Prefabricated building H steel framework product is a new construction industry in recent year. Nowadays many warehouses adapt steel structure as the main frame. It's a trend that steel structure will replace concrete construction.
H steel structure house has short construction period, all processing of beam columns are accomplished through production line in the factory. The structure is light, which can be processing as well as making foundation. After foundation was finished, structure can be installed. Like this, construction period can be shortening. Bolt fastening makes the installation more convenient. H steel framework products have good solderability, during the jointing process and after that, the jointing place won't be cracking. Due to the development of jointing technical, jointing structure simplified the connection of steel structure.
H steel framework houses have good function of disassemble and assemble, after disassemble, the houses still can be used, which greatly decreased cost. Compared with concrete trestle houses, construction period can be decreased a half, the cost would be decreased by 20%--30%.
Because of the steel is intensive, high elasticity modulus, the steel structure is small and light. In the same stress condition, its deadweight is small and the span can be bigger. The member bar is small and convenient to transfer and installation. Steel structure has good function of plasticity and toughness which suited to bear attack and dynamic loading, earthquake-resistance.
This kind of structure has good environment suitability, which can be extensively used in factory and warehouse.
