Sandwich panel definition
Sandwich panel products are formed by two layers of metal panels (or other materials panel) and directly in the middle of the panel foam, aging molding polymer insulation core composition. These sandwich panels are easy to install, lightweight and efficient. Filling system is also used closed-cell molecular structure, can prevent condensation of water vapor.  The forming of the outer steel plate takes full account of the structural and strength requirements, taking into account the aesthetics, the inner layer is formed into a flat plate to meet various needs.
1. Core material to be divided into six types:
Polystyrene sandwich panels that EPS sandwich panels (currently on the market, the most widely used varieties);
Extruded polystyrene sandwich panels that XPS sandwich panels;
Rigid PU sandwich panel PU sandwich panel;
Tri-polyester sandwich panel or PIR sandwich panel;
Phenolic sandwich panel or PF sandwich panel;
Rockwool sandwich panel that is RW sandwich.
Foam metal sandwich panel
2. There are two types of panels:
Metal panel and non-metallic panel two. Metallic panels are easy to machine and can be made in a variety of shapes, but in some applications non-metallic panels have a role that metal panels can not, such as corrosion and impact resistance.
Sandwich panel features:
1, light weight less than 24kg per square meter, you can fully reduce the cost of the structure.
2, fast and light weight installation, docking, installation and cutting characteristics can be freely decided to install its simple, can improve efficiency and save time.
3, fire prevention, Caigang compound with the core board material and insulation materials for the non-burning or flame retardant materials, to meet fire safety requirements.
4, fire-resistant, special coating color steel plate up to 10-15 years after the new, every 10 years after the anti-corrosion coating paint, plate life of 35 years
5, beautiful, pressure-type steel plate clear lines up to dozens of colors, can meet the needs of any style of building
6, thermal insulation Common insulation materials are: rock wool, glass fiber cotton, polystyrene, polyurethane, etc., low thermal conductivity, with good thermal insulation effect.
7, environmental noise, composite panels noise intensity of up to 40-50 dB, is a very effective noise insulation material.
8, strong plasticity can be cut any type of steel, enough to meet the special needs of the design.
9, high-strength high-strength steel as the substrate, the tensile strength 5600 (kg / cm2), coupled with the most advanced design and roll forming, with excellent structural characteristics.
Application of sandwich panels
Sandwich panels for large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storage, mobile homes, buildings plus layers, clean workshop and the need for thermal insulation fire place. Sandwich plate appearance, beautiful color, the overall effect is good, it sets the load-bearing, thermal insulation, fire protection, waterproof in one, and without secondary renovation, is a wide range of uses, especially in the construction of temporary facilities such as offices, warehouses , Fences, and so on, but also embodies the civilized construction of modern construction sites, especially in the rapid installation put into use, can be installed in removable, materials turnover index, have obvious advantages, significantly reduce the construction site temporary facilities costs , Will be an indispensable new light building materials.
