Health: dry-construction, reduce waste pollution of the environment, housing material can be 100% recycled steel, other supporting materials may be most of the recovery, in line with current environmental awareness; all materials for green building steel structure, meet the ecological environment requirements are beneficial to health. ? Comfort: use of energy efficient light steel wall system, with respiratory function, can regulate indoor air humidity; roof with ventilation function, to form between the internal air flow over the house, to ensure the internal roof ventilation and cooling requirements. Shortcut: All dry-construction, without environmental impact season. A building about 300 square meters in Dongguan steel carport, just five workers 30 days to be completed from the foundation to the renovation of the entire process. Environmental: The material can be 100% recycled steel engineering company, truly green pollution. Energy: all use energy efficient walls, insulation, heat insulation, sound insulation, and can be up to 50% energy saving standards. First, the steel structure residential building energy than conventional buildings to better meet the requirements of large bays separated by flexible, and by reducing the cross-sectional area of ??the column and the use of lightweight wallboard, improve area utilization, effective use of the indoor area increased by about 6 %. Second, the energy saving effect, using light energy saving wall standardized C steel, good steel, sandwich panels, insulation properties, seismic degrees. Saving 50% of Guangdong Steel Company, three, the steel structure for residential buildings can take advantage of the ductility of steel, plastic deformation ability, excellent seismic performance wind, greatly improving the safety and reliability of residence. Especially in the event of an earthquake, typhoon disaster case, to avoid the collapse of the steel structure of the building damage. Fourth, the total construction light weight, light weight steel structure housing system, which is about half the concrete structure, can greatly reduce the cost base. Fifth, the construction speed, shorten the construction period than traditional housing system, at least one third, a 1,000 square meters just 20 days before the completion of five workers.
