 Advantages of SWE Polyurethane Sandwich Panels

1.Heat and sound insulation:The outer steel sheets can maintain the lastingness of the color of the building, and reduce the solar radiation and keep the appropriate indoor temperature. The high quality heat insulation materials are made with the adoption of polyurethane PU and (PIR) polyisocyanurate resin acid hydrogen containing no Chloro-fluoro-carbons (CFC).

2.A degree inflaming retarding:This system can effectively prevent the fire and prevent the fire from spreading during the cross construction and during the use of the boards

3.Environment protection:By learning after the successful experience in environment protection constructions from companies home and abroad and through our scientific analysis, we objectively bear the idea of “low carbon designing, environmental building materials and energy-saving technology” in mind.

4.Super-low heat conductivity:The lowest heat conducting coefficient of the heat insulation boards ensures that, under the condition that the thinnest heat insulation materials are used; the system can meet the energy-saving requirement and offer the strongest basic guarantee to meet the requirement of high standard heat insulation

5.SWE polyurethane roof panel are tightly connected blind nailing

6.Easily and quick installation

Q:Why steel structure is adopted in super high-rise buildings?
High strength, light weight and rigidity; homogeneous and isotropic material, an ideal elastic body, the most consistent with the basic assumption of the general engineering mechanics; material has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads; short construction period; the high degree of industrialization, can professional production of high mechanization degree;
Q:What is a steel structure?
Steel structure is mainly made of steel material. Mainly used in bridges, buildings, lighthouses, boats and other fields. In addition to the steel structure, there are wood structure, concrete structure, brick concrete structure and so on.
Q:What are the raw materials of steel structure?
Steel column, steel beam, column bottom plate, steel beam connecting plate, column beam connecting plate and so on, the material of these parts should be decided according to the design requirement.
Q:Excuse me, how to steel structure materials such as ah, how do I know purlin, bar, etc. What material is tied ah
These are commonly used in steel structure terminology or custom terminology, is the component is not material, the materials used are mostly profiles or cold bending materials, hardware manuals can not be found.
Q:How can the steel structure be laid with flame retardant PVC pipe?
The first group through the PVC tube and the PVC tube, steel wire hanging up this way in the fire and security are also relatively time-saving province cost way.
Q:How much is steel per square meter of steel foundation?
All types of foundations are not exactly the same. It is recommended that you calculate the total amount of reinforcement, and then divide the area to get the square meter content. This is more accurate.
Q:What does steel column support between columns mean?
These are all auxiliary components, is to keep the main component of the stable set: the pressure rod, rod / tube, compression support member in the bar, the casing should be a tube brace brace can only be used for tension, maintain the lateral stability of purlin;
Q:What does steel structure cross section L75*5 mean?
Steel structure is mainly made of steel material, and it is one of the main types of building structure. The structure is mainly composed of steel beams and steel plates, such as steel beams, steel columns, steel trusses and so on. Each component or component is usually connected with welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise and other fields.
Q:Steel structure lateral inspection "z15" what does that mean?
In general, thick steel plate is easy to produce lamellar tearing, because the thicker the steel plate, the more non-metallic inclusion defects, and the thicker the weld, the greater the welding stress and deformation. To solve this problem, it is better to use Z to steel. This kind of steel plate is on the basis of a certain structural steel (called parent steel). After special treatment and processing, the content of sulfur is less than 1/5 of the general steel, and the shrinkage of the section is more than 15%. The mechanical properties of steel plates in the thickness direction (mainly ductility) are called Z properties. The Z properties of steel plates can be obtained by tensile tests of specimens, usually measured by cross-sectional shrinkage. China's production of Z steel plate to mark is in the parent class followed by Z to steel steel plate Z15, Z25, Z35 grade mark, the number after the Z word for section shrinkage index (%).
Q:What is the material in the steel structure?
This material refers to the composition of steel structure required steel, plates can also be said to be reinforced beams, screws, flanges, stiffeners, and so on.
