We often see red or blue color steel movable rooms near the construction site, which is very convenient for construction projects. But is its roofing material color steel plate or color steel sandwich plate? How can steel plate manufacturers distinguish between these two kinds of steel plates when dividing colored steel plates? Which one is more insulating than the other? Today, the small edition of Jinan Caigang Steel Works will answer your questions.
1. Coating of coloured steel sheet is a product of cold rolled steel sheet and galvanized steel sheet, which is coated (rolled) or composite organic film (PVC film) after surface chemical treatment, and then cured by baking. Others call this product "pre-roll painted steel plate" and "plastic colored steel plate".
The color plate product is produced by the manufacturer in rolls on the continuous production line, so it is also called the color coated steel sheet roll. Coloured steel plate not only has the characteristics of high mechanical strength and easy forming of steel materials, but also has good decorative and corrosion resistance of coating materials. Coloured steel plate is a new material which is highly respected in the world today. With the progress of science and technology, the enhancement of environmental awareness and the improvement of people's living standards, the coloured steel plate movable room is showing more and more strong vitality and broad market prospects. It is subjected to construction, household appliances, electromechanical, transportation, interior decoration, office appliances and other industries. The favor of industry.
The color steel plate movable room has the advantages of light weight, high strength, heat preservation and insulation, beautiful and durable, etc. It is a fast building installation house which integrates building and decoration. Coloured steel sheet movable room construction clean, widely used in large-span factory buildings, warehouses, office buildings, villas, roof floors, air purification rooms, refrigerators, shops, kiosks and temporary rooms.
2. Color steel sandwich panel is a common product in current building materials, which can not only be good flame retardant and sound insulation, but also environmentally friendly and efficient. The color steel sandwich panel is made of two layers of metal face plate and middle polymer heat insulation inner core. It has the characteristics of simple installation, light weight, environmental protection and high efficiency. Moreover, the closed-cell molecular structure used in the filling system can prevent condensation of water vapor. The forming of the outer steel plate takes full account of the structural and strength requirements, and takes into account the beauty. The inner steel plate is formed as a flat plate to meet various needs. There are two kinds of metal panel and non-metal panel. Metal panels are easy to process and can be made into various shapes. However, in some cases, non-metallic panels play a more important role than metal panels, such as corrosion resistance and impact resistance.
Coloured steel sandwich plate has not only high mechanical strength and easy forming performance of iron and steel materials, but also good decorative and corrosion resistance of coating materials. Coloured steel sandwich panel is a new material respected in the world today. 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 movable room has shown more and more powerful 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 commonly used thermal insulation materials of the composite plate are rock wool, glass fibre wool, polystyrene (EPS), polyurethane, etc. The thermal conductivity is low, so the movable room, integrated house and steel structure workshop have good thermal insulation effect. High-strength color steel plate uses high-strength steel plate as the base material (tensile strength 5600kg/cm), plus the most advanced design and rolling forming. Therefore, the color steel plate movable room has excellent structural characteristics.
The core of color steel sandwich panels is mainly phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, three polyester and rock wool. Phenolic foam has excellent fire resistance and heat preservation performance. It is irreplaceable for other materials. For example, phenolic foam insulation is 2 times more than polystyrene, and its fire resistance is also better than that of polyurethane. To be high, polyurethane will release heavy smoke containing hydrogen cyanide when burning.
