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:Measures to prevent rust in welded seam of steel structure
95% pure zinc protective film can effectively resist rust and corrosion, providing years of rust protectionBecause of the strong permeability, after the protective film has been scraped, the zinc can protect the metal from corrosionRepairing damaged metal surface is effective, used for welding seam repair.
Q:What is pre assembled steel structure, what is called steel structure assembly?
Each component is connected together according to the requirements of the drawings, and the size of each assembly meets the requirements of the drawings, and whether the assembly holes meet the requirements of the installation. The pre assembled component shall be removed and moved to the site before installation.
Q:What is the difference between steel structure, light steel workshop, color steel room and movable room?
The frame of light steel structure buildings are H steel, I-beam, door type steel frame and Rachel purline, retaining structure is also useful for color plate and masonry wall. Multi-purpose in large companies, factories, warehouses, exhibition halls, integrated stadiums, shopping malls and so on.
Q:What is called a steel rivet?
In the 60 and 70s, high-strength bolts have not yet, welding technology is not as advanced as now, so many of the steel structure connections, by rivets, see the old movies, sometimes see.
Q:What does the horizontal support of steel structure mean?
Support is generally inclined to connect components, the most common are herringbone and cross shaped, the cross section can be steel pipe, H steel, angle steel, etc., the role is to enhance the stability of the structure.
Q:What is the life span of steel structure?
This is based on the quality of materials, design, load-bearing base of good or bad, as well as maintenance, protection, geographical location. Of course, the quality is good, careful, high life, generally in fifty years is no problem.
Q:What is the material in the steel structure?
Steel structure is mainly made of steel material, and it is one of the main types of building structure.
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:How much is the square metre of steel structure engineering cost now?
As we all know, the cost of the steel structure house is basically the same as that of the traditional concrete structure, but the use area can be more than 5%, and the average carbon emission should be about 35% lower. It is an ideal choice for the development of a low carbon economy.Light steel structure residential structure refers to the use of steel structure as load-bearing structure, with environmental protection, light body, energy-saving materials for residential structures. At present, the light steel structure in China's construction industry accounted for less than 5%, while Europe and the United States and Japan developed countries have reached more than 50%. The development of residential steel structure in our country is very large.
