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. Sandwich Panel Filling system is also used to close the molecular structure, 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, Sandwich Panel and takes into account the appearance, the inner layer is formed into a flat plate to suit various needs.
Sandwich board characteristics
1, the quality of light weight per square meter below 24kg, can fully reduce the structural cost.
2, the installation of fast and light weight, plug, Sandwich Panel 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, with a special coating of colored steel sheet up to 10-15 years, Sandwich Panel after every ten years spraying anti-corrosion coating, sheet life of 35 years
5, beautiful, pressure plate clear lines up to dozens of colors, Sandwich Panel 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, 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 using high strength steel as the substrate, Sandwich Panel tensile strength of 5600 (kg / cm2), coupled with the most advanced design and roll forming, with excellent structural characteristics.
Sandwich board classification
1. There are six kinds of core material:
Polystyrene sandwich panels that EPS sandwich panels (currently on the market, Sandwich Panel the most widely used varieties);
Extruded polystyrene sandwich panels that are XPS sandwich panels;
Rigid polyurethane sandwich panels that PU sandwich panels;
Trimer sandwich panel that is PIR sandwich panels;
Phenolic sandwich panels that are PF sandwich panels;
Rock wool sandwich panels are RW sandwich panels.
