Colour Coated Steel Rock Wool Sandwich Panel Roofing Sheets Fire
Protection Rating A1
Product Name: Rock Wool Sandwich Panel
The sandwich plate is composed of two layers molding metal panels
(or other materials of panels) and macro molecule insulated inner
core which is directly foamed and cured and molded in the middle of
panel, which is convenient for installation, light and efficient.
The filling system is also made of closed cell molecular structure
to avoid condensation of moisture.

Classification of sandwich plate
1. On core materials aspect, it is divided into six categories:
a) The polyphenyl sandwich plate is EPS sandwich plate (it is the
most widely brand in current market);
b) Extruded polystyrene sandwich plate is XPS sandwich plate;
c) Rigid polyurethane sandwich plate is PU sandwich plate;
d) Three polyester sandwich plate is PIR sandwich plate;
e) Phenolic aldehyde sandwich plate is PF sandwich plate
f) The rock wool sandwich plate is RW sandwich plate.
2. On panel aspect, it is divided into two categories:
Metal panel and non-metal panel. The metal panel is easy to be
processed into various shapes, but the non-metal panel plays other
more roles than metal panel in some cases, such as corrosion
resistance and impact resistance.
1. Light-weight, the weight per m2 is lower than 24kg, which can
fully reduce the structure cost.
2. The characteristics of rapid installation and light dead weight,
plugging, installation and cutting randomly determine simple
installation, and they can improve efficiency and save duration.
3. Fireproof, the surface material and insulation material of
composite sandwich plate of color steel are noncombustible or
fire-retardant materials, and they can meet the requirement of fire
4. Fire resistance, the color steel plate can be kept for 10-15
years through special coating treatment, and it is sprayed with
anti-corrosive paint every ten years, and the service life of the
plate is above 35 years
5. Beautiful, there are more than dozens of colors of clear lines
of profiled steel plate, which can meet the demand of any style of
6. Thermal insulation, the common insulation materials include:
Rock wool, glass fiber cotton, polystyrene,polyurethane with low
heat conductivity coefficient and good thermal insulation effect.
7. Environmental protection and noise insulation, the sound
insulation of composite plate is 40-50 decibels,which is a very
effective sound insulation material.
8. High plasticity, the profiled steel sheet can be cut randomly,
and it can meet the demand of special design.
9. High strength, the high strength steel plate is used as base
material, the anti-tension strength is 5600(kg/cm2),and it has
superb structural characteristics in combination with the most
advanced design and rolled forming.
10. Corrosion and shock resistance.
