Light weight: Steel has high strength and flexibility. Compared with traditional reinforced concrete buildings, it has high strength, light weight, good rigidity of the entire rigid frame and strong forming ability. The building's weight is only one-fifth of that of a brick-concrete structure, and it can withstand a typhoon of 70 meters per second, so that life and property can be effectively protected.
Seismic resistance: Steel-structured houses have good life safety performance in earthquakes. Most steel-structured roofs are sloped roofs, so the roof structure basically adopts a triangular roof truss system made of cold-formed steel components. After the light steel components are sealed with structural plates and color steel plates, a very strong plate-rib structure system is formed." This structural system has stronger earthquake resistance and resistance to horizontal mounting, and is suitable for areas with an earthquake intensity of more than 8 degrees.
Durability: The steel-structured housing structure is entirely composed of cold-formed thin-walled steel component systems, and the steel bars are made of super-corrosion-resistant high-strength hot-rolled galvanized plates, which effectively prevent the influence of rust on the steel plates during construction and use, and increase the service life of light steel components. The service life of the main structure can reach more than 50 years. Economical, the construction of steel structure is simple, open and day-to-day, so its overall cost is one-third of the general concrete structure, and its operating profit is one-third of the general structure. Comparison: concrete structure: 800-1500 yuan/square meter; mobile house: 220 yuan/square meter: steel structure: 260-500 yuan/square meter, which greatly controls the cost. The construction of steel structure building is very simple, and its self-weight is very light, so its overall cost is one-third of the general reinforced concrete structure.
Flexibility: With flexibility and richness. The large bay design, the indoor space can be divided in multiple ways to meet the different needs of users, which brings huge design space to the designer.
Insulation: The insulation and sound insulation materials adopted by steel structure are mainly sandwich panels, and the wall products mainly include color steel sandwich panels, rock wool sandwich panels, etc., which have excellent insulation and sound insulation effects. The insulation board used for partition walls achieves better insulation effect. The thermal resistance of 100MM thick R15 fresh-keeping cotton is equivalent to that of 1M thick M24 brick wall.
Thermal insulation: Thermal insulation effect is a major indicator for evaluating housing. The windows installed in the light steel system all use hollow glass, which has good thermal insulation effect and can reach more than 40 decibels; the wall composed of light steel frame and color steel plate can have a thermal insulation effect of up to 60 decibels. It is two-thirds of concrete and twice that of wooden structure.
