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%, 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. What is the Color of foam sandwich? Color Color foam sandwich by two volumes, also known as (steel tile), intermediate ordinary foam, polystyrene, extruded polystyrene, polyurethane, polyester and wool three, etc., have been used in the Pan Large steel industry steel plant sheds, warehouses and workshops, gymnasium Guangzhou Steel Company, Color flow room, Color integrated housing, clean shop and the need insulation fire place. Color Volume is a sophisticated technology and steel complex mix of bright luster peritoneal synthetic one, no surface decoration, color steel coil coating retention period of 10-15 years. Color foam sandwich beautiful shape, luster bright steel, the overall effect is good insulation and strong steel processing Dongguan, fire, water effects, color steel sandwich panels with foam without having to re-decoration, to facilitate quick installation and construction period short, is a versatile, very high potential of green building materials.
