Siding Composition

CNBM Siding consists of three layers: the top material isspecial aluminum-zinc coated metal board, the core material is rigidhigh-density Polyurethane foaming with fire-retardant treatment, and the backmaterial is fiber foil paper.

Product Features

Since CNBM Siding itself has the characteristics ofinsulation, water-proof and fire-retardant, lightweight anti-seismic,convenient construction, sound insulation and lower noise, environmentfriendly, and lasting beauty etc., in the meanwhile since its assembly methodof its siding body is simple and practical, without being limited by theseasons and environment, the installation is very safe and convenient, suitablefor four seasons.

Extensive Application Scope

CNBM siding is not only suitable for the newly set upbrick-concrete structure, framework structure, steel structure, lightweightbuildings, but also perfect for energy-saving reconstruction of the oldbuildings.

Q:The Development Trend of Color Steel Sandwich Board
Caigang sandwich board not only has high mechanical strength of steel, easy to shape the performance, but also both good decorative coating materials and corrosion resistance. Color steel sandwich panels are respected in today's world of emerging materials. With the progress of science and technology, environmental awareness, the improvement of people's living standards, Caigang sandwich panel activities room more and more show a strong vitality and broad market prospects, by the construction, home appliances, electrical and mechanical, transportation, interior decoration , Office appliances and other industries of all ages. Caigang sandwich panels used in the core of the main phenolic foam, polystyrene, extruded polystyrene, rigid polyurethane, trimer and rock wool, etc., and phenolic foam has excellent fire insulation properties, other materials can not be replaced , For example: phenolic foam insulation effect is more than 2 times the polystyrene, fire performance is also higher than the polyurethane, polyurethane combustion will release the hydrogen cyanide-rich smoke. With the country's attention to building fire and the introduction of relevant laws, I believe that phenolic color steel sandwich panels will create a blue sky in the construction field.
Q:What is the fire resistance time of the steel wool
Fire detection report is half an hour
Q:Is the polyurethane sandwich panel and foam board flame retardant?
On the market, the polyurethane foam flame retardant grade B1, B2, B3 three grades. Because of the cost, sandwich board with the majority of polyurethane material is B3 level, a small amount of B2 level, there are a small amount of special requirements B1 level. B1 level for the 'flame'; B2 level for the 'combustible'; B3 level for the 'flammable'. B1 grade oxygen index requirements of more than 30%; B2 level requirements of more than 26%, 26% of the following collectively referred to as B3 level. You said the flame retardant, it should be self-extinguishing from the fire. B2, B1 from the heat certainly no problem. A little better B3 (oxygen index of about 25%) can also be self-extinguishing, but more than B2 self-extinguishing time more than a few seconds. General oxygen index of less than 24%, it is difficult to self-extinguishing from the fire, will always burn, the greater the greater the burning. The The Oxygen Index: The concentration of oxygen required to stabilize the combustion in the oxygen and nitrogen gas mixture under the specified shape of the foam, the specified source of fire and the size of the flame. - For example, the better the flame retardant properties of the foam, the higher the concentration of oxygen needed to ignite the foam, the higher the oxygen index of the bubble
Q:Fire protection recommendations for color steel sandwich panels
Color plate can fire from six aspects: First, the use of good fire performance rock wool as a core material, which is a permanent solution. Second, in the process of building, the core material to stay away from welding, gas welding and other fire operations; Third, in the course of the use of some heat, the fire should not be next to the steel plate, to maintain a certain distance. If you want to set the kitchen in the color steel room, you need to have insulation layer, the wall should be installed fireproof rock insulation layer; Fourth, the wire, the cable is best not to pass from the core material, if necessary to wear protective cover Tube, socket, switch box should be used metal galvanized box and the use of mounted method; Fifth, indoor and outdoor with a simple fire fighting equipment, conditional installation of fire alarm should be convenient to facilitate the rapid evacuation of personnel; At least 6 meters to maintain a safe distance. Insulating materials that are not strictly flame-retardant are not flammable but are self-igniting. Strict, scientific and effective management, so that the fire away from the flammable color steel plate sandwich filler material, is to prevent color steel room fire is one of the important ways.
Q:Is there any profit in the rock wool sandwich panels?
Now the fire board profits should be about 20%.
Q:Hanging plate, color plate, sandwich panels, pressure plate the same?
Sandwich panels and Caigang sandwich panels is one thing, are double-color steel plate folder folder insulation material, food production workshop with sandwich panels can
Q:Density board, sandwich panels, solid wood particle board What is the difference between the three, which is better!
Solid wood particles board a little better
Q:Steel structure, activities, such as sandwich panels board generally what kind of self-tapping screws fixed ah?
Roof 75 stupid 135 self-tapping nail 100 stupid 165 self-tapping nail wall 50 stupid 75 self-tapping nail 75 stupid 100 self-tapping nail 100 stupid 125 tapping nail
Q:Can Caigang sandwich panels cover cottage? Is it possible to install it?
Color steel can be rocked cotton, rock wool non-flammable. There is a folder of foam, flammable, can not be used.
Q:Color steel plate wall how many meters a general support, corrugated color plate non-sandwich panels
Is there any angle between the top and bottom of the color plate? If not, the two panels at the junction should be set up a support point. If there is, 2-3 sets of color board can be set up to support, depending on the size of the project area average annual wind. We usually set up a 2 support.
