|Title||Color steel sandwich panels and ordinary board panels|
|Description||China PPGI corrugated roofing sheet manufacturer said that the color steel sandwich panel is a new type of material in the future construction, which not only can be very flame retardant, but also environmentally friendly and efficient. The color steel sandwich panel is made of two upper and lower metal panels and a middle layer polymer insulated inner core. It has the characteristics of easy installation, lightweight, and environmental protection. The color steel sandwich panel product is composed of two layers of formed metal panels (or other material panels) and a polymer insulated inner core that is directly foamed and matured in the middle of the panel. These sandwich panels are easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure that prevents condensation of water vapor. The formation of the outer steel plate fully considers the structure and strength requirements and makes the overall appearance beautiful. The inner surface layer is formed into a flat plate to meet various needs. There are six types of core materials: polystyrene sandwich panels, ie EPS sandwich panels (the most common type on the market), extruded polystyrene sandwich panels, ie XPS sandwich panels, rock wool color steel sandwich cores. Plate, rock wool color steel sandwich panel, rigid polyurethane sandwich panel, ie PU sandwich panel, three polyester sandwich panel, ie PIR sandwich panel, phenolic sandwich panel, ie PF sandwich panel, rock wool sandwich panel RW sandwich panel. The PPGI corrugated roofing sheet manufacturer says there are two types of panels: metal panels and non-metal panels. Metal panels are easy to process and can be made into a variety of shapes, but in some places, non-metallic panels have the effect of metal panels, such as corrosion resistance and impact resistance. Commonly used in large industrial plants, warehouses, stadiums, supermarkets, hospitals, cold storage, mobile homes, building plus layers, clean workshops and places that need insulation and fire protection. The sandwich panel has a beautiful appearance, bright color, and good overall effect. It integrates bearing, heat preservation, fireproof and waterproof, and does not require secondary decoration. It is quick and convenient to install, short construction period and good comprehensive benefit. It is a universal use. Highly efficient and environmentally friendly building materials with potential.|
