Product Description:

The new type of polyurethane wall panel

1.New fireproof rock wool sandwich board uses two-layer high quality colored steel sheet or other precision profiled metal plate as the panel board. After the board is rolled and shaped, stripped rock wool should be turned 90°(make its fiber perpendicular to upper and lower steel sheets), and then fire resistant bond with high strength and cohesion should be used for bonding the high quality rock wool with the metal panel together, thereby composing beautiful, smooth and rigid building board. The shaped board has excellent fire prevention, thermal insulation and environmental protection features and provides one superexcellent choice for industrial building enclosure system.
2. POILISOCYANURATE, abbreviated as PIR; composite boards developed by DUOWEI use excessive sulfone isocyanurate, so ring structure of chemical compound and higher sulfone isocyanurate index form the dense PIR, thereby making interior rigid foam more stable and have high heat resistance and flame resistance. Experiment shows that the bubble can endure 200 ℃ in a short time and can endure 160℃ in a long time.


1.  A group corporation enjoying a competitive edge in the field of steel structure and new building boards, was founded in 1983 with the registered capital being 126 million yuan in exporting colored steel sheet, whose headquarters is located in Zhongguancun Fengtai Science Park, Beijing.

2. In the 1980s, CNBM has achieved professional advantages in the field of building metal profiled plates, and thenceforward it rapidly grew into an integrated enterprise group combining with design, manufacturing, construction, services and international trade. It is the main provider and market leader of steel structure and new construction boards in China. CNBM COLORED STEEL PLATE SANDWICH PANEL  currently has 16 branches and 10 manufacturing plants respectively in Beijing, Tianjin, Hebei, Shenyang, Harbin, Baotou and Urumqi,

whose products have been exported to over 40 countries and regions around the world.

3 Today, CNBM  is now the top 500 Fortun Globe has grown as an enterprise with such honors as Famous Trademark of China, the Best General Service Provider of Steel Structure Building System of China, the Leader of China's New Energy-efficient Construction Board Industry,

4. China’s Top ONE Construction Enterprises in the Steel Structure Industry, the High and New Technology Enterprises in Beijing, the High and New Technology Enterprises in Zhongguancun. DUOWEI is the main co-compiler of 16 national standards and industrial standards, and possesses the National Qualification of Class A in Architectural General Design, the Qualification of Grade A in Steel Structure Engineering Special Design, the Special-grade Qualification of Steel Structure Manufacturing, the Qualification of Class A in Professional Contracting for Steel Structure Projects and the certificate of ISO 9001: 2008 International Quality Management System Certification.

5.  CNBM benefits its cooperative partners continuously, like the building owners and investors, with exquisite technologies, high-quality

products and differentiated services. DUOWEI steel structure products featured in high-rise steel structure, space steel structure, heavy frame steel structure and light steel structure, has reached to 250 thousand tons in annual production; the annual production capacity of CNBM polyurethane energy-saving sandwich boards, new fireproof rock wool/glass fiber cotton sandwich boards has reached to 3 million square meters;

6. The annual production capacity of CNBM adjustable steel truss floor support plates and closed composite slabs is 5 million square meters; and the annual production capacity of CNBM colorful profiled steel plates has reached to 30 million square meters.

7.CNBM  Group has been making successes in serving PetroChina, Aerospace China,

China Nuclear Power, China FAW, China Guodian, China CNR, China Coal and other super large enterprises, and participating in national key projects, such as Hexie locomotive, National Grand Rocket, National Large Aircraft, Aerospace Coal Gasification, etc., and the group will continuously provide customers with innovative products and high-quality engineering services.

Q:I would like to ask, 50 thick metal sandwich panels per square meter generally have multiple ah?
This depends on your use, generally do sandwich board bulk density in accordance with the 120kg / cubic meter to count, the weight of each square about 6kg, plus 2 side of the steel plate, up to 6.5kg or so! [Rockwell Rock wool / Structural rock wool composite panel
Q:Color steel rock wool sandwich board price how much
The price by region, quality and demand to go, Tianjin is rock wool board manufacturers more cities, a single rock wool board, then many can do 40 or so per square meter
Q:With the production of sandwich panels can now control how many years?
In general, sandwich panel covers the house! On the iron thickness of 0.4, under the thickness of 0.326, you can protect the new 10 years, no later than 2 years spray a paint, up to 25 years! Aluminized zinc is longer,
Q:Color steel sandwich panel foam per cubic meter of weight is how much
The national standard is 18kg. Color steel sandwich panels are common in the current building materials, not only can be a good flame retardant and environmentally friendly and efficient. Caigang sandwich board has two layers of metal panels and the middle of the polymer core insulation from the suppression. With the installation is simple, light and efficient light and efficient features. And the filling system used to close the molecular structure of the closed, you can put an end to the condensation of water vapor.
Q:Hard polyurethane sandwich board combustion performance?
Some in the processing process plus a flame retardant ,,, and some did not add Plus the general is 3 to 5 seconds from the fire self-extinguishing
Q:What are the requirements for the use of foam sandwich panels for fireworks
Fire will not be used now
Q:The size of a standard sandwich panel is wide and wide
Width is generally 1 meter, the length is not limited, because taking into account the transport, usually between the length of 3-18 meters. Sandwich is divided into polyurethane, rock wool, glass wool, polystyrene, and so on, the general thickness of 50mm.75mm.100mm, thicker can do.
Q:Will the Yanmian sandwich color steel plate of the plant can reach the fire two grade requirements?
Yanmian sandwich color of the core material is basalt and other natural ore as the main raw material, the high temperature melt into the fiber, adding the right amount of binder, curing and made. Is the same type (sandwich panel series) in the fire resistance of the strongest of a new type of fire board. Applicable to drying room, paint room, industrial equipment, construction, ship insulation, noise, etc., at the same time for electronic clean room, clean room, explosion-proof fire shop ceiling, partition and so on. Fire time is 80 minutes. Some information on "with 600 ℃ fire resistance, fire rating to A level."
Q:Corrugated sandwich board is a kind of color steel plate? Thank you
Not sandwich plate refers to the middle folder with insulation layer, or other materials, composite sheet, strictly speaking, color steel corrugated board can be a color plate.
Q:What is the meaning of the bulk density of double-sided color steel polyurethane panels?
Double-sided color steel rigid polyurethane plate its bulk density of 35 ~ 40kg / m3, thermal conductivity: 0.018-0.023, low thermal conductivity, thermal performance.
