Sandwich board more and more widely used, different materials, sandwich board with the use of features and features are not the same. Polyurethane sandwich panels are one of the more common sandwich panels.
Sandwich panels are composed of two layers of metal panels (or other material panels) and directly in the middle of the panel foam, maturing the formation of polymer insulation core composition. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used to close the molecular structure, Sandwich Panel you can put an end to the condensation of water vapor. The forming of the outer steel sheet takes into account the structural and strength requirements, taking into account the aesthetic, the inner layer forming into a flat plate to meet the needs
Sandwich board characteristics
1, the quality of light weight per square meter below 24kg, Sandwich Panel can fully reduce the structural cost.
2, the installation of fast and light weight, plug, install and can cut the characteristics of arbitrary, to determine the installation of simple, can improve efficiency and save time.
3, fire, color steel composite plus core board of the surface material and insulation materials for non-burning or flame retardant materials, to meet the fire safety requirements.
4, fire-resistant, Sandwich Panel with a special coating of colored steel sheet up to 10-15 years, after every ten years spraying anti-corrosion coating, sheet life of 35 years
5, beautiful, pressure plate clear lines up to dozens of colors, with any style of the building needs
6, thermal insulation commonly used insulation materials are: rock wool, glass fiber cotton, polystyrene, polyurethane, low thermal conductivity, with a good thermal insulation effect.
7, environmental protection, noise, Sandwich Panel composite board noise intensity up to 40-50 dB, is a very effective sound insulation material.
8, plastic flexible steel plate can be arbitrarily cut, enough to meet the needs of special design.
9, high-strength high-strength steel plate as the substrate, Sandwich Panel tensile strength of 5600 (kg / cm2), coupled with the most advanced design and roll forming, Sandwich Panel with excellent structural characteristics
