The component element of steel structure engineering is mainly made of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or parts are usually connected by welds, bolts or rivets, which is one of the main types of building structures.Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.Then the advantages of steel structure engineering mainly include the following two points:

       On the one hand, the thermal insulation materials used in steel structure engineering are mainly glass fiber cotton, which has good thermal insulation effect.The insulation board used for the external wall can effectively avoid the phenomenon of “cold bridge” of the wall and achieve better insulation effect.The thermal resistance of R15 insulation cotton with the thickness of about 100mm can be equivalent to the brick wall with the thickness of 1m.

       On the other hand, the advantage of steel structure project is that the sound insulation effect is an important index to evaluate the residence. The windows installed in the light steel system are all made of hollow glass, which has good sound insulation effect, with the sound insulation reaching more than 40 decibels. The wall composed of light steel keel and heat insulation material gypsum board has a sound insulation effect of up to 60 decibels.

       1、 It has very good seismic resistance. The top of villas on lower floors are mostly slopes, so the roof structure is often triangular type made of cold-formed steel products, and then combined with light steel products and gypsum board, a very stable structural system is formed, which can be very earthquake resistant, so it is generally very stableIt is suitable for earthquake prone areas.

      2、 The weight of steel structure building is only one fifth of brick concrete structure, which can withstand 70m / s wind and reduce a lot of losses.

　   3、 This kind of building structure has good durability, which can reduce the impact of steel plate corrosion, increase the service life of steel products, and make the whole building life longer.

4、 This kind of building structure also has a good effect of heat preservation and insulation.For example, a 100 mm thick insulation thermal resistance of 15 is basically equal to a 1 m thick brick wall.

5、 An important index to evaluate the modern building is to see whether its sound insulation effect is good. This building structure also has good sound insulation, and the sound insulation effect can reach 40 decibels.

6、 This kind of building structure is very healthy, which can reduce environmental pollution to a large extent. Basically, all the waste materials can be recycled to meet the requirements of environmental protection, which is more conducive to health.

      7、 Steel structure building also has comfort and convenience, can adjust the air humidity, but also can be efficient construction without environmental impact.
