safe for great earthquake, because design basic lower limit is 1/60 means a receiving of power. |

* Wall magnification means --- design intensity to horizontal power against a wall of enduring power.

| standard adoption of outside covered with adiabatic way / taking effect steady prevention dew |
A steel house is enveloped in adiabatic materials. It is standard outside adiabatic way. Outside adiabatic way ensures prevention of dew. Because its prevention makes steel be durable. We confirm that inside and surface do not have dew by verification of tests, confirmation of monitor houses, basic of computer simulation's analysis. |

|
| freely control adiabatic ability / pliable correspond to energy ?saving next generation |
Standard energy-save to next generation by Housing Loan Corporation wants better air-tightness, adiabatic of house than existing new energy-save. Outside adiabatic materials of KC type steel house can be change adiabatic materials thickness. But wooden 2×4 house has limited adiabatic materials of thickness, because its standard is fitting adiabatic materials. KC type steel house freely control adiabatic ability, so next generation energy-save can be correspond. We investigate house more comfortable and high quality.

|
| a steel house has little bend / as long as strong, not passing change |
Steel does not have passing change, but wood has passing change (dried shrinking, twist, warp, crack). Steel shuts well, not creaked floor. Creep phenomenon of bending is the worst trouble in wooden house. After 5 or 10 years guarantee term is over, no one can do anything. But a steel house is less bending (2/3) than wooden 2×4. It does not happen creep phenomenon, so after many years will pass it is same as a new house. |

| Note) creep phenomenon means --- transformation can not turn beginning, if it removes over weight. Because materials have weight, then it has transformation with time and time. |
| adopt strong steel by frame materials / strong steel houses |
a steel house rearranges about 1mm steel by wooden 2×4 way of frame materials. Steel is not only changing but also strong. Woods resources of protection by global scale. A steel house has a mission for strong maintenance. |
|
| not to be anxious about damage of white ants |
White ants almost eat up without surface of wood (only a bark), then in confusion exterminating is too late. A steel house has main materials steel, it makes you feel easy. White ants can not eat. A strong house is a matter of course. We recommend a steel house, because you can feel easy to live longer. |

| to use galvanization sheet copper which is the best ability by structure steel |
Structure of steel house uses steel is galvanization sheet copper. It is cultivated Japanese iron plate maker rust prevention. This sheet copper is estimated "rules of technique about durability in authorization of industrial housing ability" the best ability (prevention of rot) by Japan Housing Center. Galvanization sheet copper of high rust prevention uses outside adiabatic wall protects environment of outside. Surrounding zinc protects steel by a section of steel or cut of under construction. |

| to tie between relief and reliance/ drill screw is excellent for intensity & construction |
Drill screw is one of the most important materials of steel house. To select intensity and construction drill, then it manages galvanization same as steel frame. To compare nail of wooden house, this drill screw has durability for cutting and pulling out. So we can make strong houses. |
|
| supply for a large space / the greatest freely design of layout |
Layout can be free designed, because construction is strongest wall panel holds whole house from surroundings. It is possible to design not depending on a partition wall, we correspond to change layout in the future. A steel house can be made a space of 72m2 without a partition wall, because rational earthquake- proof design is based. |
|
| steel has durable structure for over 100 years |
We test, examine into durability at six monitor houses in Japan. Include from an area of seashore the worst corrosion environment to an area of mountain zone. A steel house which mankind actual live is examined corrosion galvanization sheet copper inside of wall or below floor. We have examined for 2 years, data analysis confirms steel has ever 100 years durability.

|
| safe & advanced , a steel house is kind to family |
A steel house can be freely design layout, because it realizes wide span. Barrier free design is break off steps differences, meter module method makes comfortable of space. From children to the old, and changing life style can be affected.
