1. There are six types of core materials:
Polystyrene sandwich panel is EPS sandwich panel (currently the most widely used variety on the market);
Extruded polystyrene sandwich panel, ie XPS sandwich panel;
a rigid polyurethane sandwich panel, that is, a PU sandwich panel;
Three polyester sandwich panels are PIR sandwich panels;
Phenolic sandwich panel is PF sandwich panel;
The rock wool sandwich panel is the RW sandwich panel.
Foam metal sandwich panel
2. There are two types of panels:
There are two types of metal panels and non-metal panels. Metal panels are easy to machine and can be made into a variety of shapes, but in some cases non-metallic panels have the effect of metal panels, such as corrosion resistance and impact resistance.
Sandwich panel features:
1. The light weight per square meter is less than 24kg, which can fully reduce the structural cost.
2, the installation is fast and light, the characteristics of plugging, installation and free cutting, determine the ease of installation, can improve efficiency and save construction time.
3. Fireproof, the surface material and insulation material of color steel composite core board are non-combustible or non-combustible materials, which can meet the requirements of fire protection regulations.
4, refractory, special coated color steel plate protection for 10-15 years, after every 10 years spray anti-corrosion coating, sheet life of more than 35 years
5, beautiful, the shape of the profiled steel plate has as many as dozens of colors, which can meet the needs of any style of building.
6, thermal insulation commonly used insulation materials are: rock wool, fiberglass cotton, polystyrene, polyurethane, etc., low thermal conductivity, with good thermal insulation effect.
7, environmental protection and noise, composite board sound insulation strength of up to 40-50 decibels, is a very effective sound insulation material.
8, plasticity strong pressure type steel plate can be arbitrarily cut, enough to meet the needs of special design.
9. High-strength steel plate is made of high-strength steel plate with tensile strength of 5600 (kg/cm2). It is equipped with the most advanced design and roll forming, and has excellent structural characteristics.
