Lightweight steel structure and reinforced concrete frame structure home self-build home that cost is lower

Lightweight steel structure is less than reinforced concrete frame structure. First of all, light steel structure foundation is relatively simple, if the foundation of the concrete frame must consider the structure of its own weight load, which has produced a large cost difference, second, although steel is more expensive than concrete, but eliminates the reinforcement, formwork, concrete and a lot of labor and time (concrete to wait until the age of the full before the removal of the mold), third, the waste of steel (steel) can be controlled, as long as the length of the modulus of the purchase of materials, the excess part of the set of cut applicable to almost no waste! Third, the waste of steel (light steel) is controllable, as long as the material is purchased in accordance with the length of the module, the excess is applied to the set of cuts, almost no waste.
