Container-style Color Steel House Roof
The container-style color steel house roof possesses multiple characteristics such as waterproofing, fire resistance, and thermal insulation, and there are various types of roofs available.
Waterproof Characteristics: The temporary container houses from the Rongsheng brand feature waterproof color steel roofs that effectively prevent rainwater penetration, ensuring a dry indoor environment suitable for use in various climatic conditions and providing reliable waterproof protection for living or working spaces.
Fire-resistant Characteristics: These roofs have a fire rating of approximately B1, offering certain flame-retardant properties. Additionally, in the enclosure structures of color-steel houses on construction sites in Tuyou Banner, if rock wool is selected for the intermediate sandwich layer, it is classified as an A-grade non-combustible material with a melting point exceeding 1000 degrees Celsius, effectively preventing the spread of fire and significantly enhancing the fire safety of the houses. If polyurethane foam is chosen, although its fire-resistant performance is not as good as rock wool, its closed-cell rate can reach over 95%, which can also slow down the spread of fire to a certain extent.
Thermal Insulation Characteristics: The outer steel plate is made of hot-dip galvanized substrate with a polyester resin coating on the surface, which can reflect part of the solar radiation heat and reduce heat transmission. When polyurethane foam is selected for the intermediate sandwich layer, its thermal conductivity is as low as 0.022 watts per meter per Kelvin, reducing indoor heat loss in winter and providing good thermal insulation. Furthermore, some color-steel house roofs are equipped with an air gap layer, with an additional sunshade board installed above the roof panel, forming an air circulation zone 20 to 30 centimeters high. This utilizes the thermal pressure difference to drive air flow, reducing the amount of heat transmitted into the room by approximately 30% and further enhancing the thermal insulation effect.
Diverse Roof Types: There are various types of container houses with different roofs available on the market, such as the Jingweida double-slope roof K-style color steel plate movable house in Jinan, Shandong, the four-slope roof container packing house installed in Tianjin, and the Hongzong four-slope roof packing house in Lianyungang, Jiangsu. Different roof types have their own characteristics in terms of drainage, aesthetics, and space utilization, and can be selected according to actual needs and usage scenarios.
