We try to actively promote green buildings, vigorously develop light steel structure houses, improve the standards and quality of construction projects, improve the living environment of the people, and make the people live more peacefully and comfortably. For fresh things, everyone will definitely have all kinds of doubts. The following will solve these problems for everyone.
Question: What are the advantages of light steel construction over traditional homes?
Answer: Compared with brick-and-mortar houses, the light steel structure can avoid the waste of resources caused by earth-fired bricks. And because the wall thickness of the light steel structure is small, the effective use area can be increased compared with the brick-concrete structure. Compared with reinforced concrete houses, light steel structure can be recycled, and concrete can not be recycled, and it will definitely be construction waste in the future, causing environmental pressure. Moreover, the concrete takes a long time to be completely dried, so it is easy to cause indoor moisture, which is not conducive to human health.
Light steel structure has better seismic performance. Because the earthquake activity is left and right and up and down, the steel structure tightly connected by galvanized bolts constitutes a safe and stable box, and the wall will not collapse due to the shaking of the earthquake. Falling floor slabs endanger personal safety.
The dry construction method of light steel structure construction will not cause waste of water resources and save corresponding costs.
Question: the comparison between civil engineering and light steel structure houses?
||Light steel structure house
||Traditional brick house
||The composite wall has low heat transfer, cool in winter and cool in summer, and the thermal insulation performance of 140mm thick light steel structure composite wall is equivalent to 610mm thick traditional brick-concrete structure, saving about 32%.
||High heat conductivity, general insulation performance, high energy consumption
||The building is integrated with moisture-proof measures, no blind spots, and the wall is provided with one-way breathing paper, making the whole building a house that can breathe.
||No overall moisture protection measures, poor air permeability
||The building has light weight and high toughness. Due to the good structure of the “cage” structure, the damage caused by the earthquake load is minimal.
||Brittle structures are severely damaged under seismic loading
||The internal and external wall materials used can meet the fire rating requirements
||Rich in structural form compared to cost time and span
||Achieve large-span structure consumption materials, a single form
||Save half or more of the construction time compared to traditional brick-concrete houses, and they can be completed when they are completed.
||Long construction period and can not construction in cold winter areas
||Lightweight, most of the structures such as the beam truss can be prefabricated at the factory.
||Few prefabricated components
|Recycle and re-use
||Structural body components can be recycled and reused
||Unable to recycle
|Low carbon environmental protection
||Renewable resources, and can be naturally degraded, zero pollution, zero emissions, no dust, noise during house construction

||The light steel structure composite wall is thin, and the room rate is higher than that of traditional buildings by about 18%.
||The wall is too thick and the room rate is low.
||The construction process is to assemble the prefabricated components of the factory, using clean and simple, no wet operation.
||The construction process is complicated and requires a long maintenance cycle
Question: Can light steel structure houses handle real estate licenses? What are the procedures for running the department?
Answer: Steel structure houses can not do real estate licenses, and has nothing to do with the house itself. There is a great relationship with the nature of the land. The policies in each region are different. Many of our customers have also applied for real estate licenses. Like many civil engineering projects, it is not always possible to carry out real estate licenses. This issue has a lot to do with the local government.
Question: How to install the heating equipment in the light steel structure house?
Answer: If it is an ordinary radiator, it can be fixed directly on the wall. If it is floor heating, the floor heating can be installed on the cement pressure plate, which is no different from the traditional building.
Question: Which installations are responsible for light steel structure houses?
Answer: If it is a large-scale light steel structure housing project, it generally does not include interior decoration, civil engineering without doors and windows, and without foundation and ground. In addition, the exterior is fully decorated, and the sound insulation and waterproof function has been completed. Additional items can also be added according to the special requirements of the owner.
Question: What is the general price of light steel structure houses?
Answer: There is a general offer for houses with ordinary shapes and no special structure. For houses with complex structural shapes and special requirements, it is not suitable for general quotation. Whether it is ordinary or has special requirements, the exact quotation will be calculated according to the drawings.
Question: Is there a relationship between the height and price of light steel houses? What is the general height?
Answer: There will be a certain relationship, because the difference in height will result in different materials usage and working hours. The height of each floor is generally 2.5-3.4 meters per floor. The price is higher than your design.
Question: What materials are mainly used on the second floor of light steel houses? Can it be shock-absorbing, soundproof and waterproof.
Answer: There are two ways to do the second floor of a light steel house. 1 Pour the concrete floor on the basis of the cement fiber board, and then lay the tile, wooden floor or carpet. 2 After the waterproofing treatment is done on the basis of the cement fiberboard, the wooden floor or carpet is directly laid. There is nothing wrong with both approaches to waterproofing. the sound insulation layer is also formed between the ceiling of the first floor and the second floor.
Question: What is the live load of the second floor and roof of a light steel house? What is the wall?
Answer: The wind pressure on the wall is 0.4KN/M2 (40 kg), the constant load on the roof is 0.35KN/M2 (35 kg), and the live load on the roof is 0.5KN/M2 (50 kg). This value is the design standard for the East China region. Different values will change. The ground live load on the second floor is 0.31-0.36KN/M2 (310kg-360kg). If you have special needs, we can increase or decrease your design.

Question: Will there be any safety hazards in the installation of water and electricity in light steel houses?
Answer: No, we have reserved water and electricity safety holes at the beginning of the design, so there is no hidden danger of water and electricity. Because all the circuits in the light steel house are laid through the line pipe, and the water pipe is pressed after the test is completed, there is no need to worry about the water circuit.
Question: How do you prove that the sound insulation of light steel houses is better than that of civil works?
Answer: The sound insulation effect is an important indicator for evaluating residential buildings. The light steel house system is better than the traditional civil structure. It has been concluded through strict testing by relevant departments and long-term foreign application. The reason why it is good is that the wall of the light steel house is composed of two layers of inner and outer double-layer tension plates, breathing paper, extruded board, glass wire insulation, interior wall panels and exterior wall metal carved panels. Into the insulation and sound insulation, especially the 16mm polyurethane foam used in the exterior metal carved panels is the best thermal insulation material in the country, so the sound insulation effect is better than the civil construction.
