1、 Features of rock wool color steel plate 1. Good rigidity: because rock wool core material and two layers of steel plate are bonded as a whole, and work together, and the roof panel surface is wavy and profiled, its overall rigidity is far better than the field composite plate with rock wool (fiberglass wool) in the profiled plate. After the sandwich panel is fixed with the purlin through the connector, the overall rigidity of the roof is greatly improved, and the overall working performance of the roof is strengthened. 2. Reasonable connection mode: the rock wool roof panel adopts the connection mode, avoiding the hidden danger of water leakage in the roof panel joint, and saving the consumption of accessories. 3. Fixation method is firm and reasonable: rock wool roof panel is fixed with special M6 self tapping screw and purlin, which can effectively resist the external force such as typhoon. The self tapping screw is set at the crest position of the upper surface of the roof panel, and the special waterproof structure is adopted to avoid the weak point of waterproof. 4. Short installation period: the rock wool sandwich panel, as there is no need for secondary processing on site, can not only keep the surrounding environment clean and tidy, not affect the normal operation of other processes, but also greatly shorten the installation period of the panel. The daily average installation area of the rock wool sandwich panel is 600-800 ㎡. 5. Anti scratch protection: during the production of rock wool sandwich panel, polyethylene adhesive protective film can be pasted on the surface to avoid scratches or abrasion of the steel plate surface coating during transportation and installation. Guizhou color steel plate II. Advantages of rock wool color steel plate 1. Excellent fire performance: raw materials, production process and formula used for rock wool sandwich plate, which makes it have good fire performance. 2. Good heat preservation and insulation: the heat preservation and insulation performance of rock wool sandwich board is calculated based on the thermal conductivity coefficient of rock wool = 0.043w/m. K and the thickness of rock wool core material in corresponding proportion. 3. Remarkable sound absorption and heat insulation effect: sound insulation: rock wool sandwich board has a significant reduction effect on noise transmission, especially suitable for places with designated flights. In addition, after the rock wool roof panel is adopted, the impact of rain and hail on the roof steel plate of the building will cause indoor noise, which is also obviously weakened. Rock wool sandwich board gives full play to the unique performance of rock wool core material, and has significant effect on fire prevention, heat insulation, sound absorption and sound insulation. Guizhou color steel plate corrugated plate is also called profiled plate. It uses color coated steel plate, galvanized plate and other metal plates to roll and cold bend into various wave shaped profiled plates. It is suitable for industrial and civil buildings, warehouses, special buildings, roofs, walls and interior and exterior wall decoration of large-span steel structure buildings. It has the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake resistance, fire prevention, rain protection, long service life, maintenance free and so on. It has been widely used.
