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:Definition of large steel structures
As a green environmental protection product, steel structure has the advantages of light weight, high strength and good seismic performance compared with the traditional concrete structure. The structure is suitable for the small proportion of the total load of the live load, and is more suitable for the construction of large span space structures and high-rise structures, and is suitable for construction on soft soil foundations. It also conforms to the national policy of environmental protection and conservation and intensive utilization of resources, and its comprehensive economic benefits are increasingly recognized by all investors, which will objectively urge designers and developers to choose the steel structure.
Q:What are the differences between steel structures and concrete structures?
Generally speaking, the steel structure is more energy saving, environmental friendly, high strength, good seismic resistance, fast construction speed and suitable for industrial production. The reinforced concrete structure corrosion performance is good, good insulation effect.
Q:What is the cushion block in the steel structure?
The cushion block is one of the structural measures of reinforced protective layer, which is most commonly used for surface mortar precast block, because of not well fixed reinforced steel protective layer, caused by the shift, if appear in the balcony can even cause collapse accident, resulting in plastic cushion block, bamboo pads to improve the block, but due to the lack of state specific provisions and norms lead to misunderstanding
Q:How much is one ton of steel structure installed?
If the pipe truss, or grid, to 2000-3000 tons of installation costs, depending on the complexity of the structure and the amount of steel to be fixed.
Q:What is the difference between a reinforced concrete structure and a steel concrete structure?
The reinforced concrete structure is a structure made of steel and concrete. The steel bars bear tension and the concrete bears the pressure. The utility model has the advantages of firmness, durability, good fire resistance, steel structure, steel saving, low cost, etc..Because the steel has good plasticity and toughness, and can have large deformation, can well withstand dynamic loads, the second steel good homogeneity and isotropy, an ideal elastic body, most consistent with the basic assumption of the general engineering mechanics. Therefore, the seismic performance of the steel structure of the seismic performance of reinforced concrete structures.
Q:What do we call a steel rivet in the hippocampus? What's the difference between them?
The pull nail of the hippocampus is a kind of metal link with unique structure and high riveting strength. It belongs to new fastening parts. The utility model has good filling hole performance, good air tightness and high riveting strength. The utility model is suitable for riveting fields with high surface requirements, high riveting strength and requirements for sealing performance.
Q:Is there any difference between the rigid and rigid connections in the design of steel structures?
Consolidation is a consolidation in the full sense. It can not move and rotate itself, but the rigid joint can not move or displace, but the whole displacement is possible.
Q:What is the ultimate capacity of steel structures?
A condition in which a structure or component reaches a specified limit for normal use or durability, referred to as the serviceability limitSuch as (1) affecting the normal use or appearance of deformation;(2) local damage (including cracks) that affects normal use or durability;(3) vibration affecting normal use;(4) other specific conditions that affect normal use;
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 does nonstandard steel structure mean?
There are non-standard and national standards, non-standard is a more special component, not conventional components,
