In the construction site, we often see all kinds of colorful activity rooms, which is very convenient for construction workers. However, many people are not very clear whether the roof material is color steel plate or color steel sandwich plate. Today, Jinan color steel plate manufacturer will tell you the difference between the two.
The coating of color steel plate is made of cold rolled steel plate and galvanized steel plate, which is coated (roll coating) or composite organic film (PVC film, etc.) after surface chemical treatment, and then cured by baking. Some people also call this kind of product "pre roll coated color steel plate" and "plastic color steel plate".
Color steel sandwich panel is a common product in the current building materials, which can not only have good flame retardant and sound insulation, but also environmental protection. The color steel sandwich panel is made by pressing the upper and lower metal panels and the middle polymer heat insulation inner core. Moreover, the closed bubble molecular structure used in the filling system can prevent the condensation of water vapor. The forming of outer steel plate fully considers the requirements of structure and strength, and takes into account the beauty. The inner surface layer is formed as a flat plate to meet various needs. There are two kinds of metal panel and non-metal panel. The metal panel is easy to process and can be made into various shapes, but in some cases, the non-metal panel has a better effect than the metal panel, such as corrosion resistance, impact resistance and so on.
The color steel sandwich panel not only has the properties of high mechanical strength and easy forming of steel materials, but also has the good decorative and corrosion resistance of coating materials. Color steel sandwich panel is a new material in the world. With the progress of science and technology, the enhancement of environmental awareness, and the improvement of people's living standards, the color steel sandwich panel activity room shows more and more strong vitality and broad market prospects, and is favored by architecture, household appliances, electromechanical, transportation, interior decoration, office appliances and other industries.
Good thermal insulation. The common thermal insulation materials of the color steel plate composite board are: rock wool, glass fiber cotton, polystyrene (EPS), polyurethane, etc., with low thermal conductivity, so that the activity room, integrated house, steel structure workshop, etc. have good thermal insulation effect. High strength color steel plate uses high strength steel plate as base material (tensile strength 5600kg / cm), plus advanced design and rolling forming. Therefore, the color steel plate mobile house has good structural characteristics
The core of color steel sandwich panels is mainly phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, three polyester and rock wool, etc. phenolic foam has excellent fire resistance and heat preservation performance. It is irreplaceable for other materials. For example, phenolic foam insulation is more than 2 times of polyphenylene, and its fire resistance is higher than that of polyurethane. thick smoke.
Jinan color steel plate and color steel sandwich plate are different in material, production process, use and so on. Of course, the price is also slightly different. The price of color steel sandwich plate is higher than that of color steel plate. The above is today's color steel plate manufacturers to share all the content, I hope to help you.
