Product Description:

  EPS sandwich panel production process adopts the colored steel plate as surface board, and the core material is the self-extinguishing closed cell polystyrene foam, It is a kind of high-strength composited building materials, and it was formed in the automated continuous molding machine, by combining the pressed colored steel with the High Strength Adhesives. It has the characteristics of complete insulation and fire-proof, fast construction speed, durability, and beautiful appearance, etc.


The above sandwich panels have been widely used in warehouses, factories, exhibition hall, prefabricated house, container houses and other industrial and civil buildings

Q:What are the types of steel structures
Steel structure is a structure made of steel material, and is one of the main types of building structures. 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:In steel engineering, what is called rigid connection? What is articulated? What kind of nodes or structural parts are applicable to the two?
To connect by means of hinges. A device or part commonly used in two parts of a machine, vehicle, door, window, and implement, such as articulated trolley buses, articulated freight cars, articulated buses.
Q:Name of steel structure awning
Awning shed products are unique in shape, beautiful and generous, and what is more outstanding is its high strength, high durability, anti ultraviolet and insulation effect. According to the JIS standard, the snow resistance (load 875px snow pack) is effectively considered in terms of safety, and strong wind resistance (strong resistance to 42m/s wind).
Q:What is the edge of the steel structure?
Water is a kind of waterproof technology in construction, popular said is actually in the wall and the roof, is at the intersection of waterproofing in all need waterproof treatment that is the facade, with waterproof material to wrap the corner. And different apron
Q:What kind of material test is necessary for steel structure engineering?
Steel structure engineering needs the steel structure raw material (steel plate) test, testing, welding test, welding seam without damaging the ball and a bolt ball test, fire coating test, deflection detection of these almost.
Q:What kind of steel is used in steel structure?
It depends on the kind of steel structure. There are thousands of kinds or even thousands of kinds of steel. General steel construction refers to the construction of steelIf the construction of steel, then basically steel Q235, Q345, Q390, Q420 four kinds of steel. Q235 is plain carbon steel. The latter three are low alloy steels. Corrosion depends on the structure of the steel structure and the use of parts, ships, viaducts, a corrosion resistant period of more than 20 years, but not up to this standard, foreign countries are basically sprayed aluminum and zinc sprayed. Antiseptic method. The tall tower structure of the TV tower mast varies from 10 to 20 years. The general steel structure must basically be more than 5 years.
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:Is the metal structure the same as the steel structure?
The metal structure is a general term, including the steel structure, aluminum alloy structure, etc.. Somewhere, the steel structure is confined to the structure made of steel. In the past, aluminum alloy structures were seldom used, and the metal structures were basically equal to steel structures. Now, the aluminum alloy structural design code has been promulgated and implemented, the aircraft also use titanium alloy structure, metal structure of the scope is more extensive.
Q:What does "HW350x350" mean in steel structures?
HW350X350 is a model of hot-rolled wide flange H steel. The standard method is "HW350X350""HW350X350 has two specifications, one is HW350X350X12X19 (high X, wide X, web thick X flange thickness), and one is very use specifications, used very few, the cross section is HW344X348X10X16
Q:What are the meanings of I-beam BH300 x 200 x 6 x 8 on steel structures?
The ratio of the area of a longitudinal force (tension or pressure) to the effective area of a member (the axial compression member is a full cross section). The reinforcement ratio and the reinforcement ratio of the compression bar are calculated respectively. Formula: P =A (s) /bh (0). Here is the angle brackets below.Type: A (s) is the cross-sectional area of the longitudinal reinforcement in tension or compression zone; B is the width of the rectangular section; H (0) is the effective height of the cross section. The reinforcement ratio is a parameter that reflects the number of reinforcement.The minimum reinforcement rate is that, when the beam reinforcement ratio is very small, the beam tension zone after cracking, the steel stress tends to yield strength, the reinforcement rate is called the minimum reinforcement ratio (min). The minimum reinforcement ratio is determined according to the principle that the ultimate flexural capacity M (U) of the member section is equal to the bending moment M (CR) equal to the tensile moment of the concrete member under tension.
