FAQ

The steel roof and the sandwich panel are waterproof
The two are actually the same class of things, sandwich panels only the color plate and insulation layer together, the installation more convenient. And the pressure steel roof need to lay another insulation layer and the roof. For both, the weak links of water are between the plates. In the actual project, the seam of the steel plate roof can be made in many forms, some of the overlapping form of waterproof performance is very good, and the common sandwich board roof shape is relatively simple, so the waterproof performance is also worse.
I would like to use Caigang sandwich panels to do the indoor ceiling ... how to use what keel .. how the ceiling thank you
It depends on the specific size, the span is not the same material is not the same
Foam sandwich board in line with the fire building requirements? There is no regulatory requirements in this area? I was in Jiangsu !! Thank you
Suggestions on Optimum Selection of Composite Materials in Fire Scene and Their Use in Construction. ??????????????????????????????? Metal surface polystyrene foam sandwich panels in the application of the most widely used, usually with the roof panels, partition panels, ceiling panels, polystyrene foam in the fire and high temperature melting, so the first case of the performance of the bubble Melt shrinkage for the plastic melt adhesion on the metal surface, the plate lost support and integrity, followed by the performance of combustion and smoke, used as a partition board and ceiling panels will quickly collapse, thus affecting the evacuation, resulting in personnel Casualties, used as a roof will be hanging on the steel beam and other roof load bearing components, as long as the overall steel roof trusses because of fire deformation and loss of support, will not collapse. Metal surface polyurethane sandwich panels in the case of fire mainly in the sandwich layer of smoldering and smoke, unburned parts will not be due to the rapid loss of high temperature support. Polystyrene foam composites coated with non-combustible materials such as concrete mortar will be lost in the case of fire. The support force collapses, flips, accelerates the spread of fire along the facade. ???????????????????????????????????????? Composite materials in the construction of the actual selection should take into account all aspects of the requirements, according to the actual needs of the scientific selection.
Color steel sandwich panels have what kind of ah?

Chongqing Caigang sandwich panel production
The thickness of the steel plate of the temporary space sandwich panel is generally thick
There are five and seven
What is the difference between a rock wool sandwich panel, an EPS sandwich panel and a polyurethane sandwich panel?
1, different fire rating: Yanmian sandwich panels for the A-level, EPS for the B3-class, polyurethane B1 level. 2, different insulation properties: the three polyurethane sandwich panels the best. 3, waterproof performance is different: the three polyurethane and EPS better than rock wool. 4, the density is different: rock wool bulk density is generally 120KG / cubic meter, EPS is generally 16, polyurethane is generally 40. All in all, the overall performance of polyurethane sandwich panels for the best, is the best choice for steel structure enclosure!
What is the level of fire protection for the production of polyurethane sandwich panels?
Class C plant.
What are the key notes when buying a rock wool sandwich panel?
There are four key factors: 1. Look at the use of construction: long-term construction or plant application of high quality (rock wool density is equal to 120kg / m3, the outer steel thickness is equal to 0.7mm, thickness of 100mm or more) of the rock wool sandwich panels, because the simple rock Cotton sandwich board after the installation of the surface easy to arch, bubble 2. Flatness: the requirements of the facade of the high demand, the use of mirror flat cotton wool sandwich panels, mirror flat cotton wool sandwich panels than the production of ripples difficult 3. Fire resistance: rock wool board production process should pay attention to the mouth and the mother of the filler, filled with rock wool board fire performance, filled with polyurethane and other materials, poor fire performance 4. Gongkou and the mother after the joint, the horizontal joints at the level of high and low error, high-quality quality rock wool board error is very small, low-end products will be interested in the horizontal slit to 10mm desalination level difference.
